Is that true for the IPC standards? It has been a while since I looked into this, but I seem to recall being able to download anything I wanted from their site. Perhaps they make a lot available but some items they charge for. My recollection is that they had a superset spec which included standard Gerber type info along with mechanical and electrical information using an XML type format. It may have included other info as well but I'm not sure. I also recall that although they included lots of fields it would have been very easy to have missed some vital details and could take a fair amount of work to turn into a document you could actually design a CAD interface for. I mentioned using this standard once in one of the geda support groups and the replies were that no one likes XML because it is so wordy and hard to read. People talked about the design files bringing a system to its knees... lol! But it wasn't like anyone had the same idea of what they did like. Ten different responders had ten different ideas all the way from binary to... well, XML.
