Title: [ANN] XQuery in the Browser, JavaScript Edition
This is a pretty exciting development. We discussed it at the W3C
Forms WG meeting and are looking forward to some experiments with
XForms and XQuery together. We already have a plan to recommend
XPath 2.0 for XForms 1.2 (advancing from XPath 1.0), and a working
XQuery superset is even better news.
If we could get XForms and XQuery together -- and more importantly,
if we could get them together in today's desktop browsers -- there
would be a great benefit on the web.
There are a few implementations of XForms done in JavaScript now;
among those listed at
http://www.w3.org/MarkUp/Forms/wiki/XForms_Implementations I think
it like that both Ubiquity XForms and AgenceXML XSLTForms are in a
position to experiment with this. In fact, Claudius Teodorescu has
already done one integration with the plugin version of xqib.
Looking at a few of the samples you've shown in XQIB with an XForms
implementation, I think that there are things that XQuery is great
at, and some where XForms is better.
Here's an example:
http://xformstest.org/klotz/2011/01/xqib-comparison/wx/
which is a re-casting of
http://www.xqib.org/js/WeatherREST.html
Note that the XForms version is markup-heavy and the XQuery version
is script-heavy. The UI part of the XForms version is pretty well
separated from the presentation version, though a few hacks are used
to provide for conditional presentation of info (it's a little hard
to display the Zeus image when none of the other conditions match).
XForms 1.2 should make this part smoother.

Dear all,
Last year, at XML Prague 2010, we presented our
latest release of the XQuery in the Browser plugin. While the
audience seemed enthusiastic about this idea, using a plugin
was seen as insurmountable obstacle to a wider adoption of
using XQuery on the client layer.
So we decided to get rid of the plugin.
It is our pleasure to introduce an alpha preview
of XQuery in the Browser, JavaScript Edition. The principle
remains the same: the XQuery code put inside a script tag
(type text/xquery) gets executed. The difference is: there is
nothing to install.
A preview of some samples is available under http://www.xqib.org/js
More information (supported browsers, how to
write your own XQuery code
) is available under http://www.xqib.org
Your feedback is welcome.
Kind regards and happy new year,
Ghislain
