Thanks Geert. I cannot have my source database maintain the versions. Also I don't want to maintain the versions for all the documents (just specific documents only).
I need to tell my source database if I need to maintain the version or not in my target database for specific document. In the mean time I am going the through dls.

In fact, the dls library should facilitate thiswithout needing you to code much yourself. On the other hand, if the database is accessed through webdav, you will need triggers or CPF to make sure previous copies are preserved (in same or other database). To answer your question: you can add triggers to your source database. There are different trigger events for new inserts, updates and deletes, as well as for database startup. You will need xdmp:eval, xdmp:spawn or xdmp:invoke with external variables (to pass the document) and explicit database setting to be able to access a documents database other than the one connected to the current app server. More details on triggers, dls, and eval can be found here: http://developer.marklogic.com/pubs/4.1/apidocs/Triggers.html http://developer.marklogic.com/pubs/4.1/apidocs/dls.html http://developer.marklogic.com/pubs/4.1/apidocs/Ext-6.html You might already have found it, but chapter 17 of the dev-guide explains the concepts of Triggers, and also provides some examples: http://developer.marklogic.com/pubs/4.1/books/dev_guide.pdf Kind regards, Geert > drs.
