[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: XML-enabled databases, XQuery APIs
 Understood. None of us speak for our companies unless we say we do and even then, we don't because that is what the Public Access Officers do and we ain't them. ;-) To sum up: 1. A binary format for any XML is best implemented by having schema-valid XML. D'oh but interesting. 2. A binary used for internal dbms representation is not likely to be interoperable. Broadly, a binary for ANY document type specific representation isn't likely to be interoperable and any general representation isn't likely to be efficient. So evolution tends toward application-specific binaries and each application language specification specs it'w own. A dbms binary IS an application-specific binary and one doesn't get the kinds of agreements in the dbms space as one does in other application spaces (say, rendering clients). 3. A binary encoding for a client side application has to be parsed and transformed into the dbms local binary if it is stored there. If we try to store an application binary in the dbms XML datatype, we are back to middleware. We can use XQuery on the server to get these hunks, but that is as efficient as the XML is 'query-nice', meaning, as amenable as the application structure is to querying (I might fetch an X3D indexed face set from it, but likely I would grab the Transform out of the scene graph because it has an ID and it returns a bunch of other good stuff). The use of application binaries to get performance complicates things, and yet, we will have them. len From: Michael Champion [mailto:michaelc.champion@g...] On 4/18/05, Michael Champion <michaelc.champion@g...> wrote: > > That's our position. By that I mean it's my position, and I think it's Michael Rys position. I don't speak for MS in any official capacity on this, and our minds are wide-open to actual evidence that a standard binary XML format could be fast, small, support XQuery, be better for SOAP than XML is, support generic well-formed XML somehow, and do all that well enough to make the disruption worthwhile. ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://www.oasis-open.org/mlmanage/index.php>
