More browsers for ISWC 2010 data?

2010-11-07 Thread Jie Bao
Hi all, I added a few known data browsers that can work with ISWC 2010 data [1]. If you know other live demos that can browse/visualize the dataset, please expand the list, or let me know. [1]

+1 indeed. Content-Location has definitely been overlooked. During conneg, it is used to differ between a resource and its representation(s), which are obviously different resources (well, not necessarily the same). This distinction could certainly be enough to remove the fundamental need for

Hi Toby! For your information, the term EON is also used as the acronym of the International Workshop on Evaluation of Ontology-based Tools, an (almost-) yearly event that exists since 2002. See [1] for the proceedings of the first EON workshop. It would probably not be advisable to reuse the

Hi John! I understand your points. I also don't think that 303 is a poor solution in any fundamental way. In fact, given the use-case you described, having a stable URI which delegates to the current location is perfectly fine, and in many cases preferable to the alternative (demanding

Hi John Your points are good ones and some care should certainly be taken in how a possible 200-with-content-location option should be presented to the 'outside world'. 1) the public-lod forum is mostly aimed at practitioners, so hopefully not too many new LODers will have been alarmed by the
