Hi, as others may be interested in this discussion, I am also including xesam (= the ontology developers list)
I was a bit slow to answer, sorry. Tomás - what are you programming? do you have a url or a blogpost about your work? nao:Tag is for systems that just use NAO/NIE and are fine with no-brainer solutions. a nao:Tag has the semantic meaning of : the tag is a string. its unique. pimo:Tag is for systems that want to achieve a highlevel integration of Addressbooks, Calendars, Websites, etc... into a semantic network. pimo:Tags are then not only tags, but can be also a pimo:Person - that is, you can use a person's name to tag something but - surprise - it is also a person. now clicking on the person will get more... a pimo:Tag has the semantic meaning of : the tag is a unique string which is also a Thing out of the real world which can have more attributes. I also documented this here in the FAQ https://sourceforge.net/apps/trac/oscaf/wiki/PIMO/FAQ#Whatisthedifferencebetweennao:Tagandpimo:Tag best Leo It was Tomás Vírseda who said at the right time 12.09.2009 23:50 the following words: > Hi, > > I'm confused about pimo:Tag and nao:Tag classes described in their > respective ontology.
