This WP10 Activity Report described the activities performed in April 2013 by Beneficiary and Task.

It is part of April 2013 Monthly Activity Report.

T10.1 Data Retrieval Facilities

NKUA Activities

The activities of NKUA included:

  • In the context of full integration of Forward Index with Couchbase (#897):
    • The implementation has finished and only testing and integration with the portlet is remaining.
  • In the context of data fusion implementation (#1184):
    • Most of the work has been completed.
    • The next step is to import the new operator in the SearchSystem and testing.
  • Authoring the documentation of the new FullText Index. The related wiki pages are Admin Page and Developer's Guide.
  • In the context of removing the Content Manager dependencies:
    • Storage Handling has been refactor to use the Storage Manager (#1560)


None


The following components have been released in gCube 2.14.0 :

  • storagehandling.2-2-0
  • storagehandling-stubs.2-2-0
  • fulltextindexnode.1-0-1
  • fulltextindexnode-stubs.1-0-1
  • elasticsearch-gcube.1-0-1

FORTH Activities

None


None

T10.2 Data Manipulation Facilities

NKUA Activities

During last month, gCube Data Transformation Service has been upgraded in order to support forward index rowsets creation out of Tree Manager Collections (#1574). Currently, trees produced by OAI and SPD Tree Manager plugins are supported.

Also, both personalization services (UserProfileAccess and ProfileAdministration) have been refactored to store and retrieve the user profiles in the storage system. To accomplish this they interact with the sms-client library instead of CM, that is going to be dismissed. (Related tickets are: #1543 and #1544)

T10.3 Data Mining and Visualisation Facilities

CNR Activities

During the month of April CNR conducted activities in several directions about Data Mining. On one side, the Trendylyzer facility was approached, which aims at finding biodiversity indicators from the Obis data #1653. On the Statistical Manager side, activity regarded both the Service and the underlying libraries.

The Service was enhanced in its design, in order to account for the management of external data sources #1319.

On the libraries side, activities focused on the comparison between OGC maps #1432 and consequently on the retrieval of information from OGC maps #1617. Furthermore, facilities to perform Digital Signal Processing were integrated #1045.

On the visualization side, CNR explored and indexed the geographical layers "hidden" into the NetCDF files downloadable from the MyOcean and the World Ocean Atlas repositories #1614. The layers were eventually published in production environment under the standard ISO 19139 format.


No deviations to report.


  • Integration of Digital Signal Processing facilities in the statistical libraries
  • Publication of environmental layers from MyOceans and World Ocean Atlas under standard ISO 19139 format.

NKUA Activities

A new component "InteractiveLayers" has been released to extend the GeoExplorer visualisation abilities. It provides time filtering for the available layers on the GeoExplorer. Additional information is available in the ticket 1549 and in the wikipage Data_Visualisation_Plugins


Development of the QuantitativePropertiesVisualisation is discontinued. Its functionality is planned to be provided by the InteractiveLayers component.


  • Released a new component "InteractiveLayers" in 2.14.0 release.
  • A Wiki page has been created to support further development of the component.

Terradue Activities

  • We Developed main use-cases of the OWS Context OGC standard in iMarine:

- GIS Viewer to save the view as an OWS Context document - GIS Viewer to load a saved OWS Context document - WPS processes to generate OWS Context documents complementing the main output of the process - allow the discovery of a catalogued OWS Context documents

T10.4 Semantic Data Analysis Facilities

FORTH Activities

During this month FORTH worked on performing the necessary updates for releasing XSearch components and on investigating alternative designs for XSearch components for improving scalability (#1006).


none


The following components has been released in gCube 2.14.0

  • xsearch-portlet: 1.0.2
  • xsearch-service: 1.0.3

Furthermore a successful application of the XSearch technology on the domain of patent search is described in the following paper which acknowledges the support of iMarine.

  • P. Fafalios, M. Salampasis and Y. Tzitzikas, Exploratory Patent Search with Faceted Search and Configurable Entity Mining. In procs of the 1st International Workshop on Integrating IR technologies for Professional Search in conjunction with the 35th European Conference on Information Retrieval (ECIR’13), Moscow, Russia.

FAO Activities

Activities include:

  • Review potential of adding semantic services to Cotrix, e.g. to feed FLOD
  • Review potenatial workflows in FAo-FIPS for code lists and reference data


The beneficiary should report here major issues faced in the reporting period and the identified corrective actions, if any.


Internal discussion Documents:
