The ProR and ReqIF Studio look like mostly dead projects to me. They
didn't manage to build a reasonable user base and community in the last
couple of years. I experienced stability problems with both tools (e.g.
NULL pointer exceptions). The documentation is not really great and if
you start to try things beyond simple examples it gets hairy. I don't
want to work with such tools and waste my time.

My experience and one of our trainees with Papyrus are not really great.
This is a complex tool you have to use intensively in your day to day
work to be productive. There are some videos available, but getting
started is quite difficult. I guess most people learn it with the help
of colleagues. I also guess that it is used via in-house versions and
not all known bugs are fixed in the public version. It is overkill just
to manage requirements with it.

First, we need a data model for the requirements in the scope of RTEMS.
You need this model also for ReqIF. ReqIF is the Requirements
Interchange Format, the emphasis is on interchange. It is an open
question, if it is suitable as a project internal representation for our
requirements. At the moment I tend to use some sort of XML file and use
a simple text editor.
