2010-03-19: Demystifying the GEOSS Infrastructure - Virtual Workshop 2

Standards Implementation Virtual Workshops

GEOSS can be thought of like a pool where resources can be shared. The resources are provided using standards. By sharing the resources using standard methods to the pool, multiple applications can be built on top of the pool that access a variety of data.

AQ Infrastructure Slides

What is the Pool?

• Components - Community Catalog, GEOSS Service and Component Registry, GEOSS Clearinghouse
• Community Catalog is a Web Accessible Folder: http://capita.wustl.edu/dataSpaceMetadata_ISO/
• Community Catalog is registered in the GEOSS Component and Service Registry:
  • as a component: http://geossregistries.info/geosspub/component_details_ns.jsp?compId=urn:uuid:089197b9-3abd-42fb-afe2-c431cdd2204f
  • the associated catalog service: http://geossregistries.info/geosspub/service_details_ns.jsp?serviceId=urn:uuid:fa0874bf-3797-447f-aeea-c3644a7e0527
• GEOSS Clearinghouse searches for Catalog services in the GEOSS Registry
• GEOSS Clearinghouse provides search across all component and service descriptions that are in the Component and Service Registry.
  • For the WAF, GEOSS Clearinghouse harvests the metadata records from the Community Catalog once a day

Everything that is registered in the GEOSS Registry or in a community catalog can be found in the clearinghouse.
