EuroVO-AIDA, Work Package 7: Data Access Protocols and Data Models

Joint Research Activity

Contact person: (ESA, Pedro Osuna)

Objectives

Taking into account requirements from the scientific users and the data centres, participate in the IVOA Working Groups for the definition of the IVOA standards and protocols for data access, data description (taking into account in particular data provenance and data quality), and query language, beyond the present initial versions (“simple” protocols). Input will be given to the Data Access Layer, Data Models and VO Query Language IVOA Working Groups.

Description of work

Perform R&D studies for Data Access, Data Model and VObs Query Language protocols and standards in the context of the IVOA working groups. WP7 is lead by ESA with contributions from the other WP7 participants, in particular of CNRS for the data modelling aspects. In particular that includes:

  • Studying the DAL, DM, VOQL standards. Assessing possible technologies to implement these standards
  • Participation to the IVOA WGs discussions, mail forum, teleconferences
  • Participation to writing the standards specifications document of these DAL, DM, VOQL
  • Participation to the IVOA Technical forum to present the findings and implementations of these DAL, DM, VOQL standards
  • Writing prototype implementation these DAL, DM, VOQL standards onto real data holdings from European Data Centres
  • If applicable, publish these implementations into the Euro-VO Registry of VObs resources
  • Coordinate with EuroVO-AIDA Service Activities for these (prototype) implementations of these DAL, DM, VOQL standards to be consumed by VObs tools

Participation to the IVOA interoperability meetings to present EuroVO-AIDA findings and prototype and reference implementations of these DAL, DM, VOQL standards is taken into account in the Networking task WP2-4. The co-operatioon between partners amongst the JRAs is a networking activity undertaken in WP2-2 (EuroVO-AIDA Technology Forums).

Tasks

A number of work tasks have been identified to organise work within the WP7. The list follows accompanied by the Institution leading the task:

Deliverables

  • D7.1 (Month 15 - April 2009, ESA and other WP7 participants): WP7-JRA2 Intermediate report and associated prototypes.
  • D7.2 (Month 27 - April 2010, ESA and other WP7 participants): WP7-JRA2 final report and associated prototypes

Templates for EuroVO-AIDA deliverables are available here.
