Same-schema-integration of RetroGuide and i2b2

November 19, 2008

i2b2 is a biomedical informatics project around EHR and genomic data. (www.i2b2.org).

RG schema can be saved into i2b2 form.
The BLOB in observation table can be used to store XML data from columns of RG schema which i2b2 does not have.

The demo data do not provide examples of the BLOB structure.
