Coordinated Assessments April 3, 2014 Workshop Data Exchange Standard: Overview, Changes, Additions, and Direction Mike Banach PSMFC
What is a “Data Exchange Standard (DES)”? It's about DATA It's about EXCHANGING (transferring) those data It's the STANDARD for transferring those data Also known as: o Data Exchange Format o Data Exchange Template o Data Dictionary
Very specific, English language descriptions of: Data categories The table(s) that will hold the data o Purpose and name of each table o Purpose and name of each column in each table o Codes used in each column o Rules for required columns, acceptable values, etc. o Relationships among tables and among columns What is a “Data Exchange Standard (DES)”?
How is DES used? Used by database managers o When creating databases for storing data o When working with newly-arrived data Used by programmers when writing programs for moving data Not specific to one technology o But is the guide to implementing them
Who developed the DES? BPA CBFWA (r.i.p.) Colville Tribes CRITFC IDFG Nez Perce Tribe NMFS ODFW PSMFC USFWS USGS WA Governor's Salmon Recovery Office WDFW Yakama Nation
How and when is the document updated? Modifications to existing tables on as- needed basis Additions as possible. (But not too fast) Plan is to revisit document annually, but try to live with existing versions whenever possible
Current data categories Exist in the 2012/2013 DES versions All are for natural origin fish All are highly derived “indicators” at the population scale for a single year o Spawner abundance o Smolt to adult ratio o Recruits per spawner Recruits can be any life stage Spawners can be all fish, adults, or ♀♀
What is changed in the 2014 version? “ID” column Run names changed to match NMFS Allows multiple estimates for same population X year o Among agencies o Within an agency New column indicates which is TRT estimate
What is changed in the 2014 version? NOSA table: % natural replaced with % hatchery o Done to match the new PNI table House cleaning Improved definitions Renamed a column or two
What is new in the 2014 version? Characterizing hatchery programs o All for population scale and single year Total fish spawned (plus #hatch & #natural) Egg take PNI Egg to release survival SAR Recruits per spawner
General layout of tables Every table is a “flat” 2-D table Should not be beyond those who normally use spreadsheets No programming required
General layout of tables Each table has sections for: o Defining unique records o Values of “indicators” o Values of “metrics” o Age composition (when appropriate) o Methods documentation o Comments o “Supporting information”
General layout of tables Defining unique records o “ID” o Population and year o Agency and method
General layout of tables Values of “indicators” o Point estimates o Confidence limits Values of “metrics” o Point estimates o Confidence limits Age composition (each age class) o Point estimates o Confidence limits
General layout of tables Methods documentation o ‘Protocols’ and ‘methods’ from MonitoringMethods.org Supporting information o Contact person o Date record was updated o Data status (draft; reviewed; final)
For today Questions? We wish to get full group’s approval to adopt current draft DES as new version, effective today Get ideas / directions for the next indicators to pursue (see next slide)
Additional indicators suggested so far “Juvenile abundance” is next in line o This is assumed to be number of outmigrants; clarification during DES development Hatchery fish stray rate Hatchery fish catch/escapement profile Expand scope to include “resident fishes” A couple others I misplaced (please remind me)
