Subject codes to help export to Invenio/CDS

[jbenito]

• Organizers should be able to select from a list of subjects for their events (one or more)
• This subjects would be exported with HTTP AP, RSS (and others?)
• Subjects should be able to be added from Admin page

Subjects:

in Inspire we use the subject codes

Astrophysics
Accelerators
Computing
Experiment-HEP
Gravitation and Cosmology
Instrumentation
Lattice
Math and Math Physics
Theory-Nucl
Other
Phenomenology-HEP
General Physics
Theory-HEP
Experiment-Nucl

But I think it would be more appropriate to use the more comprehensive set used in CDS (or a subset of it):

Particle Physics - Experimental Results Particle Physics - Phenomenology Particle Physics - Theory Particle Physics - Lattice Nuclear Physics - Experimental Results Nuclear Physics - Theory  General Relativity and Cosmology General Theoretical Physics Detectors and Experimental Techniques  Accelerators and Storage Rings Engineering in General Health Physics and Radiation Effects Computing and Computers  Mathematical Physics and Mathematics Astrophysics and Astronomy Nonlinear Systems Condensed Matter Other Fields of Physics Chemical Physics and Chemistry Engineering Information Transfer and Management  Physics in General Commerce, Economics, Social Science Biography, Geography, History Other Subjects Science in General Popular Science
