That actually makes this discussion clear to me for the first time; and now that I understand it I know where I stand. IMHO, the difference between metadata and data is mostly in interpretation and solely in the information retrieved. That is, the format of information returned should be independent of the protocol used to retrieve it. We do not have and should not have separate schemes for separate times of information. Separate protocols for metadata and data is like separate protocols for JPEGS and text, or XML and protobufs. Data formats should be network transport independent. Network protocols should be data format independent. I'm not sure if that's an explicit principle of the Web architecture. It may have seemed so obvious that no one thought to state it, or realized they were relying on it. However it most certainly is a strong characteristic of layered network protocol design. -- Elliotte Rusty Harold elharo@metalab.unc.edu Refactoring HTML Just Published! http://www.amazon.com/exec/obidos/ISBN=0321503635/ref=nosim/cafeaulaitA
