Enhance UX of adding new predicate

[edmondchuc]

As mentioned in #3, an enhancement will be to allow for the user to select well-known predicates using an autocomplete select field. The source of this can either be from a local source or from a well-known online source.

Sources should implement full-text search, similar to a prefix lookup service. Prefixes and labels should be indexed to allow for users to enter values such as:

• skos:prefLabel --> http://www.w3.org/2004/02/skos/core#prefLabel
• prefLabel --> http://www.w3.org/2004/02/skos/core#prefLabel
• preferred label --> http://www.w3.org/2004/02/skos/core#prefLabel

This implementation may be applicable to other similar scenarios such as adding new object values that are IRIs using the dash:InstancesSelectEditor.

The SHACL UI component should allow for the source to be configurable as a URL.

We will need to define an API search + response schema.

• Request
  • query parameter q - user search term
  • Example: skos:prefLabel
• Response
  • JSON response

    • {
          "value": "http://www.w3.org/2004/02/skos/core#prefLabel"
      }
