Hi guys, just to clarify: my intention is not to encourage everyone to wildly mint URIs in namespaces they don't control (shiver...), and neither to accumulate all possible conference data at data.semanticweb.org (the dogfood site). The point was this: _if_ you would like your data to be incorporated into the dogfood site, then it should have dogfood namespace URIs, otherwise we cannot serve it. We hope to offer people who want to contribute to the site some advantages, such as: - taking away the burden of RDFising your data - not having to worry about serving the data after you have produced it - a stable service with a long-range commitment (as Daniel already said) - data integration across events through people and organisations - the possibility to let the community add to the data (in the form of SIOC discussions) - a UI that, while it can always be improved, is tailored for the domain of its data If that sounds appealing, then people can avail of those services in the way I outlined earlier in this thread. Apart from that, I agree with what Giovanni says below! If people are already serving their data and are happy with it, then there is no need to duplicate it onto the dogfood site!
