RE: X12 vs: XML File Sizes
Martin,
You might look at some of XML work HL7 has done (www.hl7.org).

Guess I should have made that clarification. Sorry.
I wasn't talking about trying to use XML for transaction purposes, just
thinking about alternatives for storage/audit/retrieval.

Just keep in mind that the only "legal" data exchange format between
covered
entities for HIPAA transactions is according to the X12 specifications
embodied in the HIPAA guides adopted by the Department of Health and
Human
Services. No other exchange format, including XML, is allowed under
HIPAA.
So the issue of transaction volume bloat is a non-issue as far as HIPAA
transactions go.

Subject: RE: [EDI-L] X12 vs: XML File Sizes
Our experience in writing XML standards for a group of transactions,
using
the most efficient XML techniques, is that a document grows by a factor
of
10. This can be reduced a bit if you forego all visual formatting of
the
raw document and rely exclusively on screen/print templates for visual
presentation. However, at some point, it will be necessary to debug
document contents in raw form so this isn't a practical approach and it
creates documents that can be as arcane to read as X12.
If you are in any way bandwidth bound XML will be a major headache. If
you
have the bandwidth and don't already have a large investment in X12 it
will
be a faster implementation than trying to do X12. Converting from X12
to
XML is not easily cost justified. It usually happens for the same
reason
most people got into EDI in the first place; customer or regulatory
requirements.

I know I've seen some posts in this forum, on this (way back), but am
looking for any real-world metrics now that we have more experience in
the
XML sub-genre.
I'm looking for information about how much, on average, a typical X12
file
grows when converted to XML. Specifically, for the HIPAA
implementations of
X12 transactions.
I'm hearing unqualified reports of 80% bloat which is a far cry from the
3000 percent growth I seem to recall from the previous discussions.
I think those earlier figures were based on ordered pair
implementations.
Any information would be greatly appreciated.
If you could qualify the information with which XML
implementation/schema/DTD is involved, that would be helpful.
