    • isValidClassURI

      boolean isValidClassURI(String uri)
      Verifies that @param uri is valid (Has correct class prefix)

    • isValidPropertyURI

      boolean isValidPropertyURI(String uri)
      Verifies that @param uri is valid (Has correct property prefix, and connecting text)

    • isValidMembershipURI

      boolean isValidMembershipURI(String uri)
      Verifies that @param uri is valid (Has correct membership uri)

    • mapClassToType

      String mapClassToType(String uri)
      Maps an rdfs class uri to a GraphQL type Return null if URI is invalid (not a class URI)

    • mapTypeToClass

      String mapTypeToClass(String type)
      Maps a GraphQL type to an rdfs class uri

    • mapPropertyToField

      String mapPropertyToField(String uri)
      Maps an rdf property URI to a GraphQL field Return null if URI is invalid (not a property URI)

    • mapPropertyToType

      String mapPropertyToType(String uri)
      Maps an rdf property URI to a GraphQL type Return null if URI is invalid (not a property URI)

      String mapFieldToProperty(String type, String field)
      Maps a GraphQL object type and field to an rdf property URI

    • getJsonIDKeyPrefix

      String getJsonIDKeyPrefix()
      Returns:
      the prefix used by the id key in the expected json.

    • getJsonObjectKeyPrefix

      String getJsonObjectKeyPrefix()
      Returns:
      the prefix used by object keys in the expected json.

    • getJsonScalarKeyPrefix

      String getJsonScalarKeyPrefix()
      Returns:
      the prefix used by scalar keys in the expected json.

    • removeJsonKeyPrefix

      String removeJsonKeyPrefix(String key) throws org.apache.jena.atlas.json.JsonException
      Returns:
      the json key without its prefix. Works for keys with the defined prefixes from this current config (id,scalar,object)
      Throws:
      org.apache.jena.atlas.json.JsonException - if the provided @param key did not have one of the pre-defined prefixes.
