Let me first admit to not being a webtrees expert, although I am going
to use it. Webtrees is a 'fork' in open source terms from the popular
PhpGedView. It initially populates the custom database from data in one
or more GEDCOM files which remain in the file store but aren't referred
to again in operation after the initial loading use. The idea is that
the database is updated online by those collaborating in the project
and, subject to configuration; any user can export a GEDCOM for their
own use at any time.
Multi-media is more problematic when it comes to portability, the GEDCOM
FILE statement contains just a file pointer to a multimedia item, not
the item itself. It's unlikely that this location would stay the same
through a migration to webtrees so the program optionally strips off the
leading part of the path and replaces it with a media directory
constant. It's the left to the user to migrate media items manually.

Interesting. I d/l-ed the source. At webtrees/setup.php, line 575 they
start creating the db tables.
My /impression/ is that they store a GEDCOM file, and from that extract
a few things:
Also, they allow uploading of 'media', presumably sound and video.
But is that sufficient?
I assume not, since it implies to me they only store info which can be
imported from a GEDCOM file (or perhaps added online, but which would
nevertheless always be GEDCOM compatible).
If I've misunderstood, please correct me.
