RE: SAF Primer

Hi Jeff,

 

This seems a very good step forward. I suggest that we all share the primer internally with our CIMI reps, first. When we have something more complete, we can consider how to cycle this back
 to CIMI WG for comment. How far along would you characterize our work to date? 

 

Thanks,

Paul

Subject: [saf] SAF Primer

 

More work completed on the DMTF CIMI section of the Primer.

The example below defines a Protocol (instead of just the Prescription), as ultimately that is what a CIMI SAF Catalog would include.

I think it is still valuable to see what the Prescription would look like, as well as defining a sample Symptom (shown at the bottom).

 

Next steps

-     
Provide example where CIMI monitor generates Symptoms and we provide Syndromes to detect.

-     
Setup a meeting with CIMI folks to discuss our progress.

 

Fyi – I will post to Oasis site (along with latest spec revisions) in a day or so.
