Thanks to the discussion on the mailing list in August, many points which need to be resolved are becoming clearer. Unfortunately, I don't have the answers to most of the points, and I currently lack the time / effort to delve into deep investigation.. OTOH I don't want to leave the micro-spec to be uncompleted and for more realistic discussion felt that blue-print ( or template if you like) of the spec would be needed. I am (very slowly) compiling the blue-print (based on the WS-Agreement Spec). In order to handle my limited English vocabulary, I am borrowing quite a bit of WS-Agreement Spec, so would expect the document to be authored by the original authors and any new contributors. Comments on how to proceed as well as improving the content is very much welcome. Also, for the glossary, I've included terms which had been defined in the original WS-Agreement Spec and is referred in the new spec. Is this necessary? or would citing WS-Agreement be enough?

Best regards, Philipp. -------- Original Message -------- Subject: [ogsa-wg] SLA terms for data services Date: Sun, 23 Sep 2007 08:20:17 +0900 From: Hiro Kishimoto Organisation: Fujitsu To: ogsa-wg Hi Andrew, Mark, and Steve, OGSA-Data WG has a suggested service level terms (they call policies) in their OGSA data architecture document. - Throughput: the number of access requests that can be satisfied per unit time. - Response time: the time allowed to satisfy an access request. - Availability: the percentage of time that the service must be up. - Recovery time: time allowed for the service to recover from a failure. - Data resiliency: a specification of the effort the service should make to ensure that data is not lost in the face of failures. - Access accuracy: if the primary source of some data is not available, how should the service act? Report an error? Find an alternate source (with potentially stale data)? Return partial answers? Another term for this policy might be degradation of answers. - Currency of data: can the data used by the service, and the data returned, be out of date? If so, by how much? I've put them on GridForge SLT design team wiki page for future reference.
