Re: Data Virtualization

Hi Achim, et al.,

Well thank you, sorry to be so far behind on things, only reading the email
titles for a while.

I presume everyone is aware of Orbeon which has a J2EE server that connects
to SQL sources and uses their XPL spec that XProc superceeded. So, the
concept is proven, if in another context, for some time commercially.

The other piece of the puzzle is DFDL, as you likely are aware, the schema
based binary file de-serializer.

Put it all together and there's nothing that could not be done by markup.
The problem, I suppose is the apparent widespread dislike of it .

Well, thanks again for all your efforts.

Hi Hank,
welcome to this list.

there are some solutions using REST with XProc I know of. As Christoph
said, I showed one of them at XML Prague. It is based on a implementation
of and
The original implementation of the WebApp specification using XMLCalabash
is by Florent Georges is .

XMLCalabash itself has of course Piperrack, which is a web server for
running XProc pipelines. Also based on XMLCalabash is Conal Tuohy project
XProc-Z (

Looking forward to hear how your project develops.

Greetings from Germany,

if you have seen some of these Hibernate queries it's obvious there's some
backflips to create the right json for some front end UI.
