Hi i am getting this error when using OCC 2.01 and define v2.0. I have following statements in the define similar to CDISC example:

<ODM

xmlns="http://www.cdisc.org/ns/odm/v1.3"

xmlns:xlink="http://www.w3.org/1999/xlink"

xmlns:def="http://www.cdisc.org/ns/def/v2.0"

Thanks.

OD0002 error: Missing or invalid Namespace attribute

You might want to add the following on the ODM element:

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

However, this namespace declaration is only required if you also have:
xsi:schemaLocation="..."

As is well explained in the define.xml 2.0 specification on page 52, section 5.3.3.

I also encourage you to first validate your define.xml file against the XML-Schema. This should ALWAYS be the first validation step. If you do indeed really have a missing namespace declaration, schema validation will also tell you for which elements or attributes the namespace declaration is missing.

Hi, I don't have namespace

Hi, I don't have namespace xsi:schemaLocation="..." but for some reason i do not get this error anymore either. I am using style sheets and schema's provided in the define 2.0 example from CDISC. Do i still need to validate define against schema? if so how do i do that?

Thanks.

define.xml schema validation

Well, I cannot force you to ...

How XML-Schema validation for define.xml can be done is very well explained in the "XML Schema Validation White Paper" published by CDISC at: http://cdisc.org/define-xml . The white paper is still for define.xml 1.0 (we are currently working on a new version), but essentially everything still applies, except that you now need to validate against define2-0-0.xsd.

Not a bad idea to start learning principles of XML, namespaces and schema validation though. I teach it to my undergrade students in just 2x 1.5 hours...
