AshR2RML.SPARQL.Protocol (AshR2RML v26.8.22)

Copy Markdown View Source

Read-only W3C SPARQL Protocol execution through SPARQL.Client.

SPARQL.Client also implements update operations, but this module deliberately exposes queries only. Verification capability never manufactures remote mutation authority.

Functions

query(endpoint, query, opts \\ [])
query_with(endpoint, query, opts, client_fun)
