How the ReqIF IDs are generated [message #1796808]

Hello,

I'm trying to find out how identifiers like "_f3jAgMpOEeiqhq5afgXBhA" in <SPEC-OBJECT IDENTIFIER="_f3jAgMpOEeiqhq5afgXBhA" in ProR are generated, but from searching in the source code I could not find this information. Could you please help me on this ?

Thanks!

Setting UUIDs is a feature of EMF. Check out this generated file:

org.eclipse.rmf.reqif10.serialization.ReqIF10ResourceImpl

Thank you for your help.

Unfortunately I could not find how the UUIDs as in <REQ-IF-HEADER IDENTIFIER="_iD0y4c4UEeilM_Q6XUt6MQ"> are generated. I can only find the setID(String identifier) functions, but not a place where this method is called with a generated UUID that begins with a "_".
In /org.eclipse.rmf/org.eclipse.rmf.reqif10.common.Reqif10Editor, I could find that UUIDs of the form <REQ-IF-HEADER IDENTIFIER="rmf-40535036-7ed8-4170-ab8d-f273beb8a233"> with a "rmf-" at the beginning are generated using a function in java.util.UUID.

But where in the source code and how are the UUIDs beginning with "_" generated ?

And what is the difference between UUIDs beginning with "_" (e.g. "_iD0y4c4UEeilM_Q6XUt6MQ") and UUIDs with "rmf-" (e.g. "rmf-40535036-7ed8-4170-ab8d-f273beb8a233") ?

Nowhere, or more precise, by the Eclipse Modeling Framework (EMF). If you want to find the code, you need to inspect the EMF code.

This is simply a scenario where we decided not to use EMF for UUID-generation. That's why it's done explicitly. The rmf- prefix has simply been added for verbosity in the XML.

I found the UUID generation with the "_" in the beginning in this class in EMF.

Thanks a lot for your help and best wishes from Essen.
