[kepler-dev] ptII version number?

[David Welker]

Hi Christopher,

The reasoning behind this is as follows.

We don't really want people to think of Kepler as means of obtaining  
Ptolemy. Switching to Ptolemy from Kepler will be disabled in the   
Module Manager. If someone wants Ptolemy, they should get it from you  
guys directly, using your distribution mechanism, which varies  
significantly from our distribution mechanism and uses an entirely  
different technology (i.e 'make' instead of 'ant') and an entirely  
different "module" system. Furthermore, this is based on a branch of  
Ptolemy in the Kepler repository, not a release of Ptolemy. It is  
necessary to make such a branch because for this prototype, every  
module that is published must have a corresponding branch to enable  
patches.

Of course, as a prototype, the exact techniques that we use will be a  
matter for further discussion before any final decisions are made for  
the Kepler project.

I think it would be more confusing, not less, to indicate the actual  
version of Ptolemy that this was released from. Kepler modules version  
numbers for publishing purposes should be distinguished from Ptolemy  
releases, which are entirely different things. Of course, we could  
publish information on the wiki about the very rough correspondence  
between these two things in the documentation, for those who are  
curious. But Kepler does not do releases of Ptolemy. Instead, Kepler  
uses Ptolemy releases. Also, we are developing consistent naming and  
other conventions for modules and your suggested names do not fit into  
those conventions.

I look forward to discussing this with you further after November 11  
when your schedule clears up a little bit and you have time to discuss  
Kepler issues.
