Data Discovery/schema.org (Doug, DanBri)

History & context of schema.org 

Approach based on 

• web-pages (dataset landing pages) with embedded JSON
• sitemap for deep sites

Principles and practices are the infrastructure

Spatial metadata (SteveR, SimonC)

Geographic identifiers and reference systems - place-names, coordinates, topological relations

Range of expertise and understanding ranging from geography professionals through to users

Supported in various 

• specialised geographic metadata schemas (ISO, schema.org, STAC, FGDC, ...)
• general-purpose metadata schemas (DCAT v2)

Potential work groups

1. Data for an SDG indicator e.g. Infant mortality, social exclusion
2. DRR - risk/hazard maps - 
   
   1. data quality - provenance requirements  (see 8.) 
   2. potential for developing a common risk/hazard ontology; applied to different use-case using design patterns? (also see 4.)
3. Systematizing & sustaining data collections over a network of data providers
4. recommendations/practices for building and maintaining vocabularies and ontologies - start with DRR vocab + hazards ontology
5. practices (library?) for data harmonisation & cleaning - ranges, units
6. recommendations/practices for bridging between vocabularies & ontologies (combine with 4.)
7. Variables/observable properties (important for data discovery) (survey and manifesto?) - DDI variable cascade + EnvSci I-ADOPT + schema.org VariableMeasured 
8. Data quality/provenance challenges - write recommendations
9. Transparency in data → information → knowledge → action chain  (related to provenance 8.?)
