Bojan, can we confirm if 1-3 will be sufficient in the face of improving the
REST webapp to use Spring REST instead of EntityBroker?

webmvc folks, this is where I think you might be of assistance, looking at
these REST API parts 1-3 above (see
https://wiki.duraspace.org/display/DSPACE/REST+API) and the proposal around
a Javascript Based User interaction. Can you comment on if/where you feel
that there is overlap with the Spring Controllers/Actions your creating in
the webmvc project, specifically, we want to consider if we are talking
about the same Controllers in both the REST and WebMVC cases and if the only
difference between may actually just be the final View that is rendered
(html, xml, json)?

Senchas interpretation of GPL is bordering on the "ridiculous":
http://www.sencha.com/legal/open-source-faq/
Example
For example: let’s take a mortgage processing software program. Let’s say
that the application has a front-end (that generates web pages linked to Ext
JS JavaScript) that communicates over
JSON/HTTP with a backend service. This backend service contains approval and
validation logic for this application alone. Even if only the front-end uses
Ext JS code, you should consider that the combination of front and back ends
constitutes the application, and the source code for both back and front end
would need to be provided to the application’s end users under GPLv3 if the
application is used by an end-user who is not part of the same legal entity
that holds the GPLv3 license to the Ext JS code.
Sorry but.... THATS a BUNCH of BULL! So now GPL infects across "http
messaging protocol" as well? Simply referencing a GPL javascript file via
URL constitutes your application being a derivative work and having to be
GPL'd as well? The problem with the above logic is that the Serverside
Application is "upstream", Ext JS is talking to "it" not the other way
around, the server side application is not dependent on Ext JS, the
"Browser" is the one thats dependent on ExtJS to render the view, so what
then... all Browsers need to be GPL'd as well? I would buy that the
javascript you write thats dependent on the ExtJS javascript would need to
be GPL... but not the server delivering the REST interface it communicates
with. The direction of dependency is important here...
We will need to have a dialog about Javascript framework choices that are
fitting for DSpace's BSD style licensing and determine if we tolerate using
a library from a company with such an odd interpretation.
