sem.inMemoryStore

sem.inMemoryStore(
   dataset as sem.triple[]
) as sem.store

Summary

Returns a sem:store constructor that queries from the sequence of sem:triple values passed in as an argument. The sem:store constructor returned from this function will raise an error if it is passed as part of the options argument to a call to sem:sparql-update().

The default rulesets configured on the current database have no effect on a sem:store constructor created with sem:in-memory-store().

This should be used along with sem:sparql() in preference to the deprecated sem:sparql-triples() function. We will remove documentation of sem:sparql-triples(), but leave the function for backwards compatibility.

This function is a built-in.
