How to ask for compliance?

“ … Purchaser seeks geospatial products that provide maximum interoperability with purchaser’s and data sharing partner’s systems. To accomplish this, purchaser seeks to make maximum use of open standards provided by the Open Geospatial Consortium (OGC), ISO …”

Metadata Validation

used in

CINERGI

(Community Inventory of EarthCube Resources for

Geosciences Interoperability)

32

Goals

• Large inventory of high quality information resources across disciplines, with traceable provenance, usable across EarthCube research scenarios

• Engaging geoscience community in creating and curating the inventory

• Enabling search and integration across domains, and facilitating navigation across information objects of different types (resources, people, software, etc..)

3 Levels Community Inventories Validation

1 – Schema2 – Rules not enforced by schema3 – Community rules

http://cite-dev-03.opengeospatial.org/teamengine/

Level 1 - Schema

Level 2 – Rules not enforceable via Schema

Level 3 – Community Rules
