The following points were presented and discussed (see File:AQ SOLTA 2011-Data Catalog side meeting.pdf)
Catalog architectures
* Centralized catalog * Distributed catalog * Broker catalog
GI-cat: a broker catalog to federate heterogeneous standard services
* Catalog services (CSW, OpenSearch, ...) * Inventory services (THREDDS, WAF, ...)
- Access services (WCS, WMS, ...)
Demo: GI-go, GI-portal - what are the facets of description for AQ data?
Broker catalog use cases
* Addition of new heterogeneous server nodes to the existing capability
- Addition of new interfaces to the available services
Added MACC WCS
Discovery standards
* Metadata standards (ISO 19115/ISO 19139) * ISO19139 publishing mechanisms (FileSystem, Web Accessible Folder-WAF, Native XML Database-NXD, CSW/ISO) * CSW queryables review (ISO properties for discovery)
Access
* OGC services (WCS, WMS, WFS, SOS) * Metadata conventions (CI_OnlineResource) for OWS data access * Brokered-access (EuroGEOSS access broker)
Interoperability
* The Air Quality Community Catalog (metadata and service interfaces, functionalities and role) * Test outcomes of GI-cat federating the Air Quality catalog * uFind functionalities and features
uFind: faceted-search; facets extracted from capabilities (key-value-pairs encoded in keywords with <facet>:<value> syntax); there exist an AQ controlled vocabulary (derived from CF conventions)
Issues
* Metadata for discovery in AQ * AQ data granularity level * How can the AQ Community Catalog and GI-cat complement each other effectively?
