3. IVOA priority The IVOA is about enabling astronomical research Fulfilling the requirements from the astronomical community has key importance Excellent work on standards done up to now Near term: get useful tools & services to astronomers now Dave De Youngs talk Fabio Pasian - Concluding Remarks - IVOA Interop, Strasbourg, 24-29 May 09 3 Monday 25 th May 2009

4. A turning point... Take-Up Committee meeting Take-Up discussion Fabio Pasian - Concluding Remarks - IVOA Interop, Strasbourg, 24-29 May 09 4 Tuesday 26 th May 2009 Exec meeting Wednesday 27 th May 2009

5. ... and a change in pace... Fabio Pasian - Concluding Remarks - IVOA Interop, Strasbourg, 24-29 May 09 5 On the initiative of the Take-Up Committee, proposal identifying a prioritisation path for the IVOA to follow, based on 3 elements: a) TAP to be finalised within summer 09 as a powerful tool for data access; b)generation of a Use Cases Group planned to produce a set of example queries at a level of completeness sufficient to ensure that good enough data queries are possible; c) Observation Data Model and UTypes to be brought to a higher priority and aimed to be finalized by May 2010 Interop. To move forward, this proposal needs the support from major data producers.

6. ... approved by Exec Looping mechanism between the Exec and the TCG, with the involvement of the relevant WGs : Use cases set requirements vs standards and protocols, which shall be pushed to an acceptable level with the support of the projects, which are committed to collaborate in this effort. Use cases shall then be refined and prioritised. This mechanism shall not follow a waterfall approach, but rather be iterative and interactive, especially in the definition of requirements. Fabio Pasian - Concluding Remarks - IVOA Interop, Strasbourg, 24-29 May 09 6

7. ... approved by Exec Furthermore, this mechanism shall not force the WGs to derail from their normal way of working: it is focussing on additional non-usual prioritisation work (c/o Exec and TCG). Several WGs, in particular DAL and DM, will be involved. Data centres should also be involved to define the level which can be implemented. A list of interdependencies and interrelations among standards will be produced. Fabio Pasian - Concluding Remarks - IVOA Interop, Strasbourg, 24-29 May 09 7

8. Highlights (Positive) reaction from WGs Initial collection of Use Cases TAP ! v1.0 is within reach (at long last!) using both ADQL and PQL – RFC to start 5 th June VOTable v1.2 (including connections to TAP and STC) – RFC to start 1 st July UTypes draft issued Fabio Pasian - Concluding Remarks - IVOA Interop, Strasbourg, 24-29 May 09 8

9. Highlights SIAP v1.1 in RFC – work started for v2.0 SAMP success VOSpace essential capability Mature applications Registry Curation Tools awareness of their importance – for Data Centres to manage/cleanup – for users to find the data they are Special meetings gathering interest Started thinking about metrics Fabio Pasian - Concluding Remarks - IVOA Interop, Strasbourg, 24-29 May 09 9

10. Issues Do what we have decided – schedule – resources Quality of data and services,... Logging M etrics Fabio Pasian - Concluding Remarks - IVOA Interop, Strasbourg, 24-29 May 09 10

11. What IVOA is about We are about sharing, reciprocity, consensus. – To reach agreements, compromises are needed. Rather than showing strong leadership, anyone of us should act as a facilitator. – Being a facilitator is a sign of leadership! This was done during this Interop. You guys have been great! 11 Fabio Pasian - Concluding Remarks - IVOA Interop, Strasbourg, 24-29 May 09

12. Next Interop: Garching 8 th – 13 th Nov 2009 See you there !
