Hello, I have examined the list of databases that have already been converted to CDM v. 4 in http://www.ohdsi.org/web/wiki/doku.php?id=resources:data_network. The one I am interested in is shown there as having been converted. However, I don’t see any link that would allow me to download it. Any suggestions? Thanks much.
Hi, Which dataset is it? Usually, because of data use and Human Subjects
restrictions, the only thing that can be downloaded is the ETL
documentation. However, the OHDSI is a research network, so if you have
ideas that you would like to investigate on a specific dataset, there is
the possibility of that to happen as a collaborative. -Rich
OK, thanks, that makes sense. It was the JMDC data. I have downloaded the ETL specification document created by , and have been able to create my own programs from it. I guess that’s good for now. Thanks again. 
Ooops, meant to say the ETL specification by Schumie and Matcho, June 2015.
