#configure(options = {}) ⇒ Object

API for configuring class properties on a RDFSource. This is an alternative to overriding the methods in this module.

Can configure the following values:

- base_uri (allows passing slugs to the RDFSource initializer
  in place of fully qualified URIs)
- rdf_label (overrides default label predicates)
- type (a default rdf:type to include when initializing a
  new RDFSource)
- repository (the target persist location to for the RDFSource)

Examples:

configure base_uri: "http://oregondigital.org/resource/", repository: :default

Parameters:

  • options (Hash) (defaults to: {})
