Papaspryou, A. Savva, D. Fellows, via JSDL-WG Abstract: The purpose of this document is to specify the syntax and semantics of the Activity Instance Description. An "activity", in this context, is a unit of work to be executed on a distributed system. It can be a job, a task, a data processing operation, a data access operation, an application execution, a program execution or a Web Service invocation. The Activity Instance Description captures the information related to this unit of work. Systems built based on this specification can provide a holistic view of an activity, for example for monitoring, auditing or checkpointing purposes. The specification pursues two different but complementary objectives: (i) it specifies a generic and extensible framework to capture the information related to an activity; and (ii) it specializes this generic framework using a number of Open Grid Forum specifications. -- Greg Newby, OGF Editor Dr. Gregory Newby, Director of the Arctic Region Supercomputing Center Univ of Alaska Fairbanks-909 Koyukuk Dr-PO Box 756020-Fairbanks-AK 99775-6020 e: gbnewby@alaska.edu v: 907-450-8663 f: 907-450-8603 w: people.arsc.edu/~newby
