DreamWorks Animation represents some of its working information about movies, scenes, etc. into an RDF (Resource Description Framework) store. RDF is more flexible than conventional relational databases, maintain an unstructured and constantly changing web of relationships between pieces of data. This lack of structure means that searching RDF can be slow. The team has developed an RDF store optimized for subsets of data where the structure is stable and well-defined (for instance, every scene is part of exactly one movie).
