WP 7 - JRA2 - Data Access Protocols and Data Models EuroVO-AIDA – Final review – 5 October 2010

Work Package 7 - JRA2

Data Access Protocols and Data Models



WP7 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 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.



WP7 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.

– 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 resourcesCoordinate with EuroVO-AIDA Service Activities for these (prototype) implementations of these DAL, DM, VOQL standards to be consumed by VObs tools[…]

WP7_T10

Work has focused on some of these tasks, because of their importance for the partner activities and of the (evolving) international context and priorities

Detailed report given in March 2010 Review Presentations



D7.2: WP7-JRA2 final report and associated prototypes

• Initially planned for April 2010

• Released in August 2010– after the IVOA Interop meeting in May in Victoria, Canada



Definition of the IVOA Architecture

• IVOA Technical Coordination Group meeting in Victoria, Canada, May 2010

– http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/TCGMeetingAgenda201005

– 11 participants from Euro-VO AIDA projects, out of the 16 present

• Major Milestone for IVOA• IVOA Architecture Note being written by the TCG

– To be released in October 2010



IVOA Architecture Level 0









ObsTAP Service in IVOA Architecture



ObsTAP Service relationship with other IVOA standards



SED Builder science use case in IVOA Architecture



SED Builder science use case relationship with other IVOA standards



IVOA (DAL/DM/VOQL) standards which have become Recommendations during Euro-VO AIDA

• Simple Cone Search (SCS) in February 2008• Simple Spectra Access Protocol (SSAP) in February 2008• Characterization Data Model (CharDM) in March 2008• Astronomical Data Query Language (ADQL) in October 2008• Simple Image Access Protocol (SIAP) 1.0 in November 2009• Table Access Procotol (TAP) in February 2010• SLAP 1.0 and SSLDM 1.0 are being in IVOA TCG Review, should soon

become Rec.

• Strong Euro-VO involvement on these activities– IVOA TCG, DAL, DM, VOQL WG chairs and vice-chairs from Euro-VO AIDA

partners– Many Euro-VO partners members authors and co-authors of these standards



Further IVOA (DAL/DM/VOQL) standards under development during Euro-VO AIDA project

• Simple Image Access Protocol (SIAP) 2.0• Footprint Access Protocol• Parameterized Query Language• Observation Core Data Model• Observation Provenance Data Model• Characterization Data Model (CharDM) 2.0• Spectrum Data Model 2.0• Photometry Data Model• UTypes Data Model• Units Data Model• Simulations Data Model• Simulations Data Access Layer
