Formal methods for Evaluation of Interoperability & Maintainability?

Hi Gerard, I am talking about metrics like the one you had suggested previously: # of interfaces to be implemented to achieve interoperability with no message standard, some message standard and two-level systems. It is clear and easily computable and very objective. Perhaps it is worth studyi

Formal methods for Evaluation of Interoperability & Maintainability

Dear Koray, I am currently doing a PhD research on the topic of EHR Semantic Interoperability. So I am also very interested in formal ways of measuring system interoperability. As you have discovered, I also found relevant literatures are very few. But we could look for similar ones in other secto

Formal methods for Evaluation of Interoperability & Maintainability?

Koray, What metrics do you want to define? Gerard On Feb 11, 2008, at 10:40 AM, Koray Atalag wrote: > Dear All, > > I started this thread to get some feedback for finding methods/metrics > to test & validate maintainability and interoperability (of Archetype > based two-level apps). And I got

Formal methods for Evaluation of Interoperability & Maintainability?

Dear All, I started this thread to get some feedback for finding methods/metrics to test & validate maintainability and interoperability (of Archetype based two-level apps). And I got very nice ones; however for interoperability, apart from Gerard's interface numbers I did not get any and inte

Formal methods for Evaluation of Interoperability & Maintainability?

Hi Juanita, I would be honoured indeed :) Just a small remark I want to share with you all: After working in the field of clinical information systems (My own firm in Turkey established in 1996) I faced with the many problems we discuss here from firsthand and said enough, sold my shares and go

Formal methods for Evaluation of Interoperability & Maintainability?

Hiya Koray, It sounds like we may be able to collaborate in the future, which is fabulous. I'll be in touch Cheers Juanita Koray Atalag wrote: > Hi Juanita and others, > > It would be a great research topic and I think one that is needed very > badly from openEHR community. If I manage to fin

Formal methods for Evaluation of Interoperability & Maintainability?

Hiya, I'm thinking of doing some post doc work in this area later on this year. I thought you might find this reference useful too Koray: Smith B, Ceusters W. HL7 RIM: An incoherent standard. Studies in Health Technology and Informatics. 2006 August 2006(124):133-8. Cheers Juanita

Formal methods for Evaluation of Interoperability & Maintainability?

Hi Juanita and others, It would be a great research topic and I think one that is needed very badly from openEHR community. If I manage to find an appropriate research position, this would definitely fall within scope of my research as I already have necessary experience and data in endoscopy a

Formal methods for Evaluation of Interoperability & Maintainability?

Dear Koray, A metric from real practice: - Porting one application from its original database to Ocean Informatics EhrGate took two weeks. Including the production of a SOAP and .Com interface of the interface of Oceans product. Problems: - How do you put figures to the fact that no longer d

Formal methods for Evaluation of Interoperability & Maintainability?

Hi Gerard, a very useful document indeed...The approach is quite interesting and solid; no questions mathematically (at least in my MD mind!). I was thinking about brainstorming about finding some metrics (logical and feasible to experiment) to test those issues. Such as: Maintenance: compariso

Formal methods for Evaluation of Interoperability & Maintainability?

Hi, I want to learn how we can formally/objectively prove that Archetype based dual level development formalism alleviates problems of interoperability and maintainability. I was wondering if someone did or know of any such study which applies formal validation methods? Best regards, Koray At
