oxigraph/CHANGELOG.md

Master

Added

• SPARQL 1.1 Update support for Rust, Python and JavaScript. All store-like classes now provide an update method.
• SPARQL 1.1 Query Results CSV and TSV Formats serializers and TSV format parser.
• The SPARQL Query and Update algebra is now public.
• The stores are now "graph aware" i.e. it is possible to create and keep empty named graphs.
• A simple built-in HTTP client. In the Rust library, is disabled by default behind the http_client feature. It powers SPARQL federation and SPARQL UPDATE LOAD operations.
• std::str::FromStr implementations to NamedNode, BlankNode, Literal, Term and Variable allowing to easily parse Turtle/SPARQL serialization of these terms.
• Optional Sled storage for oxigraph_server.

Removed

• The default_graph_uris and named_graph_uris parameters from pyoxigraph query methods.
• Python 3.5 support.
• (Memory|RocksDB|Sled)Store::prepare_query methods. It is possible to cache SPARQL query parsing using the Query::parse function and give the parsed query to the query method.

Changed

• Fixes evaluation of MONTH() and DAY() functions on the xsd:date values.
• Variable::new now validates the variable name.
• (Memory|RocksDB|Sled)Store::query does not have an option parameter anymore. There is now a new query_opt method that allows giving options.
• xsd:boolean SPARQL function now properly follows XPath specification.
• Fixes SPARQL DESCRIBE evaluation.

[0.1.1] - 2020-08-14

Added

• The "sophia" feature implementing the sophia_api traits on Oxigraph terms and stores.
• Explicit types for quads iterators returned by stores.

Changed

• QueryOptions::with_default_graph now takes an impl Into<GraphName> instead of an impl Into<NamedNode>.
• QueryOptions::with_named_graph now takes an impl Into<NamedOrBlankNode> instead of an impl Into<NamedNode>.
• pyoxigraph query methods now takes two new parameters, default_graph and named_graphs. default_graph_uris and named_graph_uris parameters are deprecated.
• Fixes a bug in xsd:gYear parsing.

[0.1.0] - 2020-08-09

Added

• QueryOptions now allows settings the query dataset graph URIs (the SPARQL protocol default-graph-uri and named-graph-uri parameters).
• pyoxigraph store query methods allows to provide the dataset graph URIs. It also provides an option to use all graph names as the default graph.
• "default graph as union option" now works with FROM NAMED.
• pyoxigraph now exposes and documents Variable, QuerySolution, QuerySolutions and QueryTriples

[0.1.0-rc.1] - 2020-08-08

Added

• oxigraph Rust library with SPARQL 1.1 query support and memory, Sled and RocksDB stores.
• oxigraph_server standalone SPARQL server.
• oxigraph_wikibase standalone SPARQL server loading data from a Wikibase instance.
• pyoxigraph Python library based on Oxigraph.
• oxigraph NodeJS library based on Oxigraph.
