If you are familiar with XML file structure, you can determine OIDs using the Study metadata file:

  1. Download the Study metadata file: Select Tasks > View Study, then follow the instructions at the top of the page.
  2. Open the Study metadata file in a browser or text editor.

Following is an excerpt of a Study metadata file that provides an example of the structure, showing only the tags that are relevant to finding and determining OIDs needed for the data import file. Comments <!– … –> indicate where the OID values are. You can download and view the complete Study metadata file for the example Study.

Starting with the <Protocol> tag, the general structure is that the OID for an element is defined in a <…Ref> tag. After that, a <…Def> tag for the element contains tags that define the OIDs for the subelements, and so on, through the hierarchy. The heirarchy is: Study Event Definition > Form (CRF) > Item Group > Item.
