sem:in-memory-store

sem:in-memory-store(
   $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.

Parameters
$dataset A set of triple values representing the dataset for the store.

The results from a SPARQL construct query or call to sem:rdf-parse() can be used directly as the value for this argument.

sem:store() :  Use the value to pass into a function that
requires a sem:store (like sem:sparql-update).
