Re: [Exist-open] XQuery Update Facility 1.0

[Adam R. <ada...@de...>]

We already implement something similar, this was done some time ago and =
really needs to be bought inline with the current specification. However =
if you dont mind the syntax differences (not huge), then this is useable =
today - http://www.exist-db.org/update_ext.html

Subject: [Exist-open] XQuery Update Facility 1.0

Just curious as to how close eXist is to the impending W3C update =
extensions?=20
=20

....A

-----------------------------------

The W3C XML Query WG published the following documents as Last Call WDs =
early=20

last week:

        XQuery Update Facility 1.0
       http://www.w3.org/TR/xquery-update-10/

        XQuery Update Facility 1.0 Requirements
       http://www.w3.org/TR/xquery-update-10-requirements/

        XQuery Update Facility 1.0 Use Cases
       http://www.w3.org/TR/xquery-update-10-use-cases/

The XQuery Update Facility abstract says:

        "This document defines an update facility that extends the XML =
Query=20
language,         XQuery. The XQuery Update Facility provides =
expressions=20
that can be used to         make persistent changes to instances of the=20
XQuery 1.0 and XPath 2.0 Data         Model." =20

The XQuery Update Facility adds 4 new updating expressions to XQuery =
1.0;=20
insert, replace, rename, and delete. These expressions modify instances =
of=20
the XQuery 1.0 and XPath 2.0 Data Model (XDM). The XQuery Update =
Facility=20
also adds a non-updating expression, transform, which returns an XDM =
instance=20

that has been created by copying existing XDM instances and then =
modifying=20
them.

The review period for these Last Call WDs ends on Oct. 31, 2007. The =
status=20
section of each document specifies how you can provide comments to us.
