My knowledge of the W3C XML Query Working Group would tend to suggest that XUpdate is not in consideration, though it's been months since I paid any attention to their mail list. They're very far along in their process and the W3C does not typically take open source projects under their wing given that it's a vendor consortium and this would require that a specific vendor champion XUpdate. It's possible, but pretty unlikely. As for there being only one query and manipulation language, I understand the argument but I don't agree. XQuery is essentially SQL shallowly wrapped in XML garb, as the W3C WG has been lobbied hard by the database companies represented there. If you look at it you'll realize it's not really XML at all, except as a shell for SQL statements. I know a few people at Sun who consider it a complete failure in terms of *being* XML. It requires a specialized, non-XML parser. If you were Oracle or some company that already had a SQL database implementation, you'd be happy with XQuery. XUpdate by comparison is actually XML syntax, was designed with a smaller footprint in mind. It's a lot easier to deal with in terms of both implementation and documentation. And yes it has fewer features. There's certainly room for both of these approaches, and losing one of them would lose one valid approach (the heavyweight, SQL approach vs. the light- weight XML approach) to database updates. There's also XSLT itself as a mechanism for manipulating XML database content. > ----- Original Message ----- > From: "Murray Altheim" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Tuesday, December 18, 2001 12:25 PM > Subject: Re: XQuery in dbXML > > > Marek Mosiewicz wrote: > > > > > > I have recently found dbXML and I think it is great idea to have open > source > > > XML database.
