[ZODB-Dev] ZODB4 project plan

[Eron Lloyd]

=46rom a Web developer's perspective, the reason I never really employ ve=
rsions=20
when making changes to a site is because you're tied to the ZMI to edit t=
he=20
necessary objects. I know there is no simple (or feasible!) way of making=
=20
versioned objects available through a VFS (using FTP or WebDAV), so it's=20
usefulness comes to a grinding halt. *However*...if we could somehow=20
exploit(?) the locking/versioning functionality of WebDAV in the ZMI (wit=
hout=20
requiring an extensive third-party WebDAV client), that would suffice. Do=
es=20
this sound like it has some potential?

Giving it some thought, now, it would've been great to say, have a versio=
n=20
object at the site root: /NewSiteVersion, and be able to access this obje=
ct=20
through FTP/WebDAV as website.com/NewSiteVersion/<VirtualRootToRestOfSite=
>=20
where all the versioned objects could be safely edited using third-party=20
tools.

My .02,

Eron
