[Oslc-pm] Use of pm:availabilityStatus

[John Arwe]

The resource shape governs occurrence constraints w/in PM.   It says 0:* 
pm:availabilityStatus 
The intent of the cited text is: 
- if you have >= 1 pm:availabilityStatus predicate, then 
-- all objects must be non-conflicting .... typically some are refinements 
of others; the singleton case is trivially non-conflicting.
-- at least one of them must be from the PM vocab ... so clients knowing 
ONLY the PM spec are "guaranteed" to find at least one value useful

Hi all, 

From the spec: 
OSLC Performance Monitoring service providers can identify the 
availabilityStatus using references to property values in the OSLC 
Performance Monitoring vocabulary or to property values that are not in 
the Performance Monitoring vocabulary (i.e. in the service provider’s own 
vocabulary). It is expected that the availabilityStatus values will be URI 
references to property values, but inline resources defining the 
availabilityStatus property values are also valid. Performance Monitoring 
service providers MUST use at least one availabilityStatus (Performance 
Monitoring Record) defined in the OSLC Performance Monitoring vocabulary 
in addition to any availabilityStatus values not in the Performance 
Monitoring vocabulary. 

The additional property values for pm:availabilityStatus are: 

URI        Description 
http://open-services.net/ns/perfmon#NotRunning        Not running in its 
host environment 
http://open-services.net/ns/perfmon#Running        Running in its host 
environment 
http://open-services.net/ns/perfmon#Unknown        Unknown 

======= 

I think what we're saying here is that providers can define their own URIs 
for the status and that a resource should always have at least 2 
pm:availabilityStatus , 
one of which is set to #Running/#NotRunning/#Unknown. 
Am I reading this correctly ? 

Thanks ! T
