A *query operation definition* is primarily composed of *fields*, which can have *arguments*, carry annotations called *directives*. 26 | 27 | 28 | ### Mapping SPARQL to JSON 29 | 30 | Each GraphQL field is associated with the following aspects: 31 | * a SPARQL pattern 32 | * of which one list of variables act as the *source* and 33 | * another list of variables that act as the *target*. 34 | 35 | 36 | ``` 37 | { 38 | 39 | } 40 | ``` 41 | 42 | 43 | 44 | # Reference 45 | 46 | 47 | 48 | 49 | 50 | -------------------------------------------------------------------------------- /rdf-processing-toolkit-cli/src/main/java/org/aksw/sparql_integrate/cli/main/SansaQueryRewrite.java: -------------------------------------------------------------------------------- 1 | package org.aksw.sparql_integrate.cli.main; 2 | 3 | /** 4 | * Idea to rewrite analytic queries to operations on RDDs. 5 | * If a query only has a BGP that has a star join on the subject then it can 6 | * be executed based on a scan of the subject-graphs of a subject-sorted rdd. 7 | * Certain aggregation over the whole dataset can be rewritten as a 8 | * local aggregation on the subject graph and a global one that accumulates the 9 | * local contributions. 10 | * 11 | */ 12 | //public class SansaQueryRewrite 13 | // extends TransformBase 14 | //{ 15 | // 16 | // 17 | // 18 | // public static pushGroup(OpGroup op, OpService target) { 19 | // for (ExprAggregator ea : op.getAggregators()) 20 | // } 21 | // 22 | // // op.getGroupVars() 23 | // 24 | // } 25 | // 26 | // public static Expr pushAggCount(AggCount agg, Query inner) { 27 | // agg.getExpr(); 28 | // 29 | // Expr innerCount = inner.allocAggregate(AggregatorFactory.createCount(false)); 30 | // } 31 | // 32 | // public static Expr pushAggSum(AggAvg agg, Query inner) { 33 | // Expr expr = agg.getExprList().get(0); 34 | // 35 | // Expr count = inner.allocAggregate(AggregatorFactory.createCount(false)); 36 | // Expr sum = inner.allocAggregate(AggregatorFactory.createSum(false, expr)); 37 | // 38 | // Expr result = new E_Conditional( 39 | // E_NotEquals(count, NodeValue.makeInteger(0)), 40 | // new E_Divide(sum, count), 41 | // NodeValue.makeInteger(0)); 42 | // return result; 43 | // } 44 | //} 45 | -------------------------------------------------------------------------------- /docs/integrate/canned-queries.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: Canned Queries 3 | parent: RDF/SPARQL Processing 4 | nav_order: 30 5 | layout: default 6 | --- 7 | 8 | ## Canned Queries 9 | RPT ships with several useful queries on its classpath. Classpath resources can be printed out using `cpcat`. The following snippet shows examples of invocations and their output: 10 | 11 | ### Overview 12 | ```bash 13 | $ rpt cpcat spo.rq 14 | CONSTRUCT WHERE { ?s ?p ?o } 15 | 16 | $ rpt cpcat gspo.rq 17 | CONSTRUCT WHERE { GRAPH ?g { ?s ?p ?o } } 18 | ``` 19 | 20 | Any resource (query or data) on the classpath can be used as an argument to the `integrate` command: 21 | 22 | ``` 23 | rpt integrate yourdata.nt spo.rq 24 | # When spo.rq is executed then the data is queried and printed out on STDOUT 25 | ``` 26 | 27 | ### Reference 28 | 29 | The exact definitions can be viewed with `rpt cpcat resource.rq`. 30 | 31 | * `spo.rq`: Output triples from the default graph. 32 | * `gspo.rq`: Output quads from the named graphs. 33 | * `spogspo.rq`: Output all triples followed by all quads. 34 | * `tree.rq`: Deterministically replaces all intermediate nodes with blank nodes. Intermediate nodes are those that appear both as subject and as objects. Useful in conjunction with `--out-format turtle/pretty` for formatting e.g. RML. 35 | * `gtree.rq`: Named graph version of `tree.rq`. 36 | * `rename.rq`: Replaces all occurrences of an IRI in subject and object positions with a different one. Usage (using environment variables): `FROM='urn:from' TO='urn:to' rpt integrate data.nt rename.rq` 37 | * `count.rq`: Return the sum of the counts of triples in the default graph and quads in the named graphs. 38 | * `s.rq`: List the distinct subjects in the default graph. 39 | 40 | -------------------------------------------------------------------------------- /docs/getting-started/index.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: Getting Started 3 | has_children: true 4 | nav_order: 20 5 | layout: default 6 | --- 7 | 8 | # Getting Started 9 | 10 | 11 | 12 | ### Downloads 13 | 14 | You can download RPT as self-contained JAR bundle, Debian package or RPM package from [RPT's GitHub release page](https://github.com/SmartDataAnalytics/RdfProcessingToolkit/releases). 