Today's search interfaces typically offer keyword searches and facets for the retrieval of cultural heritage multimedia objects. Facets, however, are usually based on a static set of metadata fields. This set is often called an indexing profile. Graph-based repositories based on predicates about resources allow for more precise semantics. They offer stronger support for retrieval, and they can be adopted to almost any metadata format. Technically, those predicates may be serialized as RDF triples, but handling a huge amount of objects with numerous predicates puts an unpredictable load on the query engine. In this paper, we present an approach on analysing transition paths in the RDF triples at ingest time and using the results to create facets in the search index.
