No. This is not true. Thomas was quite clear that they do not have a contract with their data supplier, in this case a government agency. They are receiving critical data from this agency, but they have no contract with it and and no ability to tell them what to do or charge them for anything. Possibly they have a contract with a downstream client, but their upstream information provider is in no way under their control or influence, contractual or otherwise. This is the world we have to deal with. This is the world envisioned by the semantic web. We exchange information without contracts or agreements. Some people say we should do this with RDF. Some people think plain XML will suffice. But the old style model of contracting, negotiating, and/or agreeing to everything in advance has hit its limits. The complexity of prenegotiating data formats is at least linear in the number of parties who have to communicate, with a big hefty constant multiplier provided by your friendly lawyers. This model is as outmoded as subscribing to every magazine and newspaper you want to read and having a stack of dead trees dropped your doorstep each morning. -- Elliotte Rusty Harold elharo@m...
