Precompiled Binaries 62 | 63 | Download the binary from the [latest release](https://github.com/konradhoeffner/rickview/releases/latest) and run `rickview`. 64 | If you need binaries for a different operating system and CPU architecture combination, [let me know](https://github.com/konradhoeffner/rickview/issues/new). 65 | 66 | ## Compile it yourself 67 | Alternatively, you can compile it for your own platform with `cargo install rickview`. 68 | Or you can clone [the repository](https://github.com/konradhoeffner/rickview) and then `cargo build`. 69 | This requires you to install [Rust including Cargo](https://www.rust-lang.org/tools/install). 70 | 71 | ## Configure 72 | Default configuration is stored in `data/default.toml`, which you can override with a custom `data/config.toml` or environment variables. 73 | Configuration keys are in lower\_snake\_case, while environment variables are prefixed with RICKVIEW\_ and are in SCREAMING\_SNAKE\_CASE. 74 | For example, `namespace = "http://hitontology.eu/ontology/"` in `config.toml` is equivalent to `RICKVIEW_NAMESPACE=http://hitontology.eu/ontology/` as an environment variable. 75 | You need to provide a knowledge base file path or URL, the default is `data/kb.ttl`. 76 | If you don't, RickView will show a minimal example knowledge base. 77 | You can add custom HTML to the index page by adding a `data/body.html` file. 78 | You can add embedded CSS using the `css` environment variable. 79 | By default, the *Roboto* font is used which RickView hosts locally for robustness, speed and to prevent conflicts with European privacy laws. 80 | If this is not an issue for you and, for example, you want to display Chinese or Japanese characters, you could import a Google Font: 81 | 82 | css = "@import url('https://fonts.googleapis.com/css2?family=Noto+Sans+SC:wght@300&display=swap'); body {font-family: 'Noto Sans SC', sans-serif}" 83 | 84 | Compile and run with `cargo run` and then open in your browser. 85 | 86 | ## Supported File Formats 87 | The recognized RDF serialization formats and extensions to load a knowledge base are Turtle (`.ttl`), N-Triples (`.nt`), RDF/XML (`.rdf`), HDT (`.hdt`) as created by [hdt-cpp](https://github.com/rdfhdt/hdt-cpp) and zstd compressed HDT (`.hdt.zst`). 88 | 89 | ## Logging 90 | The default log level is "info" for RickView and "error" for libraries. 91 | Change the log level of RickView with the `log_level` configuration key or the `RICKVIEW_LOG_LEVEL` environment variable. 92 | Override this setting using the `RUST_LOG` env var to configure the log levels of dependencies, see the [env\_logger documentation](https://docs.rs/env_logger/latest/env_logger/), for example: 93 | 94 | RUST_LOG=rickview=debug cargo run 95 | 96 | ## Motivation 97 | Existing RDF browsers like [LodView](https://github.com/LodLive/LodView/) look great but use too much hardware resources as they are based on interpreted or garbage collected languages. 98 | This leads to long wait times and out of memory errors on typical small scale research VMs with dozens of docker containers for longtime archival of finished research projects, whose results should still be available to enable reproducible science. 99 | 100 | ## Goals 101 | Implement a basic RDF browser similar to LodView in Rust with the following properties: 102 | 103 | * speed 104 | * low resource utilization 105 | * good design 106 | * option to generate static HTML 107 | 108 | ## Stats 109 | All values are rounded and were measured on an old RickView version on an Intel i9-12900k (16 cores, 24 threads) with 32 GB of DDR5-5200 RAM and a Samsung SSD 980 Pro 1 TB on Arch Linux, standard kernel 5.18. 110 | The qbench2 test URI is . 111 | Stats for HDT, which uses much less RAM, are not measured yet. 112 | 113 | * Linux x86-64 release binary size (strip, fat link time optimization, all features): 4.1 MB 114 | * Linux x86-64 release binary size (strip, no link time optimization, all features): 5.8 MB 115 | * Docker image size: 9.7 MB 116 | * release compile time (strip, fat LTO, all features, cold): 52 s 117 | * release compile time (strip, no LTO, all features, cold): 19 s 118 | * RAM consumption (FastGraph, docker stats, HITO knowledge base 1.1 MB, idle): 10 MB 119 | * RAM consumption (FastGraph, docker stats, HITO knowledge base 1.1 MB, 30s max load): 15 MB 120 | * RAM consumption (LightGraph, docker stats, qbench2, 16.2 million triples, 3.6 GB N-Triples file): 2.568 GiB 121 | * RAM consumption (LightGraph, qbench2, normalized): 2.524 GiB 122 | * RAM consumption (FastGraph, docker stats, qbench2): 4.9 GB 123 | * graph loading time (FastGraph, qbench2, debug build): 548-552 s 124 | * graph loading time (FastGraph, qbench2): 47 s 125 | * graph loading time (LightGraph, qbench2): 40 s 126 | * HTML page generation time (LightGraph, qbench2): 1.9 s 127 | * HTML page generation time (FastGraph, qbench2): 6-58 ms 128 | * Turtle page generation time (FastGraph, qbench2): 6-35 ms 129 | 130 | ### Throughput Single Resource, HTML 131 | There is no page cache but there could still be internal caching benefits so this should be more elaborate in the future. 