Well, I'm sure it's inconvenient, but this is probably a good reminder to everyone that apps can always be made more robust. Having a local schema cache is a good idea. I think also having some habits around PGP-signing of schemas so that authentic copies can be picked up from directories and registries would be a healthy thing for us all to be doing also. I always used to PGP sign the FOAF schema document and point to it with a wot:assurance link. This got a bit fiddly when I set up content negotiation so I didn't keep up with the practice for a while, but I reckon it's worth doing. Then maybe schema and app authors can sign each other's keys at SW conferences etc., to allow some basic checking of schema copies that are bundled with apps... cheers, Dan -- http://danbri.org/
