Hi Thomas, I need a mechanism that generates different renditions on adding subnodes (e.g. a file) to a certain node (e.g. folder type). Typical scenarios may be rendering of thumbnails or producing a PDF rendition say out of a CAD file. Such a mechanism is found in most DMS systems, i.e. such a rule is given once to a certain folder, and then always executed until it gets explicitly removed (likely many server restarts later). Important notice: this happens "real time" on the fly, as opposed to the journaling feature in JCR 2.0 pointed to by Jukka. So, looking forward to 3.0 ;) -- Juerg
