Method: ShEx.execute

Defined in:

lib/shex.rb

.execute(expression, queryable, focus, shape, format: 'shexc', **options) ⇒ Operand

Parse and validate the given ShEx ‘expression` string against `queriable`.

Examples:

executing a ShExC schema

graph = RDF::Graph.load("etc/doap.ttl")
ShEx.execute('etc/doap.shex', graph, "http://rubygems.org/gems/shex", "")

Parameters:

• expression (IO, StringIO, String, #to_s) —

  (ShExC or ShExJ)

• focus (RDF::Term)
• graph (RDF::Queryable)
• map (Hash{RDF::Resource => RDF::Resource})
• shapeExterns (Array<Schema, String>) —

  ([]) One or more schemas, or paths to ShEx schema resources used for finding external shapes.

• options (Hash{Symbol => Object})

Returns:

• (Operand) —

  Returns operand graph annotated with satisfied and unsatisfied operations.