15 | You can also [build](build) RPT from the source code. 16 | 17 | Note, that several aspects of RPT require appropriate [`--add-opens` JVM option declarations](build.html#jvm-options) to function correctly. The bundles have those proconfigured. 18 | 19 | ### Docker 20 | 21 | The quickest way to start an RPT instance is via docker. The container name is `aksw/rpt`. The latest stable version has the tag `latest` whereas the latest development version is available under `latest-dev`: 22 | 23 | `docker pull aksw/rpt` 24 | 25 | `docker pull aksw/rpt:latest-dev` 26 | 27 | 28 | For example, a typical invocation of the `integrate` command is as follows: 29 | 30 | `docker run -i -p'8642:8642' -v "$(pwd):/data" -w /data aksw/rpt integrate --server YOUR_DATA.ttl` 31 | 32 | * `-p'8642:8642'` exposes RPT's port on the host. The order is `-p PortOnHost:PortInsideContainer`. 33 | * `-v "$(pwd):/data"` mounts the current host directory under `/data` in the container 34 | * `-w /data` sets the container's working directory to `/data` 35 | * `YOUR_DATA.ttl` is foremost a path to a file relative to `/data` in the container. Since `/data` is a mount of your host directory, any relative paths inside your host directory should also work inside the container. 36 | 37 | Visiting [http://localhost:8642/](http://localhost:8642/) should then show RPT's landing page. 38 | 39 | -------------------------------------------------------------------------------- /docs/graphql/reference/bind.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: bind 3 | parent: GraphQL over SPARQL 4 | nav_order: 130 5 | layout: default 6 | --- 7 | 8 | ## GraphQL Directive: `@bind` 9 | 10 | The `@bind` directive is used to associate a field in your GraphQL query or schema with a SPARQL expression. Note that [`@pattern`](pattern) is for graph patterns rather than expressions. 11 | As bind only produces a single value from the input binding, its cardinality defaults to `@one`. Explicitly adding `@many` will cause the value to be wrapped in an array. 12 | 13 | ### Purpose 14 | 15 | The directive allows one to compute values for a field based on variables that are mentioned in any ancestor node. The most common use is to expose an entity's IRI (or blank node) as an `id` field. 16 | 17 | #### Usage 18 | 19 | The `@bind` directive supports the following arguments: 20 | 21 | - **`of`** (`String`): The value of `of` is a SPARQL expression. The mentioned variables must be defined in any ancestor or at the annotated field. 22 | - **`as`** (`String`): (optional) The variable for the expression result can be specified explicitly (by default an internal name is generated). 23 | - **`target`** (`Boolean`): (optional, defaults to `true`) Whether the `@bind` expression produces the target values for the annotated field. 24 | If `target` is `false` then the field introduces the specified variable that can be referenced from descendants without it becoming a target of the field. 25 | Multiple target variables are combined into a tuple based on the order of their appearance. 26 | 27 | #### Example 28 | 29 | Here is an example demonstrating how to define a `MusicalArtists` field using the `@bind` directive: 30 | 31 | ```graphql 32 | { 33 | MusicalArtists @pattern(of: "?s a ") { 34 | id @bind(of: "?s") 35 | } 36 | } 37 | ``` 38 | 39 | -------------------------------------------------------------------------------- /rdf-processing-toolkit-web-service/pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 5 | 4.0.0 6 | 7 | 8 | org.aksw.rdf-processing-toolkit 9 | rdf-processing-toolkit-parent 10 | 1.0.7-SNAPSHOT 11 | 12 | 13 | rdf-processing-toolkit-web-service 14 | jar 15 | 16 | 17 | 18 | 19 | org.aksw.jena-sparql-api 20 | jena-sparql-api-sparql-ext 21 | 22 | 23 | 24 | org.aksw.jena-sparql-api 25 | jena-sparql-api-core 26 | 27 | 28 | 34 | 35 | 36 | org.springframework.boot 37 | spring-boot 38 | 39 | 40 | 41 | org.springframework.boot 42 | spring-boot-autoconfigure 43 | 44 | 45 | 46 | org.springframework.boot 47 | spring-boot-loader 48 | 49 | 50 | 51 | org.slf4j 52 | slf4j-log4j12 53 | 54 | 55 | 56 | junit 57 | junit 58 | test 59 | 60 | 61 | 62 | 63 | -------------------------------------------------------------------------------- /docs/integrate/engines.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: Embedded SPARQL Engines 3 | parent: RDF/SPARQL Processing 4 | nav_order: 10 5 | has_children: false 6 | layout: default 7 | --- 8 | 9 | # Embedded SPARQL Engines 10 | 11 | The following engines can be used using `rpt integrate -e engine [--loc engine-specific-location]`. 12 | 13 | Embedded SPARQL engines are built into RPT and thus readily available.