132 | 133 | $ wrk -t 24 -c 24 -d 30 http://localhost:8080/SoftwareProduct -H "Accept: text/html" 134 | Running 30s test @ http://localhost:8080/SoftwareProduct 135 | 24 threads and 24 connections 136 | Thread Stats Avg Stdev Max +/- Stdev 137 | Latency 9.79ms 3.25ms 26.92ms 56.40% 138 | Req/Sec 102.36 36.17 212.00 66.74% 139 | 73590 requests in 30.02s, 1.04GB read 140 | Requests/sec: 2451.31 141 | Transfer/sec: 35.43MB 142 | 143 | ### Throughput Single Resource, RDF Turtle 144 | 145 | $ docker run --network=host -v $PWD/ontology/dist/hito.ttl:/app/data/kb.ttl rickview 146 | $ wrk -t 24 -c 24 -d 30 http://localhost:8080/SoftwareProduct 147 | Running 30s test @ http://localhost:8080/SoftwareProduct 148 | 24 threads and 24 connections 149 | Thread Stats Avg Stdev Max +/- Stdev 150 | Latency 13.96ms 4.74ms 37.20ms 55.04% 151 | Req/Sec 71.77 26.17 121.00 66.43% 152 | 51572 requests in 30.02s, 567.72MB read 153 | Requests/sec: 1717.72 154 | Transfer/sec: 18.91MB 155 | 156 | ##

FAQ 197 | 198 | ### Why can't I use RickView with a Hash Namespace like http://example.com\#MyResource 199 | This is technically impossible for a server-side application by [the definition of a URI](https://datatracker.ietf.org/doc/html/rfc3986#section-3.5) because the fragment (the part after the hash) is client-only and never sent to the server. 200 | If you have an existing knowledge graph with a hash namespace, I recommend replacing the hash '`#`' with a forward slash '`/`'. 201 | 202 | ### Why is RickView necessary? Performance doesn't matter and RAM costs almost nothing! 203 | According to [Hitzler 2021](https://cacm.acm.org/magazines/2021/2/250085-a-review-of-the-semantic-web-field/fulltext?mobile=false), mainstream adoption of the Semantic Web field has stagnated due to a lack of freely available performant, accessible, robust and adaptable tools. 204 | Instead, limited duration research grants motivate the proliferation of countless research prototypes, which are not optimized for any of those criteria, are not maintained after the project ends and finally compete for resources on crowded servers if they do not break down completely. 205 | 206 | ### Can you implement feature X? 207 | I am very interested in hearing from you using it for your knowledge bases and am happy to assist you setting it up. 208 | Feature and pull requests are welcome, however the goal of RickView is to stay minimalistic and not serve every use case. 209 | Please also consider filling out the [survey](https://forms.gle/wqxdVdn4pDLXgyYZA) so I can see which features are most requested. 210 | 211 | ### Why no .env support? 212 | I think this would be overkill, as there is already a default configuration file, a custom configuration file, environment variables and Docker Compose supports `.env` out of the box as well. 213 | So my assumption is that you use the configuration file for local development and `.env` with Docker Compose. 214 | However if you need `.env` support outside of Docker Compose, just create an issue with a motivation and I may implement it. 215 | 216 | ### How can I use it with large knowledge bases? 217 | 218 | 1. Convert your data to the default HDT format using [hdt-cpp](https://github.com/rdfhdt/hdt-cpp). 219 | 2. Deactivate the title and type indexes by setting `large = true` in `data/config.toml` or setting the environment variable `RICKVIEW_LARGE=true`. 220 | 221 | Without the indexes, RickView's memory usage is only a few MB above the underlying [HDT Sophia adapter](https://github.com/konradhoeffner/hdt) in-memory graph, 222 | [see benchmarks](https://github.com/KonradHoeffner/sophia_benchmark/blob/master/benchmark_results.ipynb). 223 | For example, RickView on uses ~ 2.6 GB RAM and contains LinkedSpending 2015, which is 30 GB as uncompressed N-Triples and 413 MB as zstd compressed HDT. 224 | 225 | ### When to use compression and why not support other compression formats? 226 | 227 | [HDT](https://www.rdfhdt.org/) is a compressed binary format that still supports fast querying. 228 | It can be further compressed but then RickView needs to decompress it before loading, which in a test with a large knowledge base increased loading time from ~15s to ~17s. 229 | Because decompression is done in streaming mode, this restricts the available compressors and may even result in faster loading if you use a slow drive such as an HDD and a fast CPU. 230 | zstd was chosen because it compresses and decompresses quickly with a high ratio, supports streaming, and adds little overhead to the RickView binary. 231 | Brotli compresses extremely slowly on high compression settings while GZip results in much larger file sizes. 232 | If you need support for another streaming compressor, please [create an issue](https://github.com/konradhoeffner/rickview/issues). 