info Use of the RELMA Database


The RELMA program uses a database that includes the LOINC table and other database tables. As indicated in the terms of use, users may use the LOINC table by itself, but not use the other database tables from the RELMA database (except in conjunction with their use of the RELMA program) without prior written permission from Regenstrief Institute, Inc. The other tables in the RELMA database are in constant flux to support changes to the program, and we are not able to support migrations. We are aiming to provide exports of key content in a published format, such as the panels and forms file and other LOINC accessory files.
