SPARQL repository API and data model.

Provides a single, backend-independent API for working with SPARQL stores. Consumers query and write them through the Repository interface and exchange data as the SPARQL types defined here, layered on the RDF terms and statements of @metreeca/trio, regardless of which connector backs the store.

Media types

• SPARQLQuery — IANA media type for SPARQL query requests
• SPARQLUpdate — IANA media type for SPARQL update requests
• SPARQLResults — IANA media type for SPARQL query results in JSON

Repository

• Repository — a RepositoryClient with transactional execute and lifecycle close
• RepositoryClient — operations on an RDF store: ask/select/construct, update and merge/store

Data model

• SPARQL — query, update, or syntactic fragment as serialised text
• Dataset — RDF dataset overriding the one declared by a query or update
• Tuple — SELECT query-solution mapping
• Pattern — triple pattern admitting variables
• Variable — allocated ?-prefixed SPARQL variable

Factories

• sparql — mark a string or a template literal as SPARQL text
• tuple — construct a Tuple
• pattern — construct a Pattern
• variable — construct a Variable

Wrappers

• createBufferingRepository — wrap a Repository to batch a transaction's writes into few requests
• createLoggingRepository — wrap a Repository to log each operation and its elapsed time
