Just because something is done in Cyc (or DBpedia, or Freebase, or SUMO, or ...) some particular way does not mean that it should be done in schema.org (or DBpedia, or Freebase, or ...) that way. This would be true even if the goals of Cyc (or ...) were very similar to the goals of schema.org (or ...). However, just because something is done in Cyc (or ...) in some particular way does not mean that it should *not* be done in schema.org (or ...) that way. I would hope that even if we think that the people behind Cyc are not giants that we can do better than otherwise if we stand on their shoulders (or maybe on their toes). The reason to have sub- and super-sports is to be able to talk about sports at different levels of granularity, letting content producers describe their information in a natural way but also letting content consumers extract the information that they need. There are lots of concepts that can benefit from this sort of treatment, from artistic genres to professions to cuisines. One reason to look at the precise details of how Cyc handles this representational meme is to see how a powerful representation formalism can provide support for many aspects of the meme. The Cyc-based solution can then be examined to determine better ways to support the meme in less-powerful formalisms. peter On 09/25/2014 07:28 AM, martin.hepp@ebusiness-unibw.org wrote: > > On 25 Sep 2014, at 16:08, Peter F.
