Presenter: G. Coro (CNR)

Slides: .pptx file

Participants: A. Antoniadis (NKUA), W. Appeltans (UNESCO), N. Bailly (FIN), C. Baldassarre (FAO), J. Barde (IRD), C. Bekiari (FORTH), E. Blondel (FAO), F. Brito (Terradue), L. Candela (CNR), V. Canhos (CRIA), H. Caumont (Terradue), P. Cauquil (IRD), G. Coro (CNR), A. Ellenbroek (FAO), P. Fabriani (E-IIS), N. Holdsworth (ICES), G. Kakaletris (NKUA), A. Manzi (CERN), Y. Marketakis (FORTH), P. Pagano (CNR), M. Taconet (FAO), E. Travaglino (E-IIS);

A concrete list of data sources that the community is willing to have available in the infrastructure should be defined.

  • (F. Brito) an alternative approach might be to focus on the variables (e.g. SST, Salinity) to be made available, then to prioritize variables and finally to identify the potential providers/data sources;
    • Identify variables (SST, PAR, Ice concentration) => prioritisation
    • Identify datasources (repositories) => prioritisation
    • Identify tools (including data policies) => prioritisation
      • (N. Holdsworth) Issue on global variables or local variables? Variable prioritisation is driven by data coverage (temporal and spatial) and quality.
  • (J. Barde) yet another approach should be to build to build a catalogue of products and services by relying on OGC standards, e.g. register a CSW URI; E.g. SeaDataNet is a catalogue of CSW services;
    • (P. Pagano) this might have limitations on effective data exploitation that is limited to the protocols supported;
    • catalogue is effective for resources discovery;
  • (M Taconet) The Board should start identifying the needed resources and define the scope;
  • (J. Barde) Data providers are requested to describe their data and products by ISO19115 and ISO19119 metadata formats (this is part of INSPIRE);
    • (J. Barde) they are working with a company developing code to transform NetCDF files to ISO standards;
    • it is expected that the infrastructure links data sources compliant with such formats;
    • clients are willing to use / are expecting to use these approaches;
  • (V. Canhos) the sustainability of the infrastructure depends from the sustainability of the resources providers;

The GeoSpatial cluster goals/objectives are

1. Data discovery - main repositories of environmental, fisheries and biodiversity geospatial sources netCDF-CF repositories: My Ocean, Seadatanet, IRD World Ocean Database, Ocean data portal Other iMarine partners geospatial sources (defined by OBIS, IRD, FAO, ICES)

2. Data access - main taxonomic and biodiversity repositories Increased granularity in data access with OPeNDAP, WCS, WFS (including GML2-3) Defining geospatial needs (including product subscription approach) and their availability

3. Data processing; R geospatial, WPS/HADOOP, IE potential in enrichment, geospatial analyses and modelling Define enrichment needs of bio-ecological or activity occurrences with environmental data: OBIS Ocean Physics, VTI, VME Designing and planning implementation for enrichment capacity Advanced geospatial analytical and modelling features - e.g. R geospatial, reallocation, aggregation Defining advanced geospatial processes required in reallocation, aggregation, interpolation Designing and planning implementation for geospatial processes capacity

4. Data visualization - Interactive map viewer enabling visualization of geospatial biodiversity and fisheries data Defining Visualization functionalities - SPREAD, OBIS, VME-DB, VTI Designing and planning implementation for visualization

Closing remarks

i-Marine would become a catalogue of geospatial sources? i-Marine is planning to offer processing capacities for environmental enrichment and a subscription. i-Marine is identifying business cases derived from the points above.

IE provides the services and data to allow the reallocation of catch statistics within i-Marine

IRD the long term vision is to deal with OGC standards to allow third party providers and users to enjoy data and services within i-Marine.

HC: we address the same challenges as other infrastructure in Europe. The key is how the infrastructure address downstream services. Then how the I/F addresses scientists. For that, scientists need to see what data is available (e.g. environmental data, time-series) in terms of quality, time/spatial coverage, etc. i-marine could provide a dashboard to show that.

Sustainability is a key point, seen by some as a constraint. CRIA shows that the sustainability depends on the sustainability of the federated sources and providers.