233 | 234 | ### Why does it look exactly like LodView? 235 | 1. LodView looks beautiful and works well, the only problems are performance and to a lesser degree simple containerized deployment. 236 | 2. LodView is licensed under MIT, so that is allowed. LodView is Copyright (c) 2014 Diego Valerio Camarda and Alessandro Antonuccio. 237 | 3. I can focus my limited time on programming instead of design decisions. Other designs may follow later. 238 | 4. Users of LodView can switch without training. 239 | 5. Performance comparisons are easier when the interface is very similar. 240 | 241 | ### Can I deploy multiple knowledge graphs or one using OWL imports with a single instance of RickView? 242 | A single instance of RickView always loads a single file or URL and has a single namespace. 243 | All triples from the file that are within the namespace are displayed and mapped to the configured base path. 244 | OWL import statements are treated as normal triples and therefore have no special effects. 245 | URLs outside of the namespace are then resolved normally by the browser, so hopefully this ontology has an RDF browser behind it. 246 | If you want to host multiple ontologies or knowledge graphs with RickView, there are several options: 247 | 248 | #### Same Domain 249 | If they are on the same domain and you have control over the common prefix, you can specify that as the namespace. 250 | For example, the prefixes of [SNIK](https://github.com/snikproject/ontology) include: 251 | 252 | ```ttl 253 | @base . 254 | @prefix meta: . 255 | @prefix bb: . 256 | @prefix ob: . 257 | ``` 258 | 259 | RickView now runs on the server that hosts the website and other things, and all requests to `/ontology` are redirected to RickView. 260 | We [set the base to `/ontology`](https://github.com/snikproject/docker/blob/master/docker-compose.yml) and merge all SNIK files into a snik.ttl file, which is loaded by RickView. 261 | In the GitHub repository, the files are stored individually (meta.ttl, bb.ttl,...). 262 | There is a GitHub Workflow that runs [a merge script](https://github.com/snikproject/ontology/blob/master/.github/workflows/build.yml) 263 | with every commit, which validates and merges the files and pushes the result to a separate branch "dist". 264 | When loading the file with RickView, you only need to make sure that the server from GitHub also provides the file and not HTML. 265 | If you take it directly from the branch, you may need to load the URL with GitHub pages or a service that maps GitHub URLs into ones that download as the raw content. 266 | 267 | In practical use, we don't do it that way with SNIK, but have integrated the ontology as a Git submodule in the GitHub repository. 268 | The reason for this is that during the parallel development of the ontology and the Docker container, you can immediately see the changes without having to wait for the pipeline. 269 | Furthermore, you can then also check out an old state of the Docker repository and have the correct ontology version from that time. 270 | For example, if there were changes to the namespace, the RickView configuration must follow the ontology change, and if you want to look at it from two years ago for some reason, you can do that. 271 | Alternatively instead of the latest commit you can use the latest release via the "latest" reference, which works directly via . 272 | 273 | #### Different Domains 274 | If there are different domains or there is no common path over which you have control or the above methods are too convoluted for your use case, you can just run different RickView instances, which should have a low overhead. 275 | It can also be easier to manage if the different ontologies are in different repositories. 276 | For example, then you don't need a separate CI pipeline that merges the files with every commit or release and then attaches the merged file to the release. 277 | 278 | ## Community Guidelines 279 | 280 | ### Issues and Support 281 | If you have a problem with the software, want to report a bug or have a feature request, please use the [issue tracker](https://github.com/KonradHoeffner/rickview/issues). 282 | If have a different type of request, feel free to send an email to [Konrad](mailto:konrad.hoeffner@uni-leipzig.de). 283 | 284 | ### Citation 285 | 286 | [![DOI](https://zenodo.org/badge/472769298.svg)](https://zenodo.org/badge/latestdoi/472769298) 287 | 288 | There is no publication about RickView yet, so please cite our Zenodo archive for now. 289 | 290 | #### BibTeX entry 291 | 292 | @software{rickview, 293 | author = {Konrad H{\'o}ffner}, 294 | title = {{R}ick{V}iew: {L}ightweight Standalone Knowledge Graph Browsing Powered by {R}ust}, 295 | year = 2023, 296 | publisher = {Zenodo}, 297 | version = {x.y.z}, 298 | doi = {10.5281/zenodo.8290117}, 299 | url = {https://doi.org/10.5281/zenodo.8290117} 300 | } 301 | 302 | #### Citation string 303 | 304 | Konrad Höffner (2023).
