1. DAIT (DAI Two) NeSC Review 18 March 2004

2. Description and Aims Grid is about resource sharing Data forms an important part of that vision Data on Grids: May be geographically distributed Storage technology and formats are not homogeneous Need to dynamically bind to data sources on demand Grid enabled data resources Discoverable through published metadata Robust against variations in standards Easy to aggregate, federate and manage

3. Issues Important facets that need to be considered: Metadata  Data structure, access policies, data content, provenance, physical properties, etc. Registries required for resource discovery/matching  Allow dynamic binding to data sources based on provision of metadata Different modes of operation/delivery  JDBC, ODBC, bulk data transfer, third-party data transfer, incremental data transfer, delayed data transfer Security mechanisms  Authentication, authorisation, accounting, audit, privacy/encryption Data transformation processes  Reformatting, compression Facilitate transaction / workflow participation arrangements

4. Goals for DAIT Keep the OGSA-DAI name for DAIT Aim to deliver application mechanisms that: Meet the data requirements of Grid applications  Reduce development cost of data centric Grid applications  Provide consistent interfaces to data resources  Functionality, performance, etc. Acceptable and supportable by database providers  Provide a standard framework that satisfies standard requirements  Trustable, imposed demand is acceptable, etc. A base for developing higher-level services Distributed query processing  http://www.ogsadai.org.uk/dqp Data federation

5. Status Project started 1 st October 2003 Funding for 2 years EPCC, NeSC, Newcastle, Manchester Industry Collaboration IBM engaged at start of 2004 Oracle and Fujitsu on Programme Board People: 5 FTEs at EPCC, 5 FTEs at IBM 1 PDRA at each of NeSC, Newcastle, Manchester Releases: 6 monthly major releases Next release scheduled for April

7.

8. Points to Note Most projects seem to be biological Feedback from users largely positive Need more Hope to allow user contributions Need to establish a policy/framework for this Engage more with User Community Meetings scheduled for later this year  OGSA-DAI users meeting at NeSC in April  OGSA-DAI mini-workshop at AHM 2004  OGSA-DAI tutorials at various meetings/locations

9. Protecting Your Users Very rapidly moving field Technology changes Standard changes Middleware changes Need to ensure: Technology adopters investment in OGSA-DAI is protected Shielded from future change Positives: Document interface helpful Client toolkit  Tech Preview in R3.1

10. DAIT Roadmap R3.1Feb 2004 - Technical Preview part of R4 User Group: inaugural meeting – April 7 th 2004 R4.0April 2004 Performance & monitoring Additional DBMSs supported (SQL Server, Postgres) DBMS management operations  archive, restore, bulk load File access Client libraries Installation wizard User support, courses, training material, performance report

11. DAIT Roadmap 2 R5 October 2004 Alignment with DAIS Spec  Assuming specs settle post GGF11 Integration into Globus Toolkit  WS-RF friendly Basic Web Services friendly as well? R6 April 2005 R7 October 2005 Increased data integration tools Functionality driven by user group
