The Web3 Platform implementation of SPARQL imposes a few restrictions on the general SPARQL query language.
| 1. | Supports SELECT query form only
The current implementation does not support the CONSTRUCT, ASK or DESCRIBE query forms described in the SPARQL specification. |
| 2. | Predicates cannot be bound to a variable
A query containing a triple pattern such as x:foo ? x:bar is not supported |
| 3. | Querying named graphs with the GRAPH construct is not supported
The Web3 platform has no construct that maps to the concept of the named graph in RDF so this feature is not available through the query language. |
