[Clas12_software] JLab appointment

[Johann Goetz]

Hi Dennis and Mauri,
I just talked with Latifa and I will shortly be an official JLab employee
(50% of the time). The main project she wants me to focus on is the
consolidation of the geometry information of CLAS12 and the associated
interface (API). The first step is to determine what is out there. I will
survey what parameters are being used for each subsystem -- probably by
contacting the individuals in charge of design and/or construction. We'll
see if I can collect enough information to make a report this coming Tuesday
during the software meeting. At any rate, I have added this as part of the
upcoming  agenda.

I envision using the mysql database design from GlueX (Mark Ito and Dave
Lawrence) for versioning and storage of the geometry parameters. I can then
produce an API in C++ or Java (or Python?) which we can wrap in whatever
language people want. The final step would be to expose the API as a CLARA
service.

That being said, could anyone from the clas12_software group comment on the
aspects of geometry they are familiar with? I.e., who to talk to in order to
get an understanding of where parameters are stored and/or associated
algorithms for converting these to actual positions in the hall. Otherwise,
I'll probably start by going through the TDR.

Thank you,
--
