Re: [soa-rm] RE: Resolving Various Policy Languages with Ontologies

I remember making some notes on the ontology section that I wanted to pass Frank's way but I've haven't gotten to that yet.  (However, I did just fix a nonfunctioning toilet, so I have my engineering accomplishment fix for the day :-) )

Anyway, I believe ontologies can be a very powerful tool in bringing together concepts from independent but overlapping domains (subdomains?) but we need to be careful to specify concepts (including needs) in the RM portion of or work without specifying solutions.  Thus, our list of what would be discussed in an RA portion continues to grow.

Subject: Resolving Various Policy Languages with Ontologies

Hi Duane,

The following is an e-mail dicussion I would like to

have with soa-rm group:

I have been reading WD-SOA-RM-09 to get an idea of the

terminology/concepts for resolving various policy

languages in a service oriented architecture. Section

2.2.3.2 of WD-SOA-RM-09 discusses the limits of

description.  Section 2.3.1.2 states that an ontology

can be defined to interpret strings and other tokens

in the data.  

In the discussions I've had about resolving various

policy languages in an SOA, I've hijacked the ontology

concept and applied it as a general concept for

resolving differences in policy languages.  

For example, if I have a service that uses XACML

policy and another service that uses EPAL policy, I

could resolve the differences between the two policy

languages using an ontology for both policy languages

at the policy decision point.

For section 2.3.1.2 of the WD-SOA-RM-09, does anyone

have any thoughts on expanding the concept of

ontologies beyond the service description's data

model?
