OID once more

Technical (archive)

Two simpel questions, though the answer may be complicated

1) Is there an OID which can be used if there is no OID known, f.e. 0.0.0.0.0

2) I work for a comany which wants to use the insurance-number of a patient
for a special goal. It only wants the Insurance-number.
What is the best way to present this?
Normally, the Insurance-number is a part of the Identity which is a list of
II, but the items of that list do not contain meta-information. How can an
insurance number be recognized?

Dear Bert,

As you know, I am not technical enough to respond to you on OID construction, but I wanted you to know that I am sensitive to the OID-heavy nature of 13606 at present, and will look to ways to ease the implementation burden. I suspect your concerns will be shared by many.

With best wishes,
Dipak

for what it is worth, I think that HL7 has not modelled identities properly; using only II for everything assumes that every organisation in the world will have OIDs and be using them for all the things they issue. I really doubt that this will ever happen, but even if it does, it won't be in place for another 10-20 years. In openEHR we differentiate between OBJECT_ID (ids for informational things) and DV_IDENTIFIER, a data type for identifiers of real world obejcts, like drivers licenses and insurance; this latter type contains the attributes you need to indicate the organisation etc.See the data types at http://www.openehr.org/repositories/spec-dev/latest/publishing/architecture/reference_model/data_types/data_types_im.pdf.