EngineDescription
memThe default in-memory engine based on Apache Jena. Data is discarded once the RPT process terminates.
tdb2Apache Jena's TDB2 persisent engine. Use --loc to specfify the database folder.
binsearchBinary search engine that operates directly on sorted N-Triples files. Use --loc to specify the file path or HTTP(s) URL to the N-Triples file. For URLs, HTTP range requests must be supported!
remoteA pseudo engine that forwards all processing to the SPARQL endpoint whole URL is specified in --loc.
qleverThe blazing fast qlever triple store launched from its docker image via Java's TestContainers framework. Use qlever:imageName:tag to use a specific image - this image's command line interfaces for starting the server and creating the indexes must be compatible with the default image registered with RPT.

This directive can be used to either specify a single prefix with an IRI or map multiple prefixes to their corresponding IRIs. 11 | 12 | ### Usage 13 | 14 | The `@prefix` directive accepts two possible configurations: 15 | 16 | 1. **Single Prefix Definition**: Use the `name` and `iri` arguments to define a single prefix. 17 | 2. **Multiple Prefix Mapping**: Use the `map` argument to define multiple prefixes in a key-value format. 18 | 19 | #### Arguments 20 | 21 | - **`name`** (`String`): The prefix name to be used. 22 | - **`iri`** (`String`): The IRI (Internationalized Resource Identifier) associated with the prefix. 23 | - **`map`** (`Map`): A map of prefix names to their corresponding IRIs. 24 | 25 | #### Examples 26 | 27 | 1. **Single Prefix Definition** 28 | 29 | Define a single prefix using the `name` and `iri` arguments: 30 | 31 | ```graphql 32 | { 33 | field 34 | @prefix(name: "rdf", iri: "http://www.w3.org/1999/02/22-rdf-syntax-ns#") 35 | @prefix(name: "owl", iri: "http://www.w3.org/2002/07/owl#") 36 | } 37 | ``` 38 | 39 | 2. **Multiple Prefix Mapping** 40 | 41 | Define multiple prefixes using the `map` argument. As GraphQL does not allow the empty string `""` as a key, the `name/iri` form can be used in conjunction with map: 42 | 43 | ```graphql 44 | query MyQuery 45 | @prefix(map: { 46 | rdf: "http://www.w3.org/1999/02/22-rdf-syntax-ns#", 47 | rdfs: "http://www.w3.org/2000/01/rdf-schema#" 48 | }, name: "", iri: "http://my.domain/ontology/) 49 | { 50 | # ... 51 | } 52 | ``` 53 | 54 | #### Notes 55 | 56 | - When using the `map` argument, you can define multiple prefix-to-IRI mappings in a single directive instance. 57 | 58 | -------------------------------------------------------------------------------- /rdf-processing-toolkit-cli/src/main/java/org/aksw/named_graph_stream/cli/cmd/CmdNgsMap.java: -------------------------------------------------------------------------------- 1 | package org.aksw.named_graph_stream.cli.cmd; 2 | 3 | import java.util.ArrayList; 4 | import java.util.List; 5 | import java.util.concurrent.Callable; 6 | 7 | import org.aksw.named_graph_stream.cli.main.NgsCmdImpls; 8 | 9 | import picocli.CommandLine.ArgGroup; 10 | import picocli.CommandLine.Command; 11 | import picocli.CommandLine.Option; 12 | import picocli.CommandLine.Parameters; 13 | 14 | @Command(name = "map", description = "(flat-)Map each named graph to a new set of named graphs") 15 | public class CmdNgsMap implements Callable { 16 | 17 | @Option(names = { "-h", "--help" }, usageHelp = true) 18 | public boolean help = false; 19 | 20 | 21 | @ArgGroup(exclusive = true, multiplicity = "1") 22 | public MapSpec mapSpec; 23 | 24 | public static class MapSpec { 25 | /** 26 | * sparql-pattern file 27 | * 28 | */ 29 | @Option(names = { "-s", "--sparql" }, description = "sparql file or statement(s)") 30 | public List stmts = new ArrayList<>(); 31 | 32 | @Option(names = { "-g", "--graph" }, description = "set the graph of triples or quads") 33 | public String graph = null; 34 | 35 | @Option(names = { "-d", "--dg", "--default-graph" }, description = "map into the default graph") 36 | public boolean defaultGraph = false; 37 | } 38 | 39 | @Option(names = { "-o", "--out-format" }, description = "Output format") 40 | public String outFormat; 41 | 42 | 43 | @Option(names = { "-t", "--service-timeout" }, description = "Connect and/or query timeout in ms.

