Hi Masoud,
I am not an xml expert, so take this with a grain of salt.
I think that something is wrong/unmatched with the first line of your xml
document.
Make sure that the first line is something like:
<?xml version="1.0" encoding="utf-8"?>

* External Email - Caution *
Hi all,
I'm using cTAKES user to process CDA documents by AggregateCdaProcessor.xml and
AggregateCdaUMLSProcessor.xml located in
/desc/ctakes-clinical-pipeline/desc/analysis_engine/
My script to call this is
java -Dctakes.umlsuser= -Dctakes.umlspw= -cp
$CTAKES_HOME/lib/*:$CTAKES_HOME/desc/:$CTAKES_HOME/resources/
-Dlog4j.configuration=file:$CTAKES_HOME/config/log4j.xml -Xms2g -Xmx3g
org.apache.ctakes.core.cpe.CmdLineCpeRunner
$CTAKES_HOME/desc/ctakes-clinical-pipeline/desc/collection_processing_engine/test_cda_masoud.xml
test_cda_masoud.xml has a proper path to CDA input and output. I'm using the
two CDA files that come with the cTAKES package (testpatient_cn_2.xml and
testpatient_cn_1.xml compatible with NotesIIST_RTF.DTD).
Unfortunately, it seems that CdaCasInitializer cannot run, and I get the
attached errors. I get the same errors when using the GUI with
AggregateCdaProcessor AE
- Am I missing something obvious?
- Does cTAKES *User* installation handle CDA documents?
- Is org.apache.ctakes.core.cpe.CmdLineCpeRunner an appropriate pipeline for
CdaCasInitializer?
Thank you so much for your help in advance.

Hi Masoud,
I think that the CdaCasInitializer is at least 10 years old. I would not
expect it to conform to any recent standards.
Does anybody else have a reader or transformer that can handle HL7 CDA r2?

p.s.
If anybody is involved with HL7 International, you may want to get some
movement on addressing the typo on the page header(s):
Section 1a: Clinical Document Architcture (CDA®)

Dear cTAKES developer mailing list,
We have been working on a project at Hopkins for converting Epic-generated
RTF notes into Clinical Document Architecture Level One.
We have been using HL7 CDA® Release 2 Schema, and now we plan to use cTAKES
for concept extraction from those documents. The CDA Schema and examples can be
found here
https://urldefense.proofpoint.com/v2/url?u=https-3A__www.hl7.org_implement_standards_product-5Fbrief.cfm-3Fproduct-5Fid-3D7&d=DwIGaQ&c=qS4goWBT7poplM69zy_3xhKwEW14JZMSdioCoppxeFU&r=fs67GvlGZstTpyIisCYNYmQCP6r0bcpKGd4f7d4gTao&m=h8q4BiKKL6eDBOGEta7gcpkDGIx5xFPlGrNfUPlzBuc&s=l8HjgDHeywmdkSUkOJBGWNLpJ-bPlw7Lmgzh02w8k2s&e=
In the cTAKES documentation, I see that CdaCasInitializer "does not handle
all CDA documents. The CDA document must conform to the DTD
resources/cda/NotesIIST_RTF.DTD."
Has anyone tested and evaluated cTAKES ability to consume HL7 CDA Level 1
Release 2 documents?
Thank you,
Masoud
