Hi,

I've simplified the proposed metadata for EVIO files in the datacat.

Here's a sample from hps_005688.evio.0 in form "key = value"

  runMin = 5688
  runMax = 5688
  eventCount = 261446
  FILE = 0
  BLINDED = false
  FIRST_HEAD_TIMESTAMP = 1431653987
  LAST_HEAD_TIMESTAMP = 1431654003
  FIRST_PHYSICS_EVENT = 1
  LAST_PHYSICS_EVENT = 261442
  FIRST_TI_TIME = 68176224756
  LAST_TI_TIME = 83808331904
  TI_TIME_DELTA = 999865516
  TI_TIME_OFFSET = 1431653918606600024
  BAD_EVENTS = 0
  TRIGGER_RATE = 16.3404
  LED_COSMIC = 0
  PAIRS0 = 4811
  PAIRS1 = 231307
  PULSER = 1402
  SINGLES0 = 5893
  SINGLES1 = 18204

The main change here from last example which I sent around is that I stripped out some of the event counting fields (EPICS events, etc.), and I have added code for getting TI time data information.

The first and last TI time and the offset match up with Sho's data for this file, so it seems correct.

Are there any additional fields that should be added here?  Are the field names clear?  Do any of these values seem like they should *not* be included?

I'm planning to crawl the Eng Run 2015 EVIO file data soon (starting tomorrow?), so if something should be changed/added let me know ASAP.
