And it's pure python, nothing zope or zodb specific about it (of course the zodb backend requires zodb...) We've been working to tweak the various backends to be as efficient as possible. For example, the ZODB backend only stores the variably sized source, relationship type, and target identifiers once, and after that uses integers to refer to subsequent references. http://rdflib.net/ -Michel _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
