Corporate Memories are computer systems in organizations that continuously collect, update and structure knowledge for various tasks.
The
Resource Description Framework (RDF) is commonly used to represent such knowledge, which is stored in quadstores as subject–predicate–object–graph quadruples.
Since typical RDF stores lack crucial features for enterprise scenarios, we propose an initial version of a tailored quadstore as part of a larger system called ATIC.
Our implementation in this demo paper comprises RDF management with an
SQLite backend, Discretionary Access Control on graphs and resources, confidence-attributed triples, change tracking with
RDF patches and a virtual graph for accessing a file hosting service via RDF.
This is accompanied with a server component providing endpoints and corresponding frontends.
Results of a preliminary evaluation verify the correct operation of our prototype and indicate moderate performance.
