Usage-based Data Discovery - 1st meeting
From Federation of Earth Science Information Partners
- Chris Lynnes (EOSDIS) - Lead
- Bob Downs (SEDAC): Intrigued by user perspective, looking to broaden discovery to include the exploration needed before deciding on datasets
- Carson Davis (NASA/IMPACT): Working on Knowledge Graph, corpus of 90K research articles related to Earth Observations
- Doug Newman (Data Use Architect for EOSDIS EED-2 contract): working with Chris Lynnes on EOSDIS knowledge graph
- Ed Armstrong (PO.DAAC): long term interest in discovery. Worked on AIST MUDRODS project, which included a discovery component
- Joe Lee (The HDF Group): works on HDF use website
- Jonathan Blythe (BOEM): works on Environmental Studies. Creating a KnowledgeBase, wants to see that go beyond individual systems
- Karen Moe (Disasters Cluster): works with people who are not data experts, looking for easier way to find the data they need
- Mark Parsons (RDA): has worked on data citations for a long time. Researchers also want to know who is using their data
- Megan Carter (ESIP Community Director): provide ESIP help. N.B.: Call for summer sessions coming soon!
- Siri Jodha Singh Khalsa (NSIDC, RDA, GEO): Chair of RDA Data Discovery Interest Group, also working on Geo Knowledge Hub (the inspiration for the EOSDIS Knowledge Graph!)
- Tyler Stevens IEOSDIS): worked on GCMD, now on CMR
- Dave Neufeld (NOAA)
- It's important to record why/how we know about a given relationship, not just because someone says so. (Esp. pertinent for the more general entities like Sustainable Development Goals). Must be able to do objective analysis on the graph.
- The W3C Provenance model may be helpful here. Also, nano-publication.
- How to handle subsets, e.g., spatio-temporal subsets?
- Should consider whether tool relationships are within scope.
- Precipitation datasets seem like a good starting point.
- Lynnes - write up some text for Megan's newsletter
- Lynnes - set up regular meeting with ESIP G2M, some time other than 4th Thursday
- TBD - spin off a subgroup to work on use cases
- Lynnes/Newman - generate a sample export of EOSDIS knowledge graph
- Blythe - provide info on use of W3C Prov model
