oops, this was intended for the exist-db guys...but the question are similar...anyone used BaseX with a checkout-checkin scenario?
First of all: I'm also interested to hear more about this from our users..
Talking about locking functions, we plan to generalize our WebDAV locking feature to a general database locking mechanism. The WebDAV locks already contain information on the user who created the lock, a timeout, the scope (shared vs. exclusive), the lock id, etc., and this info could be extended by the lock time and other (maybe even application specific) info. Do you have some examples for data that could be specific to an application?
In our SGML CMS you were able to checkout parts of a bigger document for example a chapter. In this case we needed additional information inside the checked-out document - perhaps not on the lock itself - we used processing instructions for that as far as I recall.
Being able to store arbitrary key-value pairs on a lock would be sufficient. Otherweise I would store such application specific data as an additional XML file containing these informations.
