Hi startx,

indeed, that's an important step in each production and I agree with you
that we should try to offer some solution here.

Do you know "Celtx" ?

In the past, it's gotten some reputation. Basically they provide
an integrated pre/production environment.

I'm not sure if the software itself is open source (they just label it
as "free"). Anyway, they're providing an central service to use their
server for managing productions (Uhm... personally I wouldn't do that)
And of course, they offer to sell you extensions....

Yes, basically this is still kind-of in the scope of our project, but
what happens there largely depends on contributions. In the core, we'll
build a system of "Assets", which allow us to attach the metadata we
need to work with those entries within the main program. Assets are
organised into folders, and the GUI will at the bare minimum show a
human understandable presentation of this structure.

For going beyond that, there are two possibilities:
- - extending by plugins
- - write a "sister application" which shares the session format with Lumiera

For the latter approach, we had a "DesignProposal" some time ago:

While the core team in its current shape needs to concentrate on the
main application, we'd encourage everyone to expand on those ideas.
