While examining the code today, I noticed that swo_core had incorrect ontology prefixes ‘swo’ and ‘swo2’ set to ‘http://www.ebi.ac.uk/swo/http://www.ebi.ac.uk/efo/swo/’. This error was only present in an obsolete term SWO_0000399 (I must have introduced a bug when I made that term obsolete). All instances of this incorrect prefix were removed. Additionally, SWO_0000399 was incorrectly written as SWO__0000399 (with two underscores), and this was also fixed. These fixes were committed at revision 258 of the sourceforge SVN respository.
