Programmatically query of workstatus information in SAC

Dears,

I need to access to the actual workstatus informations from the program (Javascript). Is it possible?

Is there any object/library/etc which might help to obtain these info? Otherwise, are these in a sort of blackbox in which we do not have any possibility to interact, if not through the UI?

Thanks in advance for your help.

Regards,

Andrea
