Documentation Cluster - September Telecon [1]
Submitted by Krbm on Thu, 2012-09-06 16:131) Air Quality metadata - Erin
2) approaches to doing crosswalks - Ted
3) other dialects - who has one they want to talk about?
1) Air Quality (AQ) Community Documentation: Publishing and Using ISO 19115 Metadata (by Erin, Ted, and Rudy Husar)
· AQ has variety of data (ex. Emission, satellite, population, models) and are producing secondary products
· Formed the AQ Data Network
· Use WCS (NetCDF – CF)
· http://bit.ly/QjApLF [7] - spread sheet of AQ metadata needs
· See metadata as a spiral
1. Collect all existing documentation
2. ID community/project specific metadata needs
3. With expert help – examine standards and guidelines
4. Validate with schema and schematrons
5. Publish
6. Iterate –as data evolves
· Request for Documentation Cluster
· Expand the NOAA GEO-IDE wiki (https://geo-ide.noaa.gov/wiki/index.php?title=Main_Page [8])
· Code list definitions
· Examples of metadata – specifically Hierarchical metadata with sensors on platforms, etc.
· (Ted) the difficult part is bring communities together
· GEO MS – reads likes CF but not CF it was/is a NASA standard
· Greg – It is project specific
· (Ted) The issue is still what is lost in translation
· (Greg) At Dublin meeting, happy that group was able to agree on one or two standards
· (Steve) worked in various fields (ecology/enviro sustain/archaeology)
· Groups usually lay out a few requirements & then think they have done enough to code
· Thing being done in complete ignorance of other research
· Think ESIP is the place to work on this
· (Greg) in Dublin – repeated the same exercise of defining fields that were needed
· Some people needed it – it was a way to wrap mind around the problem
· (Ann) – there is no standard that crosses all the standards – most are not aware of what is needed to cross disciplines
2) Ted – Crosswalk
· Described the crosswalk and its element (see previous notes for description of spirals and dialects)
· Looking for more standard way for the data - ?ontology
· But has new and better ways to transform the data
· Html – table
· Wiki - http://wiki.esipfed.org/index.php/Documenting_People [9]
· Discussed data.gov
· Brought up ISO code lists on the NOAA EDM wiki
Discussed how there are different terms because some groups thought they didn’t overlap
3) Open discussion
· (Kelly) – NISO metadata talk – discussed grouping metadata into simple, simple-moderate, and complex based on the number and types of terms – thinks it could help with scales of transformation
(Ted) simply = discovery… working with same time of system
· (Ted) Add Quantifying the change between standards to next meeting agenda
· (Alek) will send terms to CF list – group oked
· Next meeting set for Oct 17 at noon EST
1) Aleksandar will send terms to CF list
Erin Robinson, Kelly Monteleone, Aleksandar Jelenak, Steven Aulenbach, Ted Habermann, Ann Keane, and Greg Frost
