The air quality community metadata has evolved into a set of key-value pairs and links to WMS/WCS data access services.

Metadata Issues

  • Need convention for metadata distributor (catalog) contact/DataSpace link
  • Define thesauri/controlled tagging - How do others cite GCMD vocab in ISO 19115
  • (Convention) How to link dataset with data access service - Include serviceIdentification object or use distribution or both?
  • distinguish between metadata and data distributor

Community AQ Metadata Records

Community AQ metadata records were developed in order to find data through the GEOSS Clearinghouse. They were built by first determining the minimum set of fields needed for GEOSS registry. Then the community decided to use the ISO 19115 metadata for geospatial information standard. The ISO 19115 standard required that the Community AQ profile include the core set of fields for ISO. Then the AQ record was extended in order to add additional fields that are needed by AQ users in order to find the data through faceted search interface, AQ uFIND.
