Versioning entire "folders" with many files might not be efficient.

Yes, everything is copied in Jackrabbit. There is no optimization in the version storage format (eg. using diffs), because unlike in revision control systems, it is quite likely that versions get deleted, so they are kept independent. Also it is optimized for trees with fine-granular content (eg. a page in a CMS), not for arbitrary sized subfolders with lots of binary content. > In my understanding of what written in JCR specs there is actually no way of > stopping the versioning at one (or any specific number) level of depth, and > even if I set a rule in the child nodes, so to ignore any further level, the > VERSION rule is applied to whole root subtree. Have you used OnParentVersion (OPV) with a value of IGNORE? See 3.13.9 ff of the JCR 2.0 spec for more: http://www.day.com/specs/jcr/2.0/3_Repository_Model.html#VersionableState Or this tutorial: http://jtoee.com/jsr-170/the_jcr_primer/5/ CND docs: http://jackrabbit.apache.org/node-type-notation.html Regards, Alex -- Alexander Klimetschek alexander.klimetsc...@day.com
