You can add additional data from other sources like tumor registry, pathology databases, or other clinical databases into OpenSpecimen. This data will be available in the OpenSpecimen query interface and catalogs.

There are two ways of doing this:

1. Via custom forms and bulk upload
2. Via direct database inserts

Via Custom forms and bulk upload

1. Create a custom form via form builder that contains the fields you want to include.
2. Hook with the participant, specimen or visit, and one or more collection protocols.
3. Go to "Import" in the "Collection protocols" list
4. Download the BO template for the new custom form.
5. Use the BO CSV file to import data into OpenSpecimen.
6. Learn more about bulk import here: Bulk Operations (CSV Import)

Via direct database inserts

Steps:

1. Create a new table in OpenSpecimen with the necessary data
2. The new table should have a foreign-key to either participant, visit or specimen table.
3. Open the respective XML from the below folder
4. Edit the XML to include all the columns in the table
5. Refer to the existing XMLs to get an idea for the synxtax for different datatypes.
