Monday Evening: Registration and Social
Tue 8.00-10.00: Self-Introduction, 5 mins/participant
In order to make efficient use of our time in Croatia, we ask you all to prepare for the workshop in the following ways (aside from arranging your travel etc.):
- Slides 1-2: Name, Institution, Relevant research, development or organizational work on AQ data system interoperability and networking
- Slide(s) 3-(4): Involvement and participation in projects, programs, i.e. list of Integrating Initiatives. Potential contributions.
Tue 10.30-12.30: Introduction of Hubs, AQ CoP, 5 min each
This session will be a status report from major data hubs
- DataFed
- FJ Juelich
- NGC/CIERA
- EBAS
- DLR/ACP
- EEA NRT
- AIRNow
- AQMEII
--Afternoon 16:00 US Nodes: VIEWS, AeroCom, RSIG, GIOVANNI --
Existing Data Hubs
- Hubs are established organizations to deliver AQ data
- Part of their mandate is to integrate, harmonize data
- The data offerings are directed toward clients
- Provide data through conventional data transfer
--- Current - Network comparison--- Data integration is pursued for:
- Facilitating access and reuse through a single access point
- Providing more comprehensive information by combining complementing data.
Data hubs already perform data integration within their respective domains. AQ data networking extends the scope of the integration by connecting
- Integrating the integrating hubs (non-intrusively!)
- Use standard interfacing protocol for lose coupling i. e. networking
- Generic processing services that are applicable to all data
Data Catalogs
- AQ Community Catalog
- GI-cat
Networking "what few things must be the same
- Hubs expose a fraction of their holdings as standards-based data access web services services
- Data resources are
- Role of GEO AQ CoP
- Role of Integrating Initiatives
Tue 16.00-18.00: IT: AQ Community server software
This sessions is standards and conventions | Implementation for gridded and station data | Development tools | Server performance
Issues re. the use of netCDF and other data formats
Data server performance issues/solutions
Data Servers: Technical Realization (IT) Issues and Solutions
Gridded data service through WCS
Delivery of station-point data
Access rights
Server co-development tools, methods
Relationship to non-AComServ (non-NetCDF) WCS servers
Real Data-to-WCS-Mapping tructure
Tue 16.00-18.00: NoIT: ADN scope, providers, users
- VIEWS
- GIOVANNI
- RSIG
- AEROCom
Wed 8.00-10.00: Breakout reports, general server items
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
Possible discussion topics/focus on cross-overs between IT and non-IT issues
- standard definitions (clarity, ambiguity, completeness, ...)
- standard development and documentation
- open-source server software development
- platform issues, portability
- coding language(s), code interchangeability
- coding style and software development approaches
- Data Content
- organisation of data
- data formats, standard compliance
- data access
- performance
- flexibility
- user friendliness
- meeting user demands (fitness for purpose)
- governance, responsibilities, etc.
- Open Source collaborative approach. Issues?
- General software design: Multi-layer, Multi-protocol. Standard-Convention driven
- Porting, Installation. Issues?
- Maintenance, governance. Issues?
- Criteria for single (trusted ?) 'primary' data source
- Designations for secondary, derived, augmented data sources
Wed 10.30-12.30: AQ network: Servers, Catalog, Clients
What few things must be the same, so that everything else can be different?
Metadata for finding and understanding, CF, ISO)
Data access/use constrains, quality control, data versioning, etc.
What is the design philosophy
Service oriented (everything is a service), Component and network design for change; open source (everything?!)
Network-level data flow, usage statistics (GoogleAnalytics), performance
... goal is to obtain a good basis for discussion in the following breakout sessions, both from the IT and non-IT sides.
- Server Software Design (uFIND). Issues?
Functionality of an Air Quality Data Network Catalog (ADNC)?
Content and structure (granularity) of ADNC?
Interoperability of ADNC
- Interoperability with whom? what standards are needed? CF Naming extensions?
- AQ Discovery Metadata Convention (for use in ISO, Data Catalogs...)
- Extend CF Naming conventions for Point Data
- Devise human-readable CF naming equivalents?
Access rights and access management
What are the generic (ISO, GEOSS, INSPIRE) and the AQ-specific discovery metadata?
Minimal metadata for data provenance, quality, access constrains?
Single AQ Catalog? Distributed? Service-oriented?
- GI-cat
- uFind
Wed 16.00-18.00: Relationship, cooperation, governance
- User perspective, value chain .. user can not find..
- EPA - HTAP Terry Keating??
- EEA - H. Anderson??, Peder ??
Relationships, cross-thematic links (EGIDA, ESIP) How can we collaborate?
Thu 8.00-10.00: Networking impediments, opportunities
- Clear statements about obstacles..
- no organizational structure,
- no dedicated funding or
- no clear idea yet how to do it (or several independent ideas?).
- Opportunities, fixes
- Identification of manageable work packages
- Reusable components, resources
JJ Bogardi, Global Water System Project (GWSP) at EGIDA, Bonn:
Nature of Networking Projects: Complex funding .., multiple obligations. Interdisciplinary and international. Differing project maturity. Mixture of paid and voluntary contributors. Governance and project cultures may differ.
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
What can we do to achieve a "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..
Relationship to non-AComServ WCS servers
- Issue: protocol compatibility, standard compliance, data format(s)
- Issue: is there a need? How can we benefit from "other" data? How can they benefit from AQ data?
- Issue: which protocols? (OpenDAP?, GIS servers?)
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? Better understanding of the network, higher level of trust and concrete steps toward turning the ADN from virtual to real
What are the short-term opportunities? Do we have
Common long-term goals and visions?
