Solta 2011 Agenda

< Back to | Workshops | Air Quality Data Network

Monday 16:00-18:00 Data Catalog Side Meeting (everyone welcome)

Location: LeoMar, Boldrini/Bigagli

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

Location: LeoMar, Vik/Fialkowski

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?

Wed 8.00-10.00: Breakout reports, general server items

Location: LeoMar, Domenico/Gaussev

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

Location: LeoMar, Bigagli/Eckhardt

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 18.00-19.00: General Discussion, with wine and cheese

Group dinner

Thu 8.00-10.00: Networking impediments and opportunities

Location: LeoMar, Kjeld/Ludewig

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?

Location: LeoMar, Galmarini/Dye

• 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?

Location: LeoMar, 'Schultz/Husar

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.

Thu 18.00-19.00: General Discussion, with wine and cheese

Friday: Boat trip