The incoming result set replaces the given query's 4 | query pattern - hence it is ignored and can be left empty such as in `sbs map -s 'SELECT * {}' input.rsj`. 5 | The main use case is to post process result sets that are assembled from multiple individual queries such as the output of the [Named Graph Streams (NGS)](README-NGS.md) tool which is part of the bundle. 6 | 7 | The typical conventions of the [RDF Processing Toolkit](README.md) apply: 8 | 9 | * The `SELECT` keyword is optional - so `?s { ?s a foaf:Person}` is equivalent to `SELECT ?s WHERE { ?s a foaf:Person }` 10 | * IRIs starting with `` will be substituted with environment variable values. There by `` yields a string and using double slashes such as ` a IRI>` yields IRIs. 11 | 12 | Example: 13 | ```bash 14 | sparql-integrate -o txt '( AS ?user) {}' 15 | 16 | ----------- 17 | | user | 18 | =========== 19 | | "raven" | 20 | ----------- 21 | ``` 22 | 23 | ```bash 24 | ➜ sbs -h 25 | Usage: sbs [-h] [COMMAND] 26 | SPARQL Binding Streams Subcommands 27 | -h, --help 28 | Commands: 29 | map Map bindings via queries 30 | filter Filter bindings by an expression 31 | ``` 32 | 33 | ```bash 34 | Usage: sbs map [-h] [-o=] [-s=]...

The RDF Processing Toolkit (RPT) integrates several of our tools into a single CLI frontend: 10 | It features commands for running SPARQL-statements on triple and quad based data both streaming and static. 11 | SPARQL extensions for working with CSV, JSON and XML are included. So is an RML toolkit that allows one to convert RML to SPARQL (or TARQL). 12 | RPT ships with Jena's ARQ and TDB SPARQL engines as well as one based on Apache Spark. 13 | 14 | The [`integrate`](integrate) command is the most versatile one: It accepts as arguments rdf files and sparql query/update statements which are run in a pipeline. The `--server` option starts a web server with SPARQL and GraphQL endpoints over the provided data. 15 | Using `integrate` with the `remote` engine allows RPT to act as a [SPARQL proxy](integrate/#example-4-sparql-proxy). 16 | 17 | RPT is Java tool which comes with debian and rpm packaging. It is invoked using `rpt ` where the following commands are supported: 18 | 19 | * [integrate](integrate): This command is the most relevant one for day-to-day RDF processing. It features ad-hoc querying, transformation and updating of RDF datasets with support for SPARQL-extensions for ingesting CSV, XML and JSON. Also supports `jq`-compatible JSON output that allows for building bash pipes in a breeze. 20 | * [ngs](named-graph-streams): Processor for named graph streams (ngs) which enables processing for collections of named graphs in streaming fashion. Process huge datasets without running into memory issues. 21 | * [sbs](sparql-binding-streams): Processor for SPARQL binding streams (sbs) which enables processing of SPARQL result sets in streaming fashion.

It allows you to define how variables within a SPARQL query map to the fields in your schema, providing flexibility in connecting fields to specific parts of the SPARQL graph. 11 | 12 | ### Purpose 13 | 14 | The directive is particularly useful in RDF and knowledge graph scenarios, where the data is modeled as triples. It lets you specify how variables in the pattern relate to each other across different fields. 15 | 16 | #### Key Concepts 17 | 18 | - **Source Variables (`from`)**: These variables represent the starting point of the field’s graph pattern. They typically join with the parent field’s target variables by default. 19 | - **Target Variables (`to`)**: These variables represent the output of the field’s graph pattern. 20 | - **SPARQL Pattern (`of`)**: The SPARQL graph pattern, expressed as a string, which specifies the relationship between variables. 21 | 22 | #### Usage 23 | 24 | The `@pattern` directive supports the following arguments: 25 | 26 | - **`of`** (`String`): The SPARQL graph pattern that defines the relationship between variables. 27 | - **`from`** (`String | [String]`): The source variable(s) for this field. If only a single variable is used, it can be passed directly as a string. Otherwise, an array is used. 28 | - **`to`** (`String | [String]`): The target variable(s) for this field. Similar to `from`, this can be a string or an array. 