Apart from the subject of this discussion, I find such general statements very dangerous. The fact that the tools you develop do not require, or make use of, OWL DL isn't really a strong argument. There are other people (like me) relying on reasoning, which is easier to accomplish in OWL DL. Clearly, it is important to publish data even if it does not conform to OWL DL, but that doesn't mean that we shouldn't bother to get it "right" (hopefully in OWL 2). Also note that it is not important for the whole open web to be in OWL DL, but only those bits of it you need for a particular task. Kind regards, Jens -- Dipl. Inf.
