2. CFEOD Background
Developed by US Group on Earth Observations (USGEO) Data Management Working Group
Issued by OSTP/NSTC/CENRS on 2016 March 23:
rk_for_earth_observation_data.pdf
Goal: improve interoperability among federally held Earth observation data
Recommendations to agencies, not binding requirements
Feedback/concerns can be submitted through agency USGEO DMWG rep

4. structure
The aspects of data management in the document are organized as follows:
Data Search and Discovery Services
Data Access Services
Data Documentation
Compatible Formats and Vocabularies
In each category, recommendations are discussed at three levels
Standards and protocols
Methods and practices
Implementations

5. Data search and discovery services
Provides guidance on the creation and organization of searchable catalogs of data
Machine-to-machine interfaces should be supported
The National Strategy for Civil Earth Observations called for establishment of formal standards-based catalog services which could be indexed by commercial search engines
Some examples of standards and protocols
Schema.org
OGC Catalog Service for the Web (CSW)
OpenSearch
Digital Object Identifiers (DOIs)

6. Data access services
Standards-based services facilitate interoperability by making it easier to obtain and combine data form multiple sources
Some examples of standards and protocols
OGC Web Map Service (WMS)
OGC Web Map Tile Service (WMTS)
Data Access Protocol (DAP)
OGC Web Coverage Service (WCS)
OGC Sensor Observation Service (SOS)
OGC Web Feature Service (WFS)

7. Data documentation
Documentation, in the form of structured metadata, makes it easier for users outside of a particular group or community to discover, access, use, and understand.
