I'm sure you are "missing something" and that properties and "assocs" can be versioned in a version2Store, the "creator" and "modified" fields are very special cases so that's not where versioned properties are stored.

However you will need to wait a little more patiently untill someone who knows the low level details reads your posting and decides to answer.

All aspects & properties are versioned, by effectively replicating the live node to a version node (plus a few decorated properties). Since the version node is now stored natively, the new store implementation is significantly smaller (and faster) than previously. It also means that it could be optionally indexed and queried in a more meaningful way. As Mark mentions, the auditable properties are a special case.

ps. If you have a specific test case that causes a repeatable regression then please contact support and/or log in JIRA

Hi Jan,
yub, I read the Wiki page before, but I don't get it. Perhaps help me with a little sample.
For example how can i read the cm:description property of an versioned node. I tried to find this value via nodebrowser, but I don't find it.
You mentioned properties and aspects, what about assoc?
Thanks for your reply,
Jan

Hi,
ok, I tried with Alfresco Explorer & properties like description & title are versioned as expected. Using Share (Alfresco 3.0.1 Ent) it isn't (Aspect title isn't part of the versionNode)…So it seems to be an issue with Share/Webscripts used by Share. I also recognized that properties set in your Working Copy in Share are also lost when checkin, e.g. description is empty an not copied from Working Copy or previous version…
So, its hopefully fixed in coming 3.1 Ent, otherwise I'll raise an issue.
I now get, that a versionNode is "simply" a copy of the orginal node, copied to version2Store + same special properties like frozenXXX.
Thanks for your efforts…
Jan
