SPARQL.Client is a SPARQL protocol client for Elixir.
It executes all forms of SPARQL queries against any SPARQL 1.0/1.1-compatible endpoint over HTTP and supports result sets in both XML, JSON, CSV and TSV formats, with JSON being the preferred default for content-negotiation purposes.
Graph results from
CONSTRUCT queries can be read in any serialization format supported by RDF.ex and will be directly deserialized to the respective RDF.ex data structure.
The major function of the SPARQL.Client is
SPARQL.Client.query/3, which performs the various forms of SPARQL queries. It takes a SPARQL query string, a SPARQL endpoint URL, and some options. The query is only sent to the endpoint if it is syntactically valid. Depending on the query form either a
SPARQL.Query.Result struct or an
RDF.Graph is returned.
For a more detailed description, including the various
SPARQL.Client.query/3 options, see the API documentation.
