[Hps-analysis] datacat example

[McCormick, Jeremy I.]

Hi,

I'm close to starting the Auger jobs that will populate the JLAB datacat with the EVIO files from the Engineering Run.

Here is an example...

http://hpsweb.jlab.org/datacat/display/datasets/HPS/data/raw/hps_005688.evio.0

The built-in metadata fields are:

file format - always set to 'EVIO'

data type - always set to 'RAW'

size - file size on disk

master site - always set to 'JLAB'

master resource - path of EVIO file on MSS

run min/max - set to the file's run number

events - count of physics events (does not include control or EPICS events)

The per file custom metadata fields I have added thusfar are the following:

BAD_EVENTS  - number of bad (unparseable) events

BLINDED - flag if file is blinded

END - flag if END event exists

EPICS_EVENTS - number of EPICS events

FILE - file sequence number

FIRST_PHYSICS_EVENT - first physics event ID

FIRST_TIMESTAMP - first timestamp

GO - flag if GO event is present

LAST_PHYSICS_EVENT - last physics event number

LAST_TIMESTAMP - last event timestamp

LED_COSMIC - number of cosmic triggers

PAIRS0	- number of PAIRS0 triggers

PAIRS1 - number of PAIRS1 triggers

PRESTART - flag if PRESTART event exists

PULSER	0 - number of pulser triggers

SCALER_BANKS - number of scaler banks found

SINGLE0 - number of SINGLE0 triggers

SINGLE1 - number of SINGLE1 triggers

Please tell me if there is any other metadata that should be included here.  I would prefer not to go back and assign additional metadata later unless it becomes absolutely necessary.  (It would have to be done in a separate step or the files would need to be deleted/re-added.)

Also, if you want any of these metadata field names modified for clarity of meaning, let me know.

Thanks.