29 | 30 | #### Example 31 | 32 | Here is an example demonstrating how to define a `MusicalArtists` field using the `@pattern` directive: 33 | 34 | ```graphql 35 | { 36 | MusicalArtists @pattern(of: "?s a dbo:MusicalArtist", from: "s", to: "s") { 37 | label @pattern(of: "?s rdfs:label ?o", from: "s", to: "o") 38 | } 39 | } 40 | ``` 41 | 42 | #### Explanation 43 | 44 | 1. **MusicalArtists Field**: The `MusicalArtists` type is associated with the graph pattern `?s a dbo:MusicalArtist`, where the `s` variable acts as both the source and target. 45 | 2. **Label Field**: The `label` field is defined with a nested pattern `?s rdfs:label ?o`, where `s` is the source and `o` is the target. 46 | 47 | #### Rule for Implicit Joins 48 | 49 | By default, a field’s source variables (defined by `from`) are automatically joined with its parent’s target variables (defined by `to`). This allows seamless chaining of patterns without redundant variable specification. The precise join type is a [LATERAL join](https://github.com/w3c/sparql-dev/issues/100). 50 | 51 | #### Notes 52 | 53 | - If there is only one source or target variable, the array brackets (`[]`) can be omitted. 54 | - This directive is designed to handle more complex SPARQL graph patterns and facilitate better integration with RDF data sources. 55 | 56 | 57 | -------------------------------------------------------------------------------- /setup-latest-release.sh: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | # 4 | # Simple self-contained un-/install script for creating multiple commands from a single jar bundle 5 | # cmdToClass is the 'dataset' of shell command to java class mappings 6 | # As root, commands will be created under /usr/local/share/$pkgName/bin and then symlinked to /usr/local/bin 7 | # Uninstalling removes any command from /usr/local/bin that also exists in /usr/local/share/$pkgName/bin 8 | # For non-root users the folders are ~/Downloads/$pkgName and ~/bin 9 | # 10 | # Usage: 11 | # Installation is run by providing no additional argument: 12 | # ./setup.sh 13 | # To uninstall run 14 | # ./setup.sh uninstall 15 | # 16 | 17 | set -e 18 | 19 | arg="$1" 20 | 21 | pkgName="rdf-processing-toolkit" 22 | gitApiUrl="https://api.github.com/repos/SmartDataAnalytics/RdfProcessingToolkit/releases/latest" 23 | downloadPattern="download/.*-with-dependencies.jar" 24 | 25 | declare -a cmdToClass 26 | cmdToClass[0]="sparql-integrate sparqlintegrate" 27 | cmdToClass[1]="ngs" 28 | 29 | if [ "$USER" = "root" ];

This directive is particularly useful when the implicit join rule does not apply, such as when working with composite keys or specific variable subsets. 11 | 12 | ### Purpose 13 | 14 | While implicit joins automatically connect a parent’s target variables with a child’s source variables, the `@join` directive provides fine-grained control for cases where: 15 | - The parent field’s target variables form a composite key (e.g., multiple variables like `?cityName` and `?countryName`). 16 | - You need to join only a subset of these variables with the child field’s source variables. 17 | 18 | #### Arguments 19 | 20 | - **`parent`** (`String | [String]`): Specifies the parent field's variable(s) to be joined. 21 | - **`this`** (`String | [String]`): Specifies `this` field's variable(s) that should be connected with its parent’s variable(s). 22 | 23 | #### Usage 24 | 25 | The `@join` directive can be used when there is a need to manually specify how variables in a child field relate to those in a parent field, typically in more complex SPARQL scenarios. 26 | 27 | #### Example 28 | 29 | The following example demonstrates how to use the `@join` directive in a GraphQL schema: 30 | 31 | ```graphql 32 | { 33 | Location @pattern(of: "?x :city ?cityName ; :country ?countryName", 34 | from: ["cityName", "countryName"], to: ["cityName", "countryName"]) { 35 | 36 | cityName @pattern(of: "BIND(?x AS ?y)", from: "x", to: "y") @join(parent: "cityName") 37 | } 38 | ``` 39 | 40 | #### Explanation 41 | 42 | 1. **Location Field**: The `Location` field’s pattern includes a composite key formed by `cityName` and `countryName` (with both acting as target variables). 