get xFeed package if you want xFeed ;)

A couple people noticed that xFeed and AJAX enhancements required for xFeed are not yet included in the "full" package. To be fixed rsn, but until then please get the "xFeed subset" if you are interested in techniques demonstrated in the zip code demo http://www.xfeedme.com/zip/zipcompletions_async.html

xsdb/xFeed AJAX release

The xFeed example application of the xsdb package provides an infrastructure which makes it easy to implement "type ahead suggest" drop down selections matching against large or small data sets. The xFeed example illustrates how the xsdb framework can simplify data management and transmission in real applications.
See http://xsdb.sourceforge.net for additional documentation and http://www.xFeedMe.com for live web page examples. Most of the package bulk consists of example data used in the example configurations.

xsdbXMLcs gets dinky patch for mono compatibility

xsdbXMLcs.ContextContainer required
a two line patch to make the self tests
check out when run under mono 1.0.6.
I reported it as a mono bug
(the mono version of System.IO.Directory.Exists
raises an error in some cases where
MS .NET returns false). Get the patch from
cvs if you need it for now.

There is a new release of xsdbXML which provides
a native java port of the framework in addition to
bugfixes for the C# and Python implementations.
All three implementations are completely independent
and pass the same test cases.

infrastructure to allow tabular data to be published,
retrieved, and combined over the Internet.

sourceforge glitch -- wrong file download

For a few days sourceforge was downloading an old file as the latest release. I didn't notice because the reported file size was correct (even though the file delivered was smaller). Please get it again if you got the latest release.

win32 binary query exe download

In response to a number of requests, I've added a binary distribution which provides a Win32 line-mode interface to the xsdbXML query functionality for people who don't want to install or upgrade Python. I created it using the the cx_Freeze program available from http://starship.python.net/crew/atuining.

auto generated crud removed from zip

I removed a tremendous amount of autogenerated stuff from the zip file, sorry I didn't notice it (that's the problem with broadband :( ). If you want it back you can regenerated it from what remains. Now it's 1/5 the previous size. Thanks for the helpful complaints!

xsdb does XML, SQL is dead as disco :)

xsdb does XML, SQL is dead as disco :)

The xsdbXML framework provides a flexible
and well defined infrastructure to
allow tabular data to be published, retrieved,
and combined over the Internet.

It's a little bit like the daughter of the Gadfly
SQL engine in the buff, on steroids. This is
a major departure from the previous releases
of xsdb.

Please read about it and download it from

xsdb declared beta

Because I've gotten enough positive feedback and the bug reports have died down. I'm calling xsdb a beta starting at the sound of the beep **beep**.

bugfix alpha file release uploaded

There are a lot of changes (mainly minor).
This release was motivated primarily primarily by the fast reconnect problem reported by
Wolfgang Lipp. See the revised api documentation
on making Connection objects.
