1 A PPARC funded project Tony Linde Programme Manager eScience meets eFrameworks 28 th April 2006 NeSC, Edinburgh

2 2 Tony Linde 28-Apr-2006eScience meets eFrameworks AstroGrid overview Virtual Observatory infrastructure “The VO vision can be summed up as the desire to make all archives speak the same language − all searchable and analysable by the same tools, all data sources accessible through a common interface, all data held in distributed databases that appear as one.” Andy Lawrence, 09/2003 AstroGrid approach Build infrastructure first VObs  Web Mix-and-match, plug-and-play, …

11 11 Tony Linde 28-Apr-2006eScience meets eFrameworks How do the VO components that implement these interfaces relate to each other?

12 12 Tony Linde 28-Apr-2006eScience meets eFrameworks DSA: Architecture SkyNode SIAP/ SSAP Web Svc (CEA) ADQL Translator Plugins: JDBC/Db FITS etc VOTable DSADSA

13 13 Tony Linde 28-Apr-2006eScience meets eFrameworks Registry We can access data but how do we know where it can be found? Knowledge of the location and nature of resources is critical for all this to work The AstroGrid Infrastructure supplies a Registry (IVOA compliant of course!) which contains this information Registry is searchable by humans and by machines.

14 14 Tony Linde 28-Apr-2006eScience meets eFrameworks Common Execution Architecture Why would we want CEA/UWS? Same reason we need universal access to data AstroGrid supports the concept of workflow Essentially, remote execution of special scripts or jobs Allows data access and processing to be undertaken at source or where the compute power lies The Grid concept! The AG Infrastructure helps make the details transparent, keeping focus on the science.

15 15 Tony Linde 28-Apr-2006eScience meets eFrameworks Workflow

16 16 Tony Linde 28-Apr-2006eScience meets eFrameworks Compute grid JES Registry Common Execution Connector Application as.exe file (local) Common Execution Connector Common Execution Connector Common Execution Connector Application as.exe file (grid) Application as.HTTP service Application as Java class

17 17 Tony Linde 28-Apr-2006eScience meets eFrameworks MySpace If all this happens remotely, where do the results end up? Distributed data access and processing requires distributed data storage MySpace is the AstroGrid solution VOSpace/VOStore under review at IVOA Distributed, virtual data storage that appears to the user as a homogeneous collection of files Database tables coming soon!

20 20 Tony Linde 28-Apr-2006eScience meets eFrameworks AstroGrid Actors Astronomers Incl PIs, management structure, … Instrument operators, … Data curators Publishers Administrators Systems managers Developers Standards definers …

21 21 Tony Linde 28-Apr-2006eScience meets eFrameworks AstroGrid and eFrameworks: Issues Security Shibboleth authentication:  Single-signon Authorisation  Common policy requirements? Service discovery Resource registries  Need for commonality?  Will others need to get at astro resources? Common identifiers?

22 22 Tony Linde 28-Apr-2006eScience meets eFrameworks AstroGrid and eFrameworks: Other Issues Service execution Workflow Shared storage Accounting Naming! e.g. VO Bottom line Standards & interoperability How do we get W3C, GGF, IVOA, IE & project standards to work?
