If you never export as RDF, what's the harm? You just get some unexpected pages in query results. MFU: That's right. If you care about semantics, then you care about wrong query results. I care about semantics, which is why I'm using a semantic wiki. -- Uschold, Michael F wrote: > I'm now getting this.

Good point. That help on categories seems to predate their strict representation in SMW's RDF Export. I changed the help documentation: * http://ontoworld.org/wiki/Help:Annotation#Categories no longer endorses, and mentions inconsistencies. * http://ontoworld.org/wiki/Help:RDF_export#The_exported_data_in_detail explains how categories are exported. MFU: thanks, that is good. -- > If you use [categories] differently, then bad things will happen when > the translation to RDF happens, and when hierarchical inference > occurs, What external program are you using that does hierarchical inference, and what "bad things" happen? (Does it blow up like the computer in http://en.wikipedia.org/wiki/WarGames :-) ) MFU: by bad things, I mean wrong inferences. I'm not actually doing this external inference, but one could ih principle. -- =S Page ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
