Introduction
Data Replication
Data Transfer
Data Integration
Data Staging
Personal Data Profile
Data Discovery
Data Storage
Data Federation
Two key issues
Data transfer
Protocols
Control (is a separate service required?)
Out of scope: automatic transformations
Policy specification
WS-Agreement / WS-Policy?
Consistency management policies
Security policies
Performance policies
Next steps
OGSA F2F next week
Revise both documents for consistency
Present and discuss
GGF16, Athens
Present documents to wider community
Discussions with GFS
Aim for submission soon after
Meanwhile…
DAIS, ByteIO already submitted
Then…
Version 2.0?
