  • Re: Web Based nORMa

    Me and my friend Thomas have been working on an external orm tool for about 5 months now.  About 2 months ago he started a silverlight implementation and since the application is well layered it has been very easy to port.  We don't have a working demo yet but the website is http://www.ormdesign.com

  • Re: CogNIAM and ORM as business practices of SBVR

    Dear John, Thanks for your clear description of semantic and speech communities in SBVR and the relationship to UoD. I would propose we extend it a bit by the following: SBVR distinguishes three levels: a. Ground facts b. Domain specific conceptual schema c. Generic conceptual schema In SBVR the union of b+c is called Conceptual ...

     Ken, The published specification of SBVR is dtc/08-01-02. That's the one you should be reading, although the definition of ‘body of shared meanings’ hasn’t changed much since dtc/06-03-02. It is now: “set of concepts and elements of guidance for which there is a shared understanding in a given semantic community” A body of shared ...

    Hi John, Thanks for your explanation. My response follows. Cheers Ken A semantic community is a group of people. Thanks for the clarification. Mea culpa! In my haste to answer the post, I had assumed that the definition of each term was self contained. I can now see that there is a structuring of terms. Their body of shared meanings ...

      Ken,A semantic community is a group of people. Their body of shared meanings is what corresponds to a Universe of Discourse. People can join the community, or stop believing and leave the community, without changing the body of shared meanings. A speech community is a part of a semantic community – the people in the semantic ...

  • Re: CogNIAM and ORM as business practices of SBVR

    Terry, Thanks very much for your lucid description of ORM, CogNIAM and SBVR. I agree with you that a common core model is a very worthwile effort for the fact orientation community. I like in particular your words "useful subsets of them". I know quite a few fact orientation users who welcome such an approach. I assume that both of ...

  • Re: CogNIAM and ORM as business practices of SBVR

    Terry, Of course I agree that "symbols are not communities". (The label is not the thing!) However, I was interpreting the SBVR standard from the semiotic perspective. The SBVR standard lists the term "semantic community" and gives the following definition:       "(a) community ...

  • Re: CogNIAM and ORM as business practices of SBVR

    ORM, CogNIAM and SBVR are all fact-oriented approaches, and it is possible to define a common core metamodel based on an intersection of these approaches, and hence enable translation between useful subsets of them. ORM and CogNIAM have much in common, and the difference between them is not so much one of formality (as both can be given a ...

  • Re: CogNIAM and ORM as business practices of SBVR

    Hi Roel, I don't know anything about UI and perFact so I can't comment. However, as I see it, although superficially similar, NIAM and ORM have a significant difference. For me, the crucial difference is that ORM meets the criteria required of a formal language. (See Terry Halpin's 1989 PhD thesis, ...

  • Re: CogNIAM and ORM as business practices of SBVR

    Hi Ken,  I'm not very familiar with ORM yet, but since 1989 busy with NIAM, UI and perFact. I suppose ORM is not that different is it's foundation. So I expect that any SBVR construct can be represented in some way in SBVR. I can imagine that ORM does not have a symbol for all of the present constructs of SBVR. The above ...
