It is based on [Oxigraph](https://crates.io/crates/oxigraph). Oxigraph and Oxigraph Wikibase are in heavy development and not been optimized yet. ## Installation You need to have [a recent stable version of Rust and Cargo installed](https://www.rust-lang.org/tools/install). You also need [clang](https://clang.llvm.org/) to build RocksDB. To download, build and install the latest released version run `cargo install oxigraph_wikibase`. There is no need to clone the git repository. To compile the server from source, clone this git repository, and execute `cargo build --release` in the `wikibase` directory to compile the full server after having downloaded its dependencies. It will create a fat binary in `target/release/oxigraph_wikibase`. ## Usage To start a server that is synchronized with [test.wikidata.org](https://test.wikidata.org) you should run: ```bash ./oxigraph_wikibase --mediawiki-api https://test.wikidata.org/w/api.php --mediawiki-base-url https://test.wikidata.org/wiki/ --namespaces 0,120 --file test.wikidata ``` It creates a SPARQL endpoint listening to `localhost:7878/query` that could be queried just like Blazegraph. The configuration parameters are: * `mediawiki_api` URL of the MediaWiki API to use * `mediawiki_base_url` Base URL of MediaWiki pages like `https://test.wikidata.org/wiki/` for test.wikidata.org or `http://localhost/w/index.php?title=` for "vanilla" installations. * `namespaces` The ids of the Wikibase namespaces to synchronize with, separated by `,`. * `file` Path of where Oxigraph should store its data. You can then access it from your machine on port `7878`. No GUI is provided. ```sh # Make a query curl -X POST -H 'Accept: application/sparql-results+json' -H 'Content-Type: application/sparql-query' --data 'SELECT * WHERE { ?s ?p ?o } LIMIT 10' http://localhost:7878/query ``` ## Using a Docker image ### Display the help menu ```sh docker run --rm oxigraph/oxigraph-wikibase --help ``` ### Run the Web server Expose the server on port `7878` of the host machine, and save data on the local `./data` folder ```sh docker run --init --rm -v $PWD/wikibase_data:/wikibase_data -p 7878:7878 oxigraph/oxigraph-wikibase -b 0.0.0.0:7878 -f /wikibase_data --mediawiki-api http://some.wikibase.instance/w/api.php --mediawiki-base-url http://some.wikibase.instance/wiki/ ``` Warning: the Wikibase instance needs to be accessible from within the container. The clean way to do that could be to have both your wikibase and oxigraph_wikibase in the same [`docker-compose.yml`](https://docs.docker.com/compose/). You could easily build your own Docker image by running `docker build -t oxigraph-wikibase -f wikibase/Dockerfile .` from the root directory. ## License This project is licensed under either of * Apache License, Version 2.0, ([LICENSE-APACHE](../LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](../LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option. ### Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in Futures by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
