As per Latest Reference-ccda-validator code base,  <artifactId>org.eclipse.mdht.emf.runtime</artifactId>   version is 3.0.0-SNAPSHOT.   https://github.com/onc-healthit/reference-ccda-validator/blob/master/pom.xml#L80
<dependency>
<groupId>org.eclipse.mdht</groupId>
<artifactId>org.eclipse.mdht.emf.runtime</artifactId>
<version>3.0.0-SNAPSHOT</version>
</dependency>

But As per this Artifactory (http://34.195.107.72:8081/ui/native/libs-release/mdht/eclipse/mdht/org.eclipse.mdht.emf.runtime/) version is  3.0.0.202408220500/.

Hi Atanu 

We have a internal build process that does leverage some maven dependencies for the MDHT

The general question I have is - what are you attempting to do with MDHT ?  Are you looking to have a stand alone application that uses MDHT

The current deployment of the validator does bundle the latest and greatest MDHT version 

Thanks

Sean

Hi Team,

I am using the Reference CCDA Validator to validate a C-CDA document. I noticed that the validation results differ between the Reference CCDA Validator and the C-CDA Validator hosted at
https://site.healthit.gov/c-cda/uscdi-v1, which appears to be due to differences in the MDHT library version.

Could you please let me know which version of the MDHT library is currently being used by the C-CDA Validator hosted at https://site.healthit.gov/c-cda/uscdi-v1?

Regards,
Atanu

Hi Team,

When running the Reference C-CDA Validator with version 3.0.0.202408220500 of the org.eclipse.mdht.uml.cda library, we receive 7 Conformance Errors. However, when using version 3.0.0-SNAPSHOT, the validator reports only 3 Conformance Errors. The C-CDA Validator hosted at https://site.healthit.gov/c-cda/uscdi-v1 also reports 3 Conformance Errors.

The additional 4 Conformance Errors reported by version 3.0.0.202408220500 are all the same:

"Consol Policy Activity (V3) SHALL contain exactly one [1..1] code, which SHOULD be selected from ValueSet Health Insurance Type 2.16.840.1.113883.3.88.12.3221.5.2 DYNAMIC (CONF:1198-8903). code SHALL contain at least one [1..*] translation, which SHOULD be selected from ValueSet Payer 2.16.840.1.114222.4.11.3591 STATIC (CONF:1198-32852)."

This error appears four times, accounting for the difference in the total Conformance Error count.

Could you please let us know which version of the org.eclipse.mdht.uml.cda library is being used by the C-CDA Validator hosted at https://site.healthit.gov/c-cda/uscdi-v1?


Regards,
Atanu

Please look at the pom.xml to find the exact library being used.

Hi,

As per the latest reference-ccda-validator pom.xml, the org.eclipse.mdht.emf.runtime dependency is configured with version 3.0.0-SNAPSHOT:
https://github.com/onc-healthit/reference-ccda-validator/blob/master/pom.xml#L80

<dependency> <groupId>org.eclipse.mdht</groupId> <artifactId>org.eclipse.mdht.emf.runtime</artifactId> <version>3.0.0-SNAPSHOT</version> </dependency>

However, according to the MDHT Artifactory, the latest available release version is 3.0.0.202408220500:
http://34.195.107.72:8081/ui/native/libs-release/mdht/eclipse/mdht/org.eclipse.mdht.emf.runtime/

Could you please confirm which version of the MDHT library is currently being used by the C-CDA Validator running at https://site.healthit.gov/c-cda/uscdi-v1?

I am trying to understand the reason for the validation result differences between the Reference CCDA Validator and the hosted C-CDA Validator

Regards
Atanu.

Hi

The latest version of the MDHT is here 


The next release of the validator would use this version

There is not overall global  maven repository that supports all the dependencies which prevents us from having a reasonable artiifcatory 

Let me know if this make sense

thanks

Sean
