group-subjects clj

(group-subjects solutions)

index-triples clj

(index-triples db)

Return an indexed database of triples. Indexing a database will result in better performance if you want to run multiple queries over the same database.

All query functions should accept either a sequence of triples or an indexed database.

merge-dbs clj

(merge-dbs & dbs)

Merges all supplied Matcha databases together into one. Any individual database form can either be indexed already with index-triples, or a sequence of triples, in which case the triples will be indexed before being combined with any other databases.

query-var? clj

(query-var? sym)

Test whether supplied sym is a query variable. Query variables are symbols who's name begin with a ?.

triple clj

triple-vector->idx-triple clj

(triple-vector->idx-triple [s p o])

Assume triples are either 3/tuple vectors or can be destructured as such. Grafter Quad objects can be destructured in this manner.
