Re: [cosmos-dev] Status of Datacenter SML example

joel,

would you be kind enough to provide an example of what you are looking for?  

from reading your note, it sounds to me that you are making the same leap as me, e.g. facets are roughly equal to a capability.  and you want to have somehting like the RMD where you can "decorate" a property with additional info, a la metrics.  it would be good to get something like this, and a use case in front of the RM people.

as for a use case, we would want to tie this together with a CMDBf scenario, e.g. i need to query a CMDB for information about a resource so that i can understand which properties i want to monitor or something like that.

if you could structure an example with the data center, then ali and i could review it with the folks from IBM that are working on data model activities.

Joel,

I'm not aware how the CML workgroup is progressing.  You'll have to look around to see if the workgroup is taking input from the general public.  The example you note below is a language detail that belongs more in SML than CML.  The latter is just instances of SML used to model resources.

Thanks,

Thanks Ali. I really like the facet concept, both as an organizing principle and as a means of capturing and retaining separate concerns. I hope it makes it into CML.

 

Are any other conventions going to go into CML (that you can talk about)? For instance, XMLSchema and SML give a model designer the ability to denote identity requirements – would it be possible to standardize on some additional annotations to decorate models to distinguish between descriptive attributes and time-sensitive attributes (for example)?

 

Cheers,

Joel

Hi Joel,

The concept of facets is purely COSMOS.  There is a possibility for a similar concept to be incorporated in Common Model Language (CML) but no such thing exists in SML.

Joel,

To get some examples for all the various SML syntactical elements, you should check out our test suite.  Go to testing/org.eclipse.cosmos.rm.validation.tests and look in the test resources folder.

I'll have to look into your facet question and get back to you.  Valentina and Harm created the data center example, and to be honest, I never understood the purpose of the facet elements we have in there.

Hi David,

 

Thanks for the reply. I'm working on an internal project (that has taken me away from COSMOS and appears to be bringing me back) that involves ontology extraction from things like SML models – so I figured hey, why not start with our COSMOS example?

 

A couple of other things I noticed in there – we're not making use of any of the identity capabilities in the SML schema (or from XSD, for that matter). Any reason for that? Can I get a xsd:unique up in here? ;-)

 

Also, is the facet concept purely a COSMOS thing? I was under the impression that it was part of the SML effort, but I don't see it anywhere in the spec. The concept seemed to align well with WSDM's capability model, and fits well the whole separation of concerns thing, but it appears to be a best-practices recommendation. Is that the case?

 

Thanks,

Joel

Hi Joel,

Yes, they are supposed to validate.  The project itself should contain correct SML code, and should be up to date for the 1.1 level of the SML spec.  That said, it appears our validator has some problems currently with that sample.  We have an open defect targeted for i11 that will hopefully address some or all of these issues:

http://bugs.eclipse.org/228223

Add yourself to the cc: list if you want to keep informed on progress.

Might I ask what you're looking at SML for?  I didn't know you had an interest in it.

Regards,
David

[cosmos-dev] Status of Datacenter SML example

 

 


   




Howdy y'all.

 

Can someone tell me what the status of the org.eclipse.cosmos.rm.example.datacenter project is? I'm (finally) trying to get back into COSMOS, and I need some sample SML documents to play with. When I run the datacenter documents through the Resource Modeling validator I get a number of errors (occasional missing type constraints, doesn't like xml:lang, can't find it:facetType(!)). Should these documents validate?

 

Thanks,

Joel
