I am puzzled by the way the QVT proposals describe their syntaxes. Most of the documents contain an _abstract_ syntax and a _concrete_ syntax. What is the...
Hi Perhaps the simplest distinction is in terms of audience. The concrete syntax is what programmers program in. Programmers are not often interested or aware...
... This statement implicitly suggests that PIMs may not use profiles. In my vision profiles should be used in PIMs as well as in PSMs. The difference between...
Responding to Bonestro... ... I suspect that wasn't the intent. One needs a profile for the PIM; the notation itself is an element of the profile. This is...
... Also, the use of a profile in the PIM allows you to approximate a DSL (Domain Specific Language), thereby permitting expressing the domain model more ...
I hope when you talk about needing profiles to define the language of your PIM, you don't mean that's the only way of specifying your DSL? Profiles are all...
Hi, While I was looking around the internet for different sources of information on MDA I realized that there is no MDA community website around yet. This list...
Hi, one problem might be that the real cutting edge MDA tool are very expensive thus limiting the userbase. "Doing" MDA in one of these tools is quite...
... Notice I said "approximate", not "replace". ... DSLs need not even be limited to MOF. After all, that still forces the DSL to be OO. There are many non OO...
Responding to Kofman... ... The main reason is that MDA is still pretty much in the specification stage so there are few concrete MDA implementations that are...
... Yes you're right. Sorry I wasn't thinking when I wrote that. However, its still true that MOF may not be the most appropriate formalism for complete ...
Hello Felix - ... I'm not sure what tools you have in mind, or how you define "cutting edge" and "very expensive", but the PathMATE toolset that we offer is a...
Felix I agree with Peter: not all the tools are expensive. ModelScope, which supports model execution and is aimed at transactional IT systems, is also...
... the ... its ... complete ... With that, I totally agree ;-) Having been a big fan of the OMG standards for quite some time, I wonder whether they have not...
What is "the expected outcome of the QVT RFC (sic)"? (Admission: I am involved with one/some of the submission teams, and am interested to see what users...
Responding to Tilkov... ... FWIW, I personally strongly agree. UML already has too much specific implementation stuff in it (e.g., OCL, which is a particular ...
Hi All ... Which is why QVT is so important. It allows for transformation between meta-model compliant models. As UML collapses/gets superseded by new XML...
... Sorry if this came across as a critique of the submissions - I have skimmed through them (at least through what was available something like 6 months ago),...
hi,all I don't know how to use the xmi-addin in ROSE, my Rose version is 2002 Can anybody pls tell me the usage of "MOF 1.3 XMI import/export" and "UML 1.3 XMI...
Perhaps you're right. Personally, I haven't an awful lot to do with UML beyond using it as a big test case for MOF tools, and I find that its infinitely more...
Responding to Willink... ... I afraid don't follow this. I don't see XML ever replacing UML; it's apples and oranges. XML is a static data description while...
Hi ... I think we're agreeing. Of course XML doesn't replace UML. XML just provides the technology space in which the information in a UML model can be...
... To my understanding MDA recognizes profiles as one mechanism; others include model marking and metamodel-based languages. The real question is then which...
Responding to Willink... ... OK. ... I was the one who doesn't think OCL should be in UML. That's precisely because OCL is a concrete syntax. UML should...
Hi Stefan .. ... Baggage is unfortunate but not necessarily a disaster. I find that I use a much simpler subset of MOF for meta-modelling. Who needs...
Dear Sir/Madam, I am currently doing a research on the topic of "A New Metrics Oracle for Component Based Software Engineering (CBSE)". I am currently at the...
I don't understand. UML has never really been about semantic meta-models, but rather about a diagramming notation (read: concrete syntax). Recent efforts have...
My biggest gripe with UML/MOF 2.0 is that, although not a lot has really changed, the spec documents have changed totally, and are now a nightmare to navigate...
