HL7V2.x and Non-MLLP/ HL7V2.x and CDA

After working for 10 years for a company i resigned my job last month and joined a new job last week.Iam not in a position to post anything new due to lack of time and lack of space(shifting to a new home as well). I will do so from August when i hope to get some decent time and space in my new home.But i could not resist posting two quick comments for those who came to my my blog with two search words and terms

The first one is for the person who came to my blog with the long search query term “is there any other way of transporting hl7 message apart from mllp”. Yes there are , there are two alternative options to sending HL7V2.xmessages over MLLP one is sending it over HLLLP; For details see my post on HL7V2.x and Low layer protocols
http://healthcareinformatics3000feet.blogspot.com/2007/12/hl7v2x-and-low-layer-protocols.html

The other option is to use ebXML; use the normal ebxml header and put the hl7v2.x message in the MIME part; for discussions on ebXML structure see my ebXML and HL7V3 posts.

The second comment is for the guys who came with the term HL7V2.x and CDA , I just want to mention that From the perspective of a V2.x CDA document is a multimedia object, to be exchanged as a Multipurpose Internet Mail Extensions (MIME, RFC 2046) package, encoded as an encapsulated data type (ED).In V2.x, CDA documents are to be exchanged in the OBX segment, in any message that can exchange documents (such as MDM). Within the OBX segment, the MIME package is placed in OBX.5 (Field 00573 Observation value), encoded as a V2.x encapsulated data type.

I will write in detail later on the above two in my next posts.

The Problem of Abstraction in Definitions of Data Objects

I think there is a major problem in not being able to understand and work with different levels of abstraction.  By "abstraction" in this sense I mean one concept system that somehow describes or defines (not merely relates to) another concept system.  I think this is a big problem for definitions in data models. Let us take an example in a retail business such as mortgage banking: Customer Name.  Customer Name exists in the business.  They use it all the time.  Maybe it is sometimes called Borrower Name, but the concept is the same.  This is the Level 1 abstraction. Now let us think of data values in a column in a table that holds Customer Name.  These data values are stored as a code of 1's and 0's.  Of course these bits are rendered into something we can read.  However, this is not the same as the Customer Name in the business.  I worked for a place where they prefixed the name of anyone who had recently left with "ZZZ"....

The Humpty-Dumpty Principle in Definitions

In dealing with empty concepts, we came across the issue that if somebody uses a term that potentially has an unintelligible definition, they are likely to defend themselves by quickly making up some kind of definition.   I strongly suspect that in such cases, the usage of the term will be inconsistent with the definition.  Which brings us to Humpty-Dumpty. Lewis Carroll (Rev. Charles Lutwidge Dodgson) is best known for his children's' books Alice's Adventures in Wonderland and Through the Looking Glass .  It is in the latter that Humpty Dumpty - an argumentative egg perched on a wall has the following exchange with Alice: 'And only one for birthday presents, you know. There's glory for you!' `I don't know what you mean by "glory",' Alice said. Humpty Dumpty smiled contemptuously. `Of course you don't -- till I tell you. I meant "there's a nice knock-down argument for you!"' `But "glory" doesn't mean "...
