h2. Materialisation

An A GraphDB repository will use the configured rule-set to compute all inferred statements at load time. To some extent, this process increases processing cost and time taken to load a repository with a large amount of data. However, it has the desirable advantage that subsequent query evaluation can proceed extremely quickly.
Apart from a number of optimisations, the approach taken by GraphDB is one of 'total materialisation', where the inference rules are applied repeatedly to the asserted (explicit) statements until no further inferred (implicit) statements are produced.
