Dear Richard, > Multiple popular vocabularies that use this practice have been listed > in the thread. I have seen those. I still think this is rather anecdotal in comparison to the very large set of properties that has a hasXXX OR a isXXXBy that one can found in the wild. Doing a quick search on LOV confirms me this. > That's a convention coming from Description Logics that I haven't > seen in any other modelling school. Don't count on me to fuel any religious wars. I don't care where does it come from and I don't think it matters. I'm not myself feeling part of the DL school (as I suspect many) and I still model my vocabularies this way. > I'm with TimBL on this one: > > [[ On the other hand, also one should not encourage people having to > declare both a property and its inverse, which would simply double > the number of definitions out there, and give one more axis of > arbitrary variation in the way information is expressed. ]] > http://dig.csail.mit.edu/breadcrumbs/node/72 I fully agree with this too, but this is really an orthogonal issue. I'm not saying that one should model both a property and its inverse in the same ontology. I'm saying that when the ontology engineer has chosen the direction of the property he wants to model, then the label should convey this direction. Otherwise, the person who wants to re-use the property has to look at the domain and range, and not get confused of what is the domain and the range [as most of the people are, this is the same well-known problem that turning left/right with your car and there are many studies that show this :-)]. The hasXXX OR isXXXBy pattern fulfills this use case. I'm not saying again that you should have both in your ontology. I hope this is clear. Best regards.
