>what does an 'extra service' mean?
>Are you talking about a client/server architecture? yes. In short, you can consider it as the Channel Archiver extension/upgrade with (one of) a new driver to the hdf5 backend. As a result, conceptually everything (including file structure) would be the same except several extensions like support of the EPICS 4 structured data types. The type registry and associated topics will be presented at the next EPICS meeting. -Nikolay From: Emmanuel Mayssat [[email protected]]

Are you talking about a client/server architecture? An add-on piece of software you have to pay for? Is there a web page (a pointer) that talks about those topics and their implementation? (sample code?) It turns out a good starting point may be http://www.hdfgroup.org/hdf5-quest.html#GENERAL Although you may not have the answer yet, has anyone though (at least conceptually) of a h5 tree structure (database) design for archiving? Would that be time based? (tree node like /date/20120315) Would that be hardware based? (/chassis_id/device_type/device_id) Would that be PV name base? (archiving of AAA:BBB:CCC pv is located at /AAA/BBB/CCC ) Would that be subsystem based? ( /injector/solenoids/I:SO01/current ) the last 3 at once with links? Thanks, -- E |
