Documentation Cluster - September Telecon
1) 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 - 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)
· 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
· 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
