arachne.aristotle.query — org.clojars.samirsa/aristotle 0.0.1-SNAPSHOT

build clj

(build query)

Build a Jena Operation object from the given query, represented as a Clojure data structure

parse clj

(parse query-str)

Parse a SPARQL query string into a Jena Operation

pull clj

(pull graph subject pattern)

Get all the properties associated with a subject using syntax similar to Datomic's Pull.

Cardinality-1 properties will be returned as single values, otherwise property values will be wrapped in sets. Graph must support OWL inferencing to make this determination.

run clj

(run & args)

Given a graph and a query (which may be either a precompiled instance of org.apache.sparql.algebra.Op, or a Query data structure), execute the query and return results.

Results will be returned as a sequence of maps of variable bindings, unless an optional binding vector is passed as the first argument. If it is, results are returned as a set of vectors.

Takes an optional final argument which is a map of initial variable bindings. This is how parameterized inputs are passed into the query.

sparql clj

(sparql op)

Return a SPARQL query string for the given Jena Operation (as returned from build). Useful mostly for debugging.
