NeSC Review
18 March 2004

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

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

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

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

R3.1
Feb 2004 - Technical Preview part of R4
User Group: inaugural meeting – April 7 th 2004
R4.0
April 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

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
