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

It is part of April 2012 Monthly Activity Report.

T10.1 Data Retrieval Facilities

NKUA Activities

NKUA has worked in three directions during this period:

  • Managing the following incidents in the reporting period, which led to fixes released in gCube 2.8.1:
    • ticket #404, regarding missing configuration files on the Full Text Index Lookup Service.
    • ticket #402, regarding missing ehcache configuration files on Search System.
    • ticket #403, related to the way Resource Registry handles scopes during updates.
  • Finalizing the development which was initiated during the previous period and performing tests for the Resource Registry enhancements. The new version of all components was successfully tested in the development infrastructure.
  • Authoring deliverable D10.1: gCube Query Language Specification.
    • The document describes the role of the query language used by the gCube Search System, its association to standard CQL, the implemented extensions to CQL and the association of gCube Data Sources with the query language.
    • Authoring and editing of the deliverable are complete. The deliverable entered the reviewing phase at the end of this period.


  • Delivery of D10.1 is delayed. Effort was put to complete editing before the end of the reporting period, in order to minimize actual delay from the final phases of the workflow.


  • Release of org.gcube.search.searchsystem.3-0-1 in gCube 2.8.1, fixing #402
  • Release of org.gcube.index-management.common-library.3-3-1, fixing #404
  • Release of org.gcube.execution.RRGCubeBridge.1-2-2, fixing #403
  • Completion of development and testing of Resource Registry enhancements.

T10.2 Data Manipulation Facilities

NKUA Activities

NKUA focused on extensively testing the new Workflow Adaptor for the Data Transformation Service. Main directions were the integrity, performance and advance to fully functionality of the transformation process.

During this period, main test cases composed real demands driven from production environment and were investigated and actually executed. Also, system was tested on high demand of transformation requests, numerous input and complex transformation steps towards desired content type.

Moreover, experiments included heterogeneous Data Sources in order to homogenize them to single content type. Data Transformation Service performed well under these tests. System resources used and execution time of each experiment was proportional to its complexity. DTS performance compared to the previous monolithic system is tolerable for simple transformation tasks, but more scalable to the intensive ones.

Furthermore, Milestone MS42, describing the specifications of Data Manipulation Facilities has been achieved.

Upcoming moves, will be focused on fault tolerance of the transformation process and fault recovery, and also on concurrent execution of the same transformation processes on different execution nodes.

T10.3 Data Mining and Visualisation Facilities

CNR Activities

CNR continued in exploring possibilities to exploit D4Science as a computational infrastructure in the context of the Statistical Manager service. Several experiments were performed in order to run the Aquamaps algorithm on Pe2ng. Other experiments are being performed on the Executor software. Deep details can be found on the trac systems in terms of performance charts and timing evaluation: #263


  • Even the Executor usage is being explored in order to have a baseline system. The calculated Pe2ng performances could be not sufficient to the scopes of this WP task.


  • Interaction with Pe2ng was achieved and correctly managed
  • Performance Analysis of Pe2ng was produced
  • Interaction with Executor was started

T10.4 Semantic Data Analysis Facilities

FORTH Activities

In the context of Semantic Data Analysis, milestone MS45 has been produced. In particular two dedicated wiki pages were created. One for specifying the Semantic Data Analysis and can be found here and one for specifying the applications that will be used, namely X-Search, and can be found at X-Search link.

Furthermore we prepared the final version of the paper “Web Searching with Entity Mining at Query Time” which got accepted and will be presented at 5th Informational Retrieval Facility Conference (IRF’2012), which describes the prototype of X-Search over FAO FIGIS and FLOD.
