This WP10 Activity Report described the activities performed in November 2012 by Beneficiary and Task.

It is part of Monthly Activity Report.

T10.1 Data Retrieval Facilities

NKUA Activities

The activities of NKUA included (i) the design of the integration of the Fulltext Index with ElasticSearch according to the ticket #896 (ii) minor bug fixing in Resource Registry and Index.

Bug fixes according to the following tickets:

  • Resource Registry related : #502, #503
  • Index related : #501


None


The following components have been released in gCube 2.11.1::

  • IndexCommonLibrary 3-3-4
  • ResourceRegistry 1-3-2
  • ResourceRegistry_NODEPS 1-3-2
  • RRModel 1-3-1
  • RRPlugins 1-0-1

FORTH Activities

During M13 FORTH started investigating some issues regarding data retrieval facilities. In particular FORTH started an evaluation of the snippets mechanism provided by gCube Search (discussion in ticket #838) and the quality of ranking the results GCube search (discussion in ticket #684).

Terradue Activities

The beneficiary should report here a summary of the activities performed in the reporting period


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


The beneficiary should report here a bullet list highlighting the main achievements of the reporting period

T10.2 Data Manipulation Facilities

NKUA Activities

An implementation of a client library for Data Transformation Service (#841) has been completed, based on client-library framework. More specifically, Data Transformation Service API is exposed to the client, while hiding probably frustrating complexity from the client side.

Implementation of the following library has been completed:

  • dts-gcore-client-lib

T10.3 Data Mining and Visualisation Facilities

CNR Activities

CNR has redesigned the Statistical Manager to deal with more complex inputs and outputs. Furthermore, some algorithms for general purpose modelling have been introduced. In particular Feed Forward Neural Networks have been implemented to perform simulation of real valued functions. Algebraic operations, introduced in previous months, have been bug fixed and setup for distributed computations. A refactoring of the Statistical Manager service has been designed in order to manage multiple outputs and complex inputs (e.g.files). At current stage, in fact, the SM manages only one output per algorithm. In the Ecological Engine Library some design operations have been performed in order to figure out how to manage the time dimension.


No deviations to report.


  • Refactoring of the SM service and library for complex inputs and outputs management
  • Implementation and deploy of Feed Forward Neural Networks for simulating real valued functions
  • Design of distributed computations for Occurrence points analysis

Terradue Activities

Terradue has integrated IRD R application taking a GML file with fisheries data to produce a graphic. The application has been integrated as a legacy application on the WPS-hadoop framework using the streaming approach. This geospatial process will be thoroughly described on the wiki page: https://gcube.wiki.gcube-system.org/gcube/index.php/Geospatial_Data_Processing This activity has stimulated the comments on FAO's geospatial visualization document to include R as complementary approach to manage raw and aggregated data in iMarine.

IRD R simple application as a WPS process.

T10.4 Semantic Data Analysis Facilities

FORTH Activities

During M13 FORTH further worked on some minor improvements on the xsearch-service component. Furthermore FORTH started investigating some issues regarding the ability to search over multiple collections. In particular it has been observed that when multiple collections are selected (through the portal) then search is not available, or it is only available for the common fields of the selected collections. A related ticket for monitoring the discussions has been opened (#839). In parallel FORTH is planning to develop a web application (as a proof-of-concept) that will use gCube search over ASL-HTTP API of a production portal. This new web application requires only a little effort to be completed. A related ticket has been created to discuss the specific details of this task (#840)
