Keep in mind that tools are meant to support processes, not the other way around.  \pror{} is a flexible tool, and it can be tailored to support your processes.  But development processes are explicitly outside the scope of this handbook.

There are a few derivatives of the RMF project that may be confusing.  The following will
help you to understand the ecosystem and how the pieces fit together:

\begin{description}
-\item[RMF.] The Requirements Modeling Framework (RMF) is an open source project that is managed by the Eclipse Foundation.  It consists of software code, documentation, mailing lists, online forum, etc.
-\item[ProR.] ProR is the name of the user interface that allows users to work with ReqIF-based requirements.  ProR is typically installed into existing Eclipse installations.  There used to be a standalone build of ProR, which has been discontinued.
-\item[RMF Core.] While ProR is the frontend of RMF, the Core is the back end.  This distinction is primarily intended for developers.
-\item[ProR Essentials.] The company Formal Mind created this collection of add-ons that make ProR much more usable.  For instance, Essentials allows for the editing and rendering of formatted text.
-\item[formalmind Studio.] As there is no standalone version of ProR available, Formal Mind created one, which comes with Essentials preinstalled.  For users who just want to edit requirements'', this is the most convenient way of getting started.
+\item[RMF.] The Requirements Modeling Framework (RMF) is an open source project that is managed by the Eclipse Foundation.  It consists of software code, documentation, mailing lists, online forum, etc. It is a software framework, and you need an application to use it. Like:
+\item[ReqIF Studio.] This is an application that is based on RMF and maintained by the company Formal Mind.  For users who just want to edit requirements'', this is the most convenient way of getting started. ReqIF Studio contains some useful extensions to RMF, which are called:
+\item[Essentials.] The company Formal Mind created this collection of add-ons that make RMF much more usable.  For instance, Essentials allows for the editing and rendering of formatted text.
+\item[ProR.] ProR is the old name of the user interface that allows users to work with ReqIF-based requirements.  You can build ProR from the RMF sources, but there is no ready-to-use download of ProR.

\section{Compatibility}

-\pror{} and RMF require at least Java 6 and Eclipse 3.8.  Some features of ProR Essentials require Java 7 from Oracle (not openJDK).
+\pror{} and RMF require at least Java 6 and Eclipse 3.8.  Some features of ProR Essentials require Java 7 from Oracle (not openJDK). Of course, you can use newer versions of Java without problems.

-formalmind Studio is based on Eclipse Luna (4.4).

+ReqIF Studio is based on Eclipse Luna (4.4). This has not been upgraded, as some large organizations still use fairly old versions of Java. Using a newer version of Eclipse would require a newer version of Java as well.