Participants: A. Antoniadis (NKUA), W. Appeltans (UNESCO), N. Bailly (FIN), C. Baldassarre (FAO), J. Barde (IRD), C. Bekiari (FORTH), E. Blondel (FAO), F. Brito (Terradue), L. Candela (CNR), V. Canhos (CRIA), H. Caumont (Terradue), P. Cauquil (IRD), G. Coro (CNR), M. Doerr (FORTH), A. Ellenbroek (FAO), P. Fabriani (E-IIS), S. Garavelli (TRUST-IT), N. Holdsworth (ICES), J. Keizer (FAO), G. Kakaletris (NKUA), A. Manzi (CERN), Y. Marketakis (FORTH), P. Pagano (CNR), M. Taconet (FAO), E. Travaglino (E-IIS);

FLOD OpenSearch facility integration should be further discussed.

C. Baldassarre: One of his expectations is to outsource the management of the facilities developed to the infrastructure;

  • this aspect should be discussed; A concrete plan and a deep knowledge of the technology is a prerequisite for this;

The TLO is a fundamental approach for a number of use cases;

(J. Keizer) Which are the RDF data sets (publicly) available:

  • pictures, publications, maps, etc.
  • AgInfra is willing to show data linking between the two projects;
    • A further discussion is needed;

C. Baldassarre: we might have as a goal to expose a SPARQL for the whole infrastructure;

gCube OAI-ORE Implementation

Presenter: R. Tsantoulli (NKUA)

Slides: .ppt file

Participants: A. Antoniadis (NKUA), M. Assante (CNR), L. Candela (CNR), G. Coro (CNR), A. Ellenbroek (FAO), G. Farantatos (NKUA), A. Manzi (CNR), V. Marioli (CNR), F. Sinibaldi (CNR), F. Simeoni (FAO), R. Tsantouli (NKUA), E. Travaglino (E-IIS);

The configuration of the OAI-ORE entity should be carefully discussed. E.g.

  • it currently exposes the whole content;
  • the URI of the repositories are part of the configuration;

Another aspect worth to discuss should be how to generalise the proposed approach to something more than gDoc only.

The scope of the solution should be described. In particular, an integration with the Tree Manager should be carefully discussed. This fits with WP11.

The notion of scope is integrated in the URI of objects.

In general, the security aspect and the offering of WP11 has to be carefully analysed.

WP11: status and plans

Presenter: R. Tsantoulli (NKUA)

Slides: .ppt file

Participants: A. Antoniadis (NKUA), M. Assante (CNR), L. Candela (CNR), G. Coro (CNR), A. Ellenbroek (FAO), G. Farantatos (NKUA), A. Manzi (CNR), V. Marioli (CNR), F. Sinibaldi (CNR), F. Simeoni (FAO), R. Tsantouli (NKUA), E. Travaglino (E-IIS);

A lot of contributions are missing. NKUA might follow a more aggressive approach, e.g. list the expected contributions and ask explicitly to members for contributions.

WP6 Portal session

Presenter: M. Assante (CNR)

Slides: .pptx file

Participants: A. Antoniadis (NKUA), M. Assante (CNR), L. Candela (CNR), G. Coro (CNR), A. Ellenbroek (FAO), G. Farantatos (NKUA), A. Manzi (CNR), V. Marioli (CNR), F. Sinibaldi (CNR), F. Simeoni (FAO), R. Tsantouli (NKUA), E. Travaglino (E-IIS);

The Software Upload Wizard should not be conceived to serve admin users only, e.g. in the case of war upload a different role should be supported.

There are some similarities with account facilities. Further discussion is needed to identify possible integrations.

Circles/groups are not in place, neither planned. Among the privacy levels the single VRE a user is subscribed should be supported.

SPREAD

Presenter: E. Blondel (FAO)

Slides: .pptx file

Participants: A. Antoniadis (NKUA), M. Assante (CNR), E. Blondel (FAO), L. Candela (CNR), G. Coro (CNR), A. Ellenbroek (FAO), G. Farantatos (NKUA), A. Manzi (CNR), V. Marioli (CNR), F. Oehler (Eurostat), P. Pagano (CNR), F. Sinibaldi (CNR), F. Simeoni (FAO), R. Tsantouli (NKUA), E. Travaglino (E-IIS);

In the proposed process/workflow there are important points to be discussed, e.g.:

  • where to search for intersection objects between source and target layer?
    • intersection objects are expected to be produced by Emmanuel and they will be stored in FAO GeoServer (all of them are in a single layer);
    • the discovery is implemented via a Java Library;
  • how to search for source and target layers?
    • they corresponds to the intersection objects existing & stored in the above layer;
    • the source layer should be "FAO Major Area" in the case of FAO data;

Tasks:

  • Emmanuel will circulate some sample data (JSON) for testing purposes;
  • FAO/T2 will review the data reallocation algorithm and test it;
  • CNR will integrate the WPS client to invoke the algorithm once it has been tested;
