This WP9 Activity Report described the activities performed in September 2012 by Beneficiary and Task.

It is part of the Monthly Activity Report.

T9.1 Data Access and Storage Facilities

FAO Activities

FAO has overseen the integration builds of the tree-based access components submitted for release in 2.10.0, fixing a number of issues emerged in release builds as fragile-testing problems. FAO has prepared a presentation for the upcoming TCOM on the integration of tree-based access components within the rest of the system, liaising with CNR and NKUA to prepare a plan and propose solutions to the issues associated with each integration point (DTS, result presentation, annotations, home library, collection explorer). FAO has supported CNR in the development of the tree-manager plugin for the species-products-discovery service.

CNR Activities

The CNR activity focused on introducing the ability to execute jobs in Species Discovery Service to create:

  • Darwin Core Archives by taxonomy ids;
  • Darwin Core Archives retrieving children by taxonomy ids;
  • CSV files;
  • specific CSV files for Open Modeler.

The service is now able to show the status and progress of the job.


  • Bugs fixed
  • Ability to execute jobs in Species Discovery Service

T9.2 Data Transfer Facilities

CERN Activities

A new version of the data transfer components have been released for gCube 2.10.0. In addition an implementation of a Data Transfer Portlet has started. Upgrade and plans for the Data Transfer part have been presented at the TCom


A new version of the data transfer components has been released for gCube 2.10.0

NKUA Activities

NKUA has been working on performance test in combination with the usage along with ResultSetConsumer of Application Support Layer Search. The results will be presented at the 3rd TCOM. In addition, several bug fixes have been done in the gRS2.



Terradue Activities

In this period we worked, as expected, on the WPSClient. A first stable version is available and ready to be delivered. This is based on the 52 North WPSClient libraries, and it offers a Java library and a Command Line interface. Next period will include the pending documentation. The library provides the link between the EnvironmentExplorer Library and the WPS-hadoop and thus should be integrated in it.

T9.3 Data Assessment, Harmonization and Certification Facilities

CNR Activities

SDMX registry: Study of SDMX 2.0 and 2.1 specifications: framework, information model, registry specifications, implementors and web service guidelines for registry and datasource.

Development of a simple prototype registry with REST interface capabilities that manages SDMX 2.1 documents only, storing data with gCube storage service (mongoDB).

The Tabular Data Widget has been updated:

  • Added support to MySQL SQL dialect
  • Added support to column sorting
  • Added support to multiple instance of TDW in same application

No deviations or corrective actions to report.

  • Better understand of SDMX technologies
  • First prototype of a REST SDMX registry
  • Improvement of TDW with new supported Database and features
