2. WP8 – Assessment of emerging technologies EuroVO-AIDA – First periodic review – 24 April 2009 Françoise Genova, Project Coordinator WP Objectives Assess the potential usage of emerging technologies of interest to the VO in technical areas where partners are involved Domains of interest –Web 2.0 for data centres (CNRS) –Semantics and ontologies (INAF) –Data mining (UEDIN)

3. WP8 – Assessment of emerging technologies EuroVO-AIDA – First periodic review – 24 April 2009 Françoise Genova, Project Coordinator WP8 milestones & deliverables Common milestones to all JRAs –Technology Forums –IVOA Interoperability meetings No deliverable during the reporting period D8.1 WP8-JRA3 intermediate report and associated prototypes CNRSApril 2009 D8.2 WP8-JRA3 final report and associated prototypes CNRSApril 2010

4. WP8 – Assessment of emerging technologies EuroVO-AIDA – First periodic review – 24 April 2009 Françoise Genova, Project Coordinator Interfaces with VO-TECH The activities are interfaced with Design Studies performed in the VO-TECH project (2005-2008, extended to June 2009). As foreseen, the detailed EuroVO-AIDA work programme has to take into account VO-TECH findings - agile strategy to maximize impact Web 2.0 assessment has been fully active during Year 1. The two other assessments will be mostly active during the next reporting periods.

6. WP8 – Assessment of emerging technologies EuroVO-AIDA – First periodic review – 24 April 2009 Françoise Genova, Project Coordinator Rationale The widely used CDS services (more than 200.000 requests/day) are an excellent testbed for assessing Web 2.0 technologies Several aspects –Assess technology and human cost associated to quality management of implementing the possibility for users to post annotations –Services mash-up –Assessment of Flex technology

7. WP8 – Assessment of emerging technologies EuroVO-AIDA – First periodic review – 24 April 2009 Françoise Genova, Project Coordinator Annotations Hot topic - High interest and interesting input gathered during the second Technology Forum Extensive discussion with service managers and CDS scientists for detailed requirements Will be released soon in one of the services (SIMBAD) as a real-size prototype. Usage and content will be carefully assessed.

8. WP8 – Assessment of emerging technologies EuroVO-AIDA – First periodic review – 24 April 2009 Françoise Genova, Project Coordinator Requirements No a priori moderation User identification (userid/password/email) Annotations of the different service contents –Information about astronomical objects and bibliographic references (SIMBAD) –Catalogue/Table descriptions, catalogue entries (VizieR) Possibility to require an action from CDS (e.g. error correction, update, etc)

12. WP8 – Assessment of emerging technologies EuroVO-AIDA – First periodic review – 24 April 2009 Françoise Genova, Project Coordinator Expected results Test of the hypothesis, in particular –Users will be interested –No need for moderation Assessment of the possibility to replace the current CDS hot-line by allowing different types of input –Public –CDS only –Action from CDS required

13. WP8 – Assessment of emerging technologies EuroVO-AIDA – First periodic review – 24 April 2009 Françoise Genova, Project Coordinator Service mashup A single portal for heterogeneous data provided by different services Urgent assessment to facilitate the usage of CDS services Finally developed on VO-TECH + CDS funds Query of the three CDS services, summary of available results, links to the services, re-use of the results of one service in another Very high interest at Baltimore Interoperability meeting Test of the usage of Ajax – very well adapted to aggregate contents First implementation of user storage space at CDS (assessment of real life usage of iRODS –WP6)