43 | 2. **CityName Field**: The `cityName` field’s pattern maps the value of `x` to `y`, where `y` is effectively a bound copy of `x`. 44 | 3. **Explicit Join**: The `@join(parent: "cityName")` directive ensures that the `x` variable (specified in `from: "x"`) joins with the parent’s `cityName` variable instead of relying on the implicit join rule. 45 | 46 | #### Variable Handling and Flexibility 47 | 48 | - When there is only a single variable to be joined, the array brackets can be omitted (e.g., `"cityName"` instead of `["cityName"]`). 49 | - The `@join` directive provides more control over complex joining scenarios, such as those involving composite keys or selective joins. 50 | 51 | #### Implicit vs. Explicit Joins 52 | 53 | - **Implicit Joins**: Automatically connect a parent’s target variables with a child’s source variables based on the default variable inheritance rule. No `@join` directive is needed in these cases. 54 | - **Explicit Joins**: The `@join` directive is required when more specific joins are needed, such as connecting only a subset of composite keys or customizing how variables are linked. 55 | 56 | #### Notes 57 | 58 | - Use the `@join` directive when you need more precision in how variables between parent and child fields are connected, especially when dealing with complex data models or SPARQL patterns. 59 | 60 | 61 | -------------------------------------------------------------------------------- /Makefile: -------------------------------------------------------------------------------- 1 | CWD = $(shell pwd) 2 | 3 | POM = -f pom.xml 4 | # Maven Clean Install Skip ; skip tests, javadoc, scaladoc, etc 5 | MS = mvn -DskipTests -Dmaven.javadoc.skip=true -Dskip 6 | MCIS = $(MS) clean install 7 | MCCS = $(MS) clean compile 8 | 9 | VER = $(error specify VER=releasefile-name e.g. VER=1.9.7-rc2) 10 | loud = echo "@@" $(1);$(1) 11 | 12 | # Source: https://stackoverflow.com/questions/4219255/how-do-you-get-the-list-of-targets-in-a-makefile 13 | .PHONY: help 14 | 15 | .ONESHELL: 16 | help: ## Show these help instructions 17 | @sed -rn 's/^([a-zA-Z_-]+):.*?## (.*)$$/"\1" "\2"/p' < $(MAKEFILE_LIST) | xargs printf "make %-20s# %s\n" 18 | 19 | distjar: ## Create only the standalone jar-with-dependencies of rpt 20 | $(MCCS) $(POM) package -Pdist -pl :rdf-processing-toolkit-pkg-uberjar-cli -am $(ARGS) 21 | file=`find '$(CWD)/rdf-processing-toolkit-pkg-parent/rdf-processing-toolkit-pkg-uberjar-cli/target' -name '*-jar-with-dependencies.jar'` 22 | printf '\nCreated package:\n\n%s\n\n' "$$file" 23 | 24 | rpm-rebuild: ## Rebuild the rpm package (minimal build of only required modules) 25 | $(MCIS) $(POM) -Prpm -am -pl :rdf-processing-toolkit-pkg-rpm-cli $(ARGS) 26 | 27 | rpm-reinstall: ## Reinstall rpm (requires prior build) 28 | @p1=`find rdf-processing-toolkit-pkg-parent/rdf-processing-toolkit-pkg-rpm-cli/target | grep '\.rpm$$'` 29 | sudo rpm -U "$$p1" 30 | 31 | rpm-rere: rpm-rebuild rpm-reinstall ## Rebuild and reinstall rpm package 32 | 33 | 34 | deb-rebuild: ## Rebuild the deb package (minimal build of only required modules) 35 | $(MCIS) $(POM) -Pdeb -am -pl :rdf-processing-toolkit-pkg-deb-cli $(ARGS) 36 | 37 | deb-reinstall: ## Reinstall deb (requires prior build) 38 | @p1=`find rdf-processing-toolkit-pkg-parent/rdf-processing-toolkit-pkg-deb-cli/target | grep '\.deb$$'` 39 | sudo dpkg -i "$$p1" 40 | 41 | deb-rere: deb-rebuild deb-reinstall ## Rebuild and reinstall deb package 42 | 43 | 44 | docker: ## Build Docker image 45 | $(MCIS) $(POM) -am -pl :rdf-processing-toolkit-pkg-docker-cli $(ARGS) 46 | cd rdf-processing-toolkit-pkg-parent/rdf-processing-toolkit-pkg-docker-cli && $(MS) $(ARGS) jib:dockerBuild && cd ../.. 47 | 48 | docker-deploy: ## Build and deploy the docker image 49 | $(MCIS) $(POM) -am -pl :rdf-processing-toolkit-pkg-docker-cli $(ARGS) 50 | cd rdf-processing-toolkit-pkg-parent/rdf-processing-toolkit-pkg-docker-cli && $(MS) $(ARGS) jib:build && cd ../.. 