File Release Notes and Changelog
Release Name: TDB-0.8.0
Notes: The database format for TDB 0.8.0 is different and incompatible with TDB 0.7.X and before.
Changes: ==== 0.8.0 ** The on-disk file format has changed : datasets must be reloaded ** + TDBFactory now caches datatsets as they are created. Opening a dataset anywhere in the same JVM will return the same dataset. Closing this dataset immediately releases resources and closes the dataset everywhere in the JVM. + A named graph of <urn:x-arq:UnionGraph> is the RDF merge of all named graphs in a dataset. This is now supported as a graph name when accessing one graph in a dataset via the programmtic API calls. Update directly to the union graph is not allowed; update of any named graph wil be immediately visible in the union graph. + A named graph of <urn:x-arq:DefaultGraph> is the same as the unnamed graph in a dataset. + Upgrade to Java5 version of ARQ and Jena + Copes with spaces in URIs (strongly not recommended) + Internal general purpose (non-RDF) library code all moved under package "atlas" + Faster Turtle reader (combined underpinning with N-Triples bulkreader).
