Question: ISO 21090 Schema

Oct 1, 2012

Question

The ISO 21090 PDF has a link to the HL7 website where the schema can be obtained:http://www.hl7.org/implement/standards/iso_datatypes.cfm. There are schema errors in the schema available at this link (the invariant rules reference HXIT members that have been renamed).

This was fixed on the editors’ resources website but HL7 now has the wrong version…

Also, in your HL7 video you said you moved the schematron rules to a separate file. This isn’t so.  Is there another schema where the rules have been taken out?

Answer

I have asked the HL7 webmaster to update the link above to the latest version. In the meantime, it’s available here. I did create a separate schematron file, but it hasn’t made it’s way onto the implementer’s resources page… probably my fault. You can get it here. There is no equivalent schema with no schematrons in it, though preparing it is not difficult (just a little time-consuming).
