== Tendrils to the Services/Substrate WG ==

See [SubstrateOverlap Substrate Overlap], Notes From Substrate WG meeting 10/10/07

Summary of what Substrate needs from Services Group:
 * Need the workflow cases to extend down into the substrate.
 * GIMS (GENI instrumentation and measurement system), management hooks for researchers: need desires from Services.
 * Resource requirements: descriptions, granularity, parameters, etc.
 * Programmability requirements: what level of control, granularity, dependencies, interfaces, which resources are invoked and which are programmable?
 * What do requests look like, how are services bundled?
 * Are things invoked, or programmed?

Substrate provides to Services:
 * What resources are available to slices.
 * What level of programmability is possible on different components and their associated resources.

GIMS:
 * Measurement is a triangle between substrate/OMIS/services
 * Substrate supports collection of measurements and a place to keep the results
 * Services tells us how much and when, and then OMIS gets involved.
