all I was wondering if anyone had a full BNF for HL7 2.5? I am looking to compile this using the gold parser engine but would be happy to convert from EBNF or vendor specific BNF.

  • Have you tried looking around at HL7.org? – TheDevOpsGuru Sep 02 '10 at 13:54
  • HL7 standards docs (from HL7.org) inlcude a very limited BNF description of messages. I need a full lalr(1) compliant grammar that describes HL7. Is HL7 LALR(1) compliant? – jonathan Sep 02 '10 at 17:46
  • I'm sorry, I'm not familiar with what LALR stands for and Google is no help with the acronym, will you please educate me? – TheDevOpsGuru Sep 07 '10 at 14:39
  • I found what LALR means. I don't see anything that says HL7 is LALR compliant. Sorry for the lack of help, you may be the first person looking for this information. – TheDevOpsGuru Sep 07 '10 at 14:48

The BNF description of HL7 message can be downloaded here.

The documentation is pretty sparse and hard to get if you are not a member of HL7. The documents that you get once you sign up (and pay) are pdfs and the grammar is not easily ingested.

There are discounts for your affiliation with differing organizations. For instance, they will call the AMA to check your credentials if you claim to be a provider.

We have had to slow our HL7 rollout and implement only the messages as we need them, as opposed to simply having a parser chew out the schema. It is clear that HL7 was made in a more 'golden' age of the Internet.

After a few days of researching (which I am sure you have tried) I cannot find a BNF for HL7 v2.5. I would recommend that you try to joing the HL7 community at www.hl7.org and see if you can push some buttons to get a more descriptive BNF designed. Good luck.
