Capturing Metadata from Vault DVS file

[maaser]

Dear All - I'd like to capture meta data for all of the messages in our enterprise vault implementation - we'd like to run some basic analytics on historic communications.  We are currently using version 10 of vault.  I'm interested to capture the following meta data - Time stamp, from email addres, to email address, and subject line.  Would love any thoughts or guidance on how we may be able to capture this data.

Time stamp is easy, that is in the SQL database.  To/From and subject line will be next to impossible with doing searches in DA or Clearwell and that will be a massive undertaking.

How much data do you have in EV?  Is it mailbox archives and journal?

I am curious what your use case is here.
