wiki1593: GINPhase1

GIN Phase 1 for services comprises the following agreements:

Authentication is via x509 credentials.
- Caveat: some grid software does not yet properly handle RFC 3820 compliant proxies.
Credentials used should come from Certification Authorities recognised by the IGTF
- Caveat: some participants credentials come fron non-IGTF-accreditted CAs. Pairwise agreements in place to work around this.
Authorization attributes (if any are recognized) are transmitted via VOMS extensions to the x509 credentials
- Caveat: none of the participating grids enable solely attribute based authorization yet. VOs need to make their membership lists known in advance.
VO Naming convention is described in the GIN VO Naming document
- Caveat: EGEE configuration maintainance software does not currently properly deal with VO names containing a dot (.).

GRAM and WS-GRAM islands for job submission are being established
Grids offering Job Execution services should offer a persistent Community Software area where groups can install persistent code for their applications.

Each grid's internal Information system will act as a buffer/translator for accessing information about GIN participating services
A subset of the GLUE schema is being used as the common description schema for GIN services
