It is time to remind ourselves of what James Gosling figured out in 1990. A successful standard needs to wait until there's some actual experience in the field being standardized. <http://java.sun.com/people/jag/StandardsPhases/> You don't want to standardize until you understand the problem domain, and have seen multiple, competing possibilities. XQuery is not even finished yet. There's virtually no experience in the community with any XQuery APIs. It is far too early to be thinking about any sort of standard XQuery API. IBM. Oracle, and anybody else who wants to should go ahead and design XQuery APIs so we can learn from them and use them. However, they should not yet attempt to standardize these. Any API designed at this early time is guaranteed to have flaws, both errors of omission and commission. We simply don't know enough to do better. Standardizing now would just lock in these inevitable mistakes. This JSR should be rejected in toto. None of this should be seen as preventing Oracle and IBM from working on XQuery APIs. However, before we establish any API as *the* XQuery API for Java, we need to have at least a year or two's worth of actual production experience with different XQuery APIs so we can learn what works and what doesn't, and what should be standardized and what shouldn't. -- Elliotte Rusty Harold elharo@m...
