Jerome:
Hmmm … not sure I understand the question.
The content you create (and generate) are already in the Alfresco repository, albeit in a different store type that provides Subversion-style
versioning behavior (file and dir versioning, branching, snapshotting, etc.).
To have web pages that dynamically query the repo to source web
content, you can use either our native Java API for the AVM (the
Subversion-style repo implementation) or, with 2.1, simply use the
Javascript / Templating API (in conjunction with web scripts).
For a dynamic form element, you can use an inline callout by referencing
a JSP that fetches a list of current users and puts that back into the
form. To do this, your JSP actually generates part of your XSD, which,
when done, we in turn generate into the browser-based XForm your
users use to create or mod content.
You can find an example of the JSP in-line callout in our sample website
(which is a bit long-in-the-tooth and getting updated, but is still useful
to demonstrate this).
Let us know if you've further questions.
