Martin,

 

I'll address your issues below...

 

Cheers!

I don't quite understand this.

 

What is Laszlo? Why would this benefit AT? Are you talking about making
changes to AT core (in which case you'll need to get buy-in from the wider
community and the release manager, of course)?

 

PAUL> Laszlo is a presentation server - it consumes an XML file and web
services and produces either an HTML or Flash interface.  I used to work for
a non-open source CMS company and while we had a portal API (just like
CMF/Plone) almost all customers wanted the presentation layer separate.
What we are proposing is concentrating on having a set of templates that
would produce the Laszlo XML as an add-on/plug-in/maybe as a fork.

Have you looked at the work going on in Bling and KSS?

 

PAUL> No, but if this being geared toward a 3.0 release of Plone it is a
little late for us.  We needed some of the event property registration stuff
yesterday.

This sounds fairly risky, and potentially overlapping with wider AJAX work

proposed for 3.0 in the shape of Bling and/or KSS.

 

PAUL> Perhaps, when we did some searching, none of these turned up, so if
you can pass me some URLS that explain that work, we would be happy to synch
up with them if the work is truly similar.  Perhaps we can accelerate its
release.

PAUL> It sounds to me like you're takling about introducing a dependency on
a

third-party system in AT - again, this sounds a bit suspect to me.

 

PAUL> Not at all; this would be just another way of rendering data - we will
not be replacing base_edit, or any of the other fundamental "templates", but
provide another set of templates that could be called.

 

PAUL> BTW, this email to this list is precisely a reach-out to the broader
community.  We will donate the code developed (which most certainly will not
be production ready for the Laszlo connectivity, but hopefully will be
production ready for the JavaScript events registration to the Archetypes
community and will also assist as we can in integrating with what the
broader community wants.  Basically view it as a set of volunteers out of
the woodwork that have seen a need and are working to fill it.
