XQuery 1.0 and XSLT 2.0 are now in Candidate Recommendation

mrys — Thu, 03 Nov 2005 21:14:00 GMT

Finally, after 6 years of hard work, the W3C has released the Candidate Recommendation specs for XQuery 1.0, XPath 2.0 and XSLT 2.0. Does this mean that the recommendations are done? No, not yet. But it means that we reached an important milestone. Now everyone is officially invited to implement the specs, run the test suite, and provide feedback. Within the next couple of months, we will see which ones of the features will have at least two implementations with the same result and what may be underspecified or will not find an implementation.

Since we now ship SQL Server 2005 with its XQuery subset and are planning the next release, I would like to encourage you to check out the XQuery specs (including the Full-Text specs) and let me know what functionality you want us to implement with the highest priority in the next release of SQL Server.

New XQuery and XSLT Working Drafts: We are making progress!

mrys — Sat, 17 Sep 2005 01:21:00 GMT

The XML Query and XSL Working Groups have released the following Working Drafts of XML Query 1.0, XSL 2.0, XPath 2.0 and supporting documents. The goal of this release is to permit public review of changes made in response to Last Call comments. These documents are very close to the so called Candiate Recommendation that we hope to be able to publish soon. Yeah! We are making progress! Even though my issue with the spec has been closed without making the proposed change (minority opinion, here I come)...

Also published are the following updated Working Drafts which have not yet reached Last Call:

Comments are as always welcome through the W3C's Bugzilla interface or the public comment mailing list.

PS: Thanks to the editors and especially Norm who again did a terrific job on getting the docs ready...

Channel 9 and Ken North Videos

mrys — Mon, 29 Aug 2005 03:08:00 GMT

I am back from vacation (no shark encounter :-)). I had a good time and have much more photos and dive reports to upload.

While I was gone, Robert Scoble and Channel 9 published the video they took in my messy office before I went on vacation to give you your XML and SQL Server 2005 fix while I was gone :-). We chat about XML, SQL Server, my role as a program manager, security and XML etc. I also include some simple demos.

Also, Ken North published two videos he taped during the town hall meeting during the XML 2004 conference last year.

Enjoy!

XQuery1.0/XPath 2.0 needs your help!

mrys — Wed, 13 Jul 2005 10:03:00 GMT

As I mentioned earlier, XQuery 1.0/XPath 2.0 has still one last call issue that that can benefit from user input. Basically, the question is, whether the so called value comparisons (that use the Fortran style syntax eq, lt, ge etc) should behave the same when encountering untyped values as the general comparisons (the XPath 1.0 aligned =, <, >= etc. that provide implicit existential quantification) or whether they should treat the untyped values always as strings.

For more information and how you can help, please continue here....

StylusStudio interviews me

mrys — Mon, 28 Feb 2005 23:09:00 GMT

StylusStudio, in their ongoing series of interviews interviewed me a couple of weeks ago and have now published it on their website. And I received the opportunity to plug SQL Server 2005, my co-authored XQuery book and my weblog :-). Thanks to the folks at StylusStudio to invite me and to Larry Kim for getting the interview done...

One nitpick that I missed when I proofread it: SQL/XML is part 14 and not 13 (not that anyone would care :-)).

Posts related to XQuery and its Type System

More will follow which I will add to this post, so please check back frequently.

Posts on XML Schema

Here are my musings on XML Schema (only the ones I have written down so far :-)):

Is XML Schema usable as a type system?
How to evolve XML Schema collections in SQL Server 2005
The XQuery Type System is based on XML Schema
How XML Namespaces and XML Schema relate (no, they are not the same!)

Welcome to my work related blog site

mrys — Wed, 09 Jun 2004 06:11:00 GMT

I decided to finally join the http://blogs.msdn.com community. However, I will contine to mainly blog at http://sqljunkies.com/weblog/mrys and only syndicate the work-related entries on SQL Server, XML Standardization, XQuery, and other XML Technologies here. Until I can do this automatically (I have bugged Scott many times already to add the feature to automatically republish an RSS feed), I will post a short synopsis with a link here and request people to comment on the sqljunkies site.

Over the next few posts, I am going to send topically aggregated summaries of already published article.

Feel free to contact me if you want me to write about something related to the topics above.
