Monday 16:00-18:00 Data Catalog Side Meeting (everyone welcome)
The following points were presented and discussed (see the 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?
GI-cat - ESSI Federated Catalog
AQComCat - Air Quality Community Catalog (Kari)
GI-cat-AQComCat link - Federating AQComCat into GI-cat; Accessing GI-cat from AQComCat

Tue 16.00-18.00: Scope and Type of Data to be Served
Data Providers: Existing data Data Hubs - how do they work?
Data Classes
- by data source-driver (mandated, research)
- by content/platform (emission, ambient, remsens, model)
- by space-time (global, regional)
Data Level
- Primary (original), Secondary, Mediated
- Raw , processed , how?
Tue 18.00-19.00: General Discussion, with wine and cheese
Wed 8.00-10.00: Breakout reports, general server items
What few things must be the same, so that everything else can be different?
Report from the IT breakout session: Community server software
Report from non IT breakout session: ADN scope, providers, users
Report from the pre-workshop Data Catalog side meeting
Crossover topics between IT and non-IT issues
Wed 10.30-12.30: Data network catalog and clients
Functionality of an Air Quality Data Network Catalog
Catalog content and structure (granularity) of ADNC?
Minimal metadata for discovery, data provenance, quality, access constrains?
Single AQ Catalog? Distributed? Service-oriented?, Access rights
Catalog Clients expand here
Wed 16.00-18.00: Relationship, cooperation, governance
3 call-in presentations, (10 mins each max!)
- 16:00 US EPA - Terry Keating (HTAP, CyAir..) ...perspective on AQ data networking;
- 16:10 Nat.Park Serv. - Bret Schichtel (VIEWS) on data collection & usage in VIEWS DSS -
- 16:20 GEO - UIC. Adam Carpenter on GEO Earth Observation Priorities
16:30-17:00 Discussion
17:00 - 18:00 User perspective, value chain.
Relationships, cross-thematic links (EGIDA, ESIP), How can we collaborate? Network governance
Wed 18.00-19.00: General Discussion, with wine and cheese
Thu 8.00-10.00: Networking impediments and opportunities
JJ Bogardi, Global Water System Project (GWSP) at EGIDA, Bonn:
Nature of Networking Projects: Complex funding; mixture of paid and voluntary; multiple obligations; international; differing project maturity; governance, cultures
Which glue keeps it together? Trust and personal affinity. Common objectives and scientific values. Mutual respect. Mutual benefit (win-win). Complementarity. Donor dictate
Lethal“ ingredients. Turf mentality. Budget discrepancies. Too much competition. Lack of data and information exchange. Donor jealousy
- Clear statements about obstacles: no clear structure; no dedicated funding and no clear idea(s) yet how to do it.
- Opportunities, fixes: ID manageable work packages; Find, organize, distribute reusable components, resources; Create win-win situation
Thu 10.30-12.30: ADN user relations/help, whom, what?
- Target User communities
- Use cases for different applications... from scientists to managers, media people and the general public)?
- How can users find out about (each) system? Big future issues: data quality, traceability, metadata..
Thu 16.00-18.00: Workshop outputs, outcomes, plans?
What are the anticipated outputs? Agreement on community WCS server for grid and point data; server governance, distributed catalog; workshop summary
What are the anticipated outcomes? More servers and data added to the shared data pool and more willing users of shared data.
