#configure(options = {}) ⇒ Object

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

Can configure the following values:

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

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

Parameters:

  • options (Hash) (defaults to: {})