51 | 52 | release-bundle: SHELL:=/bin/bash 53 | release-bundle: ## Create files for Github upload 54 | @set -eu 55 | ver=$(VER) 56 | $(call loud,$(MAKE) deb-rebuild) 57 | p1=`find rdf-processing-toolkit-pkg-parent/rdf-processing-toolkit-pkg-deb-cli/target | grep '\.deb$$'` 58 | $(call loud,cp "$$p1" "rpt-$${ver/-/\~}.deb") 59 | $(call loud,$(MAKE) rpm-rebuild) 60 | p1=`find rdf-processing-toolkit-pkg-parent/rdf-processing-toolkit-pkg-rpm-cli/target | grep '\.rpm$$'` 61 | $(call loud,cp "$$p1" "rpt-$$ver.rpm") 62 | $(call loud,$(MAKE) distjar) 63 | file=`find '$(CWD)/rdf-processing-toolkit-pkg-parent/rdf-processing-toolkit-pkg-uberjar-cli/target' -name '*-jar-with-dependencies.jar'` 64 | $(call loud,cp "$$file" "rpt-$$ver.jar") 65 | $(call loud,$(MAKE) docker) 66 | $(call loud,docker tag aksw/rpt aksw/rpt:$$ver) 67 | $(call loud,gh release create v$$ver "rpt-$${ver/-/\~}.deb" "rpt-$$ver.rpm" "rpt-$$ver.jar") 68 | $(call loud,docker push aksw/rpt:$$ver) 69 | $(call loud,docker push aksw/rpt) 70 | 71 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # RDF Processing Toolkit (RPT) 2 | 3 | RPT makes RDF/SPARQL workflows on the command line easy. The RDF Processing Toolkit (RPT) integrates several of our tools into a single CLI frontend: It features commands for running SPARQL-statements on triple and quad based data both streaming and static. SPARQL extensions for working with CSV, JSON and XML are included. So is an RML toolkit that allows one to convert RML to SPARQL (or TARQL). RPT embeds several SPARQL engines, including Jena’s ARQ and TDB, as well as one of our own for SPARQL-based batch processing using Apache Spark. 4 | 5 | ## News 6 | * 2025-05-14 The fat-jar issue described below has been identified and will be fixed with the next release. 7 | * 2025-02-17 ⚠️ The fat-jar release of at least [v2.0.0-rc4](https://github.com/SmartDataAnalytics/RdfProcessingToolkit/releases/tag/v2.0.0-rc4) hangs a while during startup because it unpacks the jar. We are looking into how to fix this. The docker/rpm/deb releases do not appear to suffer from this issue. 8 | * 2025-02-17 Integration of the blazing fast [qlever](https://github.com/ad-freiburg/qlever) engine using `rpt integrate -e qlever data.ttl query.rq` with [v2.0.0-rc4](https://github.com/SmartDataAnalytics/RdfProcessingToolkit/releases/tag/v2.0.0-rc4). 9 | * 2024-12-22 Powerful support for zero-config ad-hoc [GraphQL-over-SPARQL queries](https://smartdataanalytics.github.io/RdfProcessingToolkit/graphql/)!

The triples related to a query represent an instance of a sophisticated domain model and are grouped in a named graph. Depending on the input size one can end up with millions of named graphs describing queries amounting to billions of triples. With ngs one can easily extract complete samples of the queries' models without a related triple being left behind. 19 | 20 | 21 | ## License 22 | The source code of this repo is published under the [Apache License Version 2.0](LICENSE). 23 | Dependencies may be licensed under different terms.

These directives are particularly useful in RDF and SPARQL-based contexts, where fields often correspond to graph patterns that involve relationships with varying cardinalities. 11 | 12 | ### Purpose 13 | 14 | These directives allow you to specify whether a field should be treated as a single-valued or multi-valued field. By default, fields are treated as multi-valued (`@many`), which is typical in RDF data where properties often have multiple values. 15 | 16 | #### Arguments 17 | 18 | Both directives accept the following arguments: 19 | 20 | - **`self`** (`Boolean`): Controls whether the directive applies to the field it appears on. 21 | - **`cascade`** (`Boolean`): Controls whether the directive cascades to child fields, affecting their cardinality as well. 22 | 23 | #### Default Behavior 24 | 25 | - **`@many`** is the default cardinality for all fields, as fields are often mapped to RDF graph patterns that can yield multiple target values (1:n relationships). 26 | - When applied, the directives determine whether a field is considered single-valued (`@one`) or multi-valued (`@many`), and can optionally cascade this behavior to child fields. 27 | 28 | #### Usage 29 | 30 | These directives can be applied to fields to control their cardinality and the cardinality of their child fields: 31 | 32 | - **`self`** (`true` by default): If `true`, the directive applies to the field itself. 