  1. def retrieve (entityDesc: EntityDescription, entities: Seq[String] = Seq.empty): Traversable[Entity]

    Retrieves entities from this source which satisfy a specific entity description.

    Retrieves entities from this source which satisfy a specific entity description.

    entityDesc

    The entity description

    entities

    The URIs of the entities to be retrieved. If empty, all entities will be retrieved.

    returns

    A Traversable over the entities. The evaluation of the Traversable may be non-strict.

  18. def retrievePaths (restrictions: SparqlRestriction = SparqlRestriction.empty, depth: Int = 1, limit: Option[Int] = None): Traversable[(Path, Double)]

    Retrieves the most frequent paths in this source.

    Retrieves the most frequent paths in this source. Implementations are only required to work on a best effort basis i.e. it does not necessarily return all paths in the source. The default implementation returns an empty traversable.

    restrictions

    Only retrieve path on entities which satisfy the given restriction. If not given, all paths are retrieved.

    depth

    Only retrieve paths up to a certain length. If not given, only paths of length 1 are returned.

    limit

    Restricts the number of paths to be retrieved. If not given, all found paths are returned.

    returns

    A Traversable of the found paths and their frequency.
