I would like record to this BTree index only Resources commited to ZODB database. How can I connect a function to commit event ? In this function, how can I found all object modified ? How can I found all object removed to the database ? Other question : are there already a package to perform this task ?

Other question : are there already a package to perform this task ? The matching package is zope.catalog. It provides all you need (catalog and indexes) to handle your task. Objects creations and modifications are followed automatically by several subscribers as soon as this package is correctly registered. z3c.catalog and hurry.query packages can be good extensions packages to look at... In repoze.catalog documentation, I read : Note that when you call index_doc, you pass in a docid as the first argument, and the object you want to index as the second argument. When we index the peach object above we index it with the docid 1. Each docid must be unique within a catalog; when you query a repoze.catalog catalog, you’ll get back a sequence of document ids that match the query you supplied, which you’ll presumably need to map back to the content object in order to make sense of the response; you’re responsible for keeping track of which objects map to which document id yourself.
