Oh, well. I have a model with lots of requirements. Some of them were called "mandatory" requirements, but we have made up our minds, and now they are called "basic" requirements.
So I have to update the model in order to reflect this change. Changes to be made:
1) Names of some packages (change Mandatory / mandatory to Basic / basic)
2) Names of some diagrams (idem)
3) Content of some notes (idem)
4) Content of some elements' descriptions (idem)
5) Names of some requirements (change of MA01, MA02... to BA01, BA02, ...)
I suppose this should be easy for someone knowing SQL or the like, but I don't know a single word of it. Can anybody offer me a hint, other than the brute-force approach of using an hex editor on the .eap file

?
