Hi everyone,

Attached are the minutes from the OGSA Data WG F2F just recently held at NeSC, Edinburgh, 28-30 August 2006. These notes also include notes made by Allen. (A copy of the minutes is also on GridForge).

 

Many thanks to all those people that came along, and for all your excellent and valuable input.

 

 

Actions arising:

Sections in architecture document to be edited (plus appropriate bits to be put in appendix 3):

  1. Intro (section 1) - Mario
  2. Data Replication – Allen
  3. Data Access – Dais - Mario
  4. Data Access – ByteIO - Mario
  5. Data Transfer – Allen
  6. Data Description – Dave
  7. Data Federation – Allen
  8. Cache Services – Dave
  9. Data Storage – Stephen
  10. Metadata Catalogues – Dave
  11. Security – Allen

Note:    Appendix 1 listing specs – already done?

Appendix 2 summary of general interfaces – to be completed in final draft?

Appendix 3 mappings to specs – to be completed in final draft?

 

Scenarios:

  1. Joint Data/EMS scenario – Stephen.
  2. Stephen to recheck/update scenarios document following F2F discussions.

 

Issues to be addressed at OGSA level:

  1. When creating services how do you specify: (Dave)

-         Lifetime of Service

-         (Storage) Size

-         Default QoS requirements

-         Default (security) policies

-         Service Location (on which Server say)

-         Provisioning

 

  1. What about asynchronous operations and aborting requests? (Dave) (Suspend/Resume/Abort Request)

 

DMI discussions:

  1. Allen to send Data Transfer section to DMI-WG mailing list.
  2. Dave to send Data Transfer section to SRM group (GSM-WG).

 

GGF18:

  1. Dave to prepare Data Architecture slides.
  2. Stephen to prepare Data Scenarios slides (plus joint Data+EMS scenario?).

 

 

Cheers, Stephen.