33 | - **`cascade`** (`false` by default): If `true`, the directive applies to all child fields as well. 34 | 35 | #### Example 36 | 37 | Consider the following example: 38 | 39 | ```graphql 40 | { 41 | parent @one(self: false, cascade: true) { 42 | # The Parent field is still effectively @many, but the cardinality cascades to its children 43 | child1 # child1 inherits @one cardinality from Parent 44 | child2 # child2 also inherits @one cardinality from Parent 45 | } 46 | } 47 | ``` 48 | 49 | #### Detailed Explanation 50 | 51 | 1. **Parent Field**: The `@one(self: false, cascade: true)` directive is applied. This configuration means that: 52 | - `self: false`: The `@one` directive does **not** apply to the `Parent` field itself. The field remains multi-valued (`@many`). 53 | - `cascade: true`: The `@one` behavior cascades to the child fields (`Child1` and `Child2`), making them single-valued. 54 | 55 | 2. **Child Fields**: Both `child1` and `child2` automatically inherit the `@one` cardinality from the `Parent` due to the cascading effect. They are treated as single-valued fields. 56 | 57 | #### Understanding Cardinality Control 58 | 59 | - **`@one` Directive**: Specifies that the field is single-valued. If a field mapped to a SPARQL pattern yields more than one value, it will trigger an error in the GraphQL output. 60 | - **`@many` Directive**: Specifies that the field is multi-valued, allowing it to contain an array of values (this is the default). 61 | 62 | #### Practical Use Cases 63 | 64 | The `@one` and `@many` directives are useful when you need precise control over the expected cardinality of fields, especially in cases where: 65 | - You expect a single value (e.g., a unique identifier or singular property) and want to enforce this constraint. 66 | - You want to apply consistent cardinality rules across a hierarchy of fields using cascading behavior. 67 | 68 | #### Notes 69 | 70 | - By default, fields are assumed to be `@many` unless explicitly overridden. 71 | - The `cascade` argument allows you to propagate cardinality rules down to child fields, reducing the need for redundant annotations. 72 | 73 | -------------------------------------------------------------------------------- /rdf-processing-toolkit-pkg-parent/rdf-processing-toolkit-pkg-docker-cli/pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 5 | 4.0.0 6 | 7 | org.aksw.rdf-processing-toolkit 8 | rdf-processing-toolkit-pkg-parent 9 | 2.0.0-SNAPSHOT 10 | 11 | rdf-processing-toolkit-pkg-docker-cli 12 | jar 13 | 14 | rdf-processing-toolkit-cli 15 | 16 | 17 | ${project.artifactId}-${project.version}.jar 18 | 19 | 20 | ${docker.tag.prefix}${project.version} 21 | 22 | 23 | 24 | 25 | org.apache.maven.plugins 26 | maven-deploy-plugin 27 | 28 | true 29 | 30 | 31 | 32 | org.sonatype.plugins 33 | nexus-staging-maven-plugin 34 | 35 | true 36 | 37 | 38 | 39 | com.google.cloud.tools 40 | jib-maven-plugin 41 | 42 | 43 | 44 | docker.io/aksw/rpt:${docker.tag} 45 | 46 | 47 | 48 | 49 | 50 | 51 | eclipse-temurin:17-jre 52 | 53 | 54 | org.aksw.rdf_processing_toolkit.cli.main.MainCliRdfProcessingToolkit 55 | USE_CURRENT_TIMESTAMP 56 | 57 | --add-opens=java.base/java.lang=ALL-UNNAMED 58 | --add-opens=java.base/java.lang.invoke=ALL-UNNAMED 59 | --add-opens=java.base/java.lang.reflect=ALL-UNNAMED 60 | --add-opens=java.base/java.io=ALL-UNNAMED 61 | --add-opens=java.base/java.net=ALL-UNNAMED 62 | --add-opens=java.base/java.nio=ALL-UNNAMED 63 | --add-opens=java.base/java.util=ALL-UNNAMED 64 | --add-opens=java.base/java.util.concurrent=ALL-UNNAMED 65 | --add-opens=java.base/java.util.concurrent.atomic=ALL-UNNAMED 66 | --add-opens=java.base/sun.nio.ch=ALL-UNNAMED 67 | --add-opens=java.base/sun.nio.cs=ALL-UNNAMED 68 | --add-opens=java.base/sun.security.action=ALL-UNNAMED 69 | --add-opens=java.base/sun.util.calendar=ALL-UNNAMED 70 | --add-opens=java.security.jgss/sun.security.krb5=ALL-UNNAMED 71 | 72 | 73 | packaged 74 | 75 | 76 | 77 | 78 | 79 | 80 | org.aksw.rdf-processing-toolkit 81 | rdf-processing-toolkit-cli 82 | 83 | 84 | 85 | -------------------------------------------------------------------------------- /rdf-processing-toolkit-cli/src/main/java/org/aksw/rml/v2/cli/main/CmdRml2Exec.java: -------------------------------------------------------------------------------- 1 | package org.aksw.rml.v2.cli.main;
