Introduction
AllegroGraph provides support for SPARQL 1.1:
- Query,
- Update,
- Federated Query,
- Results in JSON Format,
- Results in CSV and TSV Formats,
- Results in XML Format
It does not directly support entailment regimes but AllegroGraph's RDFS++ reasoner or OWL Materializer can be used to support inference.
Note that AllegroGraph does not support either the Service Description or the Graph Store HTTP Protocol. All of the functionality in the Graph Store protocol can be achieved using SPARQL Query and Update).
DAWG test failures
- AllegroGraph encodes numbers and dates directly rather than storing them as strings. This means that the following literals will all encode the same way:
"+1"^^xsd:integer,"1"^^xsd:integer, and"0001"^^xsd:integer. DAWG tests that rely on non-canonical values being able to round-trip will fail.
If you find any other problems (with conformance or performance) please let us know by e-mailing support.
