Allow schema changes
--------------------
Key: NXP-424
URL: http://jira.nuxeo.org/browse/NXP-424
Project: Nuxeo Enterprise Platform 5
Issue Type: New Feature
Security Level: External (All people)
Components: JCRConnector
Reporter: Florent Guillaume
Assigned To: Bogdan Stefanescu
Priority: Critical
The platform must allow ways of changing schemas during the development of a
project without having to delete all the storage or break all existing
documents.
Use cases:
1. change a field from String to Date (for instance),
2. remove a field,
3. remove a schema,
4. (the use case of adding a field or schema is treated by the simpler NXP-237)
Note that any solution will have to take into account migration inside the
version storage, which is mostly immutable in JCR implementations.
