In the HL7 Adapter, this schematron is useful for validating an HL7 V3 document against
predened schematron schemas that you write. You can also obtain schemas from
organizations such as NHS and HL7.org. For example, NHS provides schemas for CDA
documents.
Schematron Conguration in HL7 Adapter
You congure the schematron validation from the Connectivity Map Properties Editor. The
Properties Editor includes two properties to support schematron validation:
■
Schematron Validation: Selecting true enables schematron validation. You then need to
enter an LDAP reference.
■
Schematron Files: The list of schematron validation les. Use commas to separate multiple
les.
API for SchematronValidation
The HL7 Adapter includes an API specic to schematron validation. This API is a wrapper of
the Open source XSLT-based API available at
http://xml.ascc.net/schematron/1.5. The
API is an XSL le called metastylesheet (skeleton1-5.xsl ). Applying the metastylesheet to the
schematron XML document generates another XSL le. This XSL le can be applied to the
input XML document to validate, which produces the output XML document that contains the
results of the validation. This document can be embedded inside the V3 acknowledgement and
can be sent to the original sender.
The metastylesheet can be extended and overridden so that you can customize the output XML
document.
Example,
The following is an example of an output document generated after invoking the API using the
XML input document and the schematron validation document described above.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
