HL7 v3 (XML) importer

Discussion in 'Python' started by Luke Kenneth Casson Leighton, Aug 6, 2010.

  1. an HL7 v2 importer was written by john paulett, and it has been
    enhanced to support some of the HL7 v3 standard, which is XML-based.
    no dependencies are required: xml.sax is used so as to reduce the
    dependencies to purely python.

    additionally, as HL7 has versions/revisions, published data
    specifications were pulled from mirthcorp.com and transformed into
    python, automatically. HL7v3 revisions 2.1, 2.2, 2.3, 2.31, 2.4 and
    2.5 are supported.

    there is still work to be carried out: MSH, PID, NTE, ORC, ORB and OBX
    are the presently supported segmentss, with a hard-coded assumption
    about the data hierarchy instead of using the same MessageFormat
    specifications that mirthcorp.com have written. this is likely to be
    corrected soon, but the project for which the code is being updated
    only requires "lab data imports", so support for other MessageFormats
    is not a high priority.

    in case anyone is interested, this hl7 library is to be used in
    gnumed, to be able to import laboratory data reports into the gnumed
    database.

    code is at: http://github.com/lkcl/hl7

    i realise that this code is pretty specialist, but if you're looking
    around for free software libraries or applications that support HL7,
    http://mirthcorp.com is pretty much it, and mirth is pretty heavy-duty
    and forces a dependency of java and javascript for scripting, which
    may be of concern to some. hence, this smaller library is being
    created, in python.
