Release Notes: This release introduces a new general purpose tool, rdfDiff, that can be used to take the delta of two sets of triples in RDF Patch format. This release also configures logging in Haruhi to suppress the torrent of INFO messages generated by the Spring framework.
Release Notes: To prepare for applications with complex options, the Centipede version has been bumped to 98.7. The Main app has been switched to use Spring and classpath scanning to find applications, which takes a step out of creating an application and means new apps can be added by just adding classes to the classpath.
Release Notes: This release changes the organization of :BaseKB Now in that literals go into a file called literals #86 and predicates with a double dot (which are said to be erroneous) go into the dotdot file #87. Internally work has continued on the use of the set difference operator to validate Freebase data #83 and #70.
Release Notes: Major changes include #79 (set difference operator) and certain work towards #70 (extraction of unique predicates, subjects and objects), as well as #78, which sets the correct jar versions for the "haruhi" script and makes haruhi look for the same version of bakemono as itself.
Release Notes: The centipede framework has been removed from Infovore, as well as the aborted chopper project. This version is a cleaned-up version of the software which has processed Freebase without a hitch for several weeks.
