Incremental version history, or how to version only those node elements that have changed

Why it is worth using the incremental version history (reducing the size of the database, clear information for the user about the elements that have changed) How to implement modification history (source data, schema, samples)

When you use document versions in Alfresco all versions are stored with complete set of attributes and content even if nothing changed. In some cases it may increase size of database and storage by duplicated data. In this lecture I’m going to show how to reduce duplicated data in document versions and create simple document history containing only document change log.

Lecture is based on real project experience and I will show working solution available in github.
