Hi Christophe,
I have "some" experience both with Podcast Producer (don't get me started on
the way Apple announced the end of the Xserve) and Matterhorn, so my
perspective on this topic should _hopefully_ be productive.
If I'd were to be tasked with the migration out of Podcast Producer I would
separate it on 2 different puzzles to solve:
-Migration of the existing content
-Replacement of the PcP engine (capture,post production,publishing) and its
linked dedicated hardware and yes I'm pointing at you mac minis in the
classrooms for the capture, and Xserve/Xgrid/Xsan clusters in the data-centers
for processing and storage.
The emphasis being in the difference between migration vs replacement.
The good news ("migration" == "bad news" in my book) is that Matterhorn can be
the Free and Open Source application that helps you for both content migration
and as a replacement for the lecture/capture automation engine, all this
without any need to have a JAVA developer onboard.
You can just pick which Matterhorn module you need which in some extent was
also possible with PcP workflows, Matterhorn though pushes that modularity (aka
Service Oriented Architecture) way beyond what Podcast Producer did. The
hardware being more a question of budget (is it more cost effective to replace
everything Apple with $BRAND hardware and FOSS or try a migration at the
application layer since after all Os X is based on Unix).
The reason why I'm pointing at the modular approach is because of the way it
works in Matterhorn and how it can help you without any specific JAVA language
skill set i.e. REST APIs.
So to summarize I doubt the community will spontaneously write a generic
"silver bullet type" PcP to Matterhorn migration module to be bundled with a
release any time soon, and the reason is that tapping into the REST APIs via
the language of your choice allows the transfer of any content to Matterhorn
internal "library".
There is however as a non-Java person myself one feature I leveraged
extensively in PcP I'm hoping to see coming to Matterhorn, that is a workflow
operation that allows the execution of an external script and to which you can
pass variables from within the Matterhorn environment (pcastaction shell
anyone?).
Also I wish Apple would open source the Quartz Composer as this was quite a
nice piece of software for advanced post production automation albeit quite a
complex one.
Last but not the least because of my involvement with PcP and Matterhorn I know
for a fact that there are actually several Universities all around the world
with the same problem to solve; so maybe one of them will end up writing such
PcP to Matterhorn migration middleware and open source it, point is thanks to
the REST APIs you don't have to wait for that.
