Here is a very preliminary version.

\def\defineVERSION
   {\dosingleargument\dodefineVERSION}

\def\dodefineVERSION[#1]%
   {\dododefineVERSION#1}

\def\dododefineVERSION$#1: #2$%
   {\setvalue{VERSION:#1}{#2}}

\def\getVERSION#1{\getvalue{VERSION:#1}}


\defineVERSION[$Revision: 1.4$]

\defineVERSION
 	[$File: something$]

\starttext
This file, \getVERSION{File}, is at version \getVERSION{Revision}
\stoptext


I changed the interface to make it more ConTeXtish. AFAIU version 
control, this should work with RCS, CVS, and subversion. It is not too 
hard to extend this to $Data:$ and $Id:$.
