Hi Andreas,

thats good thinking. So are you proposing to add them at the driver
level and do not expose it or don't implement it at all? Of course
databases implement sophisticated mechanisms but escpecially MySQL
doesn't (AFAIK).

> An implementation of the CmsVfsDriver for JCR for example likely would not have access to checksums and it might not make sense to add them in the form of additional nodes or properties (maybe data integrity mechanisms are in place at a lower level). Also some databases implement sophisticated data integrity mechanisms already.
