OHMS is not a repository. The OHMS Application is where you import your metadata and prepare it for access via the OHMS Viewer.  In order to make your interview public, you will export the OHMS XML file, place the OHMS XML File on the server where you have the OHMS Viewer installed, and link from your CMS to the corresponding  OHMS XML file. .  The digital audio or video files themselves must be hosted elsewhere and the OHMS system merely links to them in order to index the metadata.  In fact, The OHMS Application is designed to serve as a pass-through of your metadata and should be deleted when you have made your interview public.  The OHMS XML file can always be imported back into OHMS to make changes.
