Part 1 State of the VO

The VO vision

5 27-Sept-2004Andy Lawrence : IVOA workshop, Pune VO : Generic Science Drivers data growth : volume and richness desire to work on-line multi-archive science large database science empowerment

6 27-Sept-2004Andy Lawrence : IVOA workshop, Pune Data re-use : a market fact HST : more retrieval than ingest

multi- views of a Supernova Remnant Shocks seen in the X- ray Heavy elements seen in the optical Dust seen in the IR Relativistic electrons seen in the radio

needles in a haystack b - faint moving object is a cool white dwarf - may be solution to the dark matter problem - but hard to find : one in a million - even harder across multiple archives

9 27-Sept-2004Andy Lawrence : IVOA workshop, Pune VO : Technical Drivers data rate, storage and flops : x 1000 /decade but device bw x 10/decade search engines next to the data backbone network bw ~Gbps but end-end bw ~10Mbps analyse in situ : shift results not data

10 27-Sept-2004Andy Lawrence : IVOA workshop, Pune network development higher level protocols ==> transparency TCP/IP message exchange HTTPdoc sharing (web) grid suiteCPU sharing XML/SOAP data exchange

11 27-Sept-2004Andy Lawrence : IVOA workshop, Pune the VO concept web all docs in the world inside your PC VO all databases in the world inside your PC

VO structure

13 27-Sept-2004Andy Lawrence : IVOA workshop, Pune what its not not a monolith not a warehouse

14 27-Sept-2004Andy Lawrence : IVOA workshop, Pune VO framework standards inter-operable data inter-operable software modules no central VO-command

15 27-Sept-2004Andy Lawrence : IVOA workshop, Pune publishing metaphor experiments/facilities are authors data centres are publishers VO portals are shops end-users are readers VO infrastructure is distribution system.

16 27-Sept-2004Andy Lawrence : IVOA workshop, Pune work to do agree standards build software glue build VO-aware tools build VO-aware data services

Standards, Standards, Standards

18 27-Sept-2004Andy Lawrence : IVOA workshop, Pune International VO alliance (IVOA)

19 27-Sept-2004Andy Lawrence : IVOA workshop, Pune IVOA activities development of standards technical working groups bi-annual interoperability workshops exchange of best practice formal process modelled on W3C

Progress towards the VO

21 27-Sept-2004Andy Lawrence : IVOA workshop, Pune IVOA standards key standards so far protocols for tables, images, spectra resource and service metadata definitions standardised query language provisional semantic dictionary standardised grid and web service interfaces coming up ? generic data model, identification, semantics

22 27-Sept-2004Andy Lawrence : IVOA workshop, Pune glue accomplishments prelim versions of key components Registry, Workflow, Sign-on, VOSpace several crafted-demos some real science done first users starting to play AVO SWG; AstroGrid AGSAG NVO summer school

23 27-Sept-2004Andy Lawrence : IVOA workshop, Pune services and tools data centres upgrading worldwide many data centres now exporting VOTable real data services in SkyQuery and others standard tools being VO-ised Aladin, DS9, Sextractor, etc new tools : VOPlot, SEDTool, TOPCAT ambitious services : AusVO grid-visualisation

IVOA issues

provocative finale

37 27-Sept-2004Andy Lawrence : IVOA workshop, Pune are we getting there ? data interoperability resource interoperability data integration single sign on complex jobs

38 27-Sept-2004Andy Lawrence : IVOA workshop, Pune are we getting there ? data interoperability good progress VOtable, SIAP, SSAP will need refreshing

39 27-Sept-2004Andy Lawrence : IVOA workshop, Pune are we getting there ? resource interoperability good progress RSM doc, harvestable registries progress on WS interfaces prelim storage sharing (MySpace)

40 27-Sept-2004Andy Lawrence : IVOA workshop, Pune are we getting there ? data integration not really there plain proximity SkyQuery best attempt really science / algorithm problem not IT need real semantics - not just types UCNs; units; grammar concentrate on operations not philosophy who is the rescue team ?  UCD++ ? DM ? Semantic Web ?

41 27-Sept-2004Andy Lawrence : IVOA workshop, Pune are we getting there ? single sign on liimited IVOA attention (GWS-WG) primitive AstroGrid deployment need to cohere with rest of academia Shibboleth looks like the winner

42 27-Sept-2004Andy Lawrence : IVOA workshop, Pune are we getting there ? complex jobs : workflow negligible IVOA attention simple AstroGrid deployment Bio way ahead  talking about patenting workflows
