Recommendation on Discovery Elements Mapping for Metadata

Summary

“It is recommended to GIGAS to prepare guidelines for mapping community metadata into the core queryables and propose according change request to OGC”

Classification

Category	Catalogue and Metadata
Identifier	REC-CAT-002
Type of recommended activity	Further Investigation about the subject
Organisations addressed	GIGAS in collaboration with INSPIRE, GEOSS, GMES technical teams

Additional information

Context	Each initiative has defined its own discovery metadata elements. This mapping would help identify precisely the commonalities and discrepancies between the discovery metadata profiles. It is the first step towards interoperability, as it would allow client applications and catalogue services implementing transformations based on these mappings to transparently access discovery metadata from the different initiatives in a fixed, standardized way. Harmonization of these discovery metadata elements is the next step.
Rationale
Dependencies	REC-CAT-001 Cross-initiative scenario

Main discussion points	None
Roadmap	GIGAS consortium to prepare a cross walk of the INSPIRE, GEOSS and GMES common metadata elements identify issues of semantic mismatch, cardinality issues, etc. and resolve questions raised in the 3 communities prepare guidelines for mapping community metadata into the core queryables prepare Change Request to CSW 3.0 for the addition of new queryables to the baseline
