Oral History Metadata Synchronizer

The Oral History Metadata Synchronizer (OHMS) is a web application designed to enhance online access to oral history interviews. OHMS was originally designed and created by the Louie B. Nunn Center for Oral History, University of Kentucky Libraries in 2008 for deployment through the Kentucky Digital Library. In 2011, the Louie B. Nunn Center for Oral History received a grant from the Institute for Museum and Library Services to make the system open source and free to use with interoperability and sustainability as the primary goals. According to the Nunn Center, "The primary purpose for OHMS is to empower users to more effectively and efficiently discover information in an oral history interview online by connecting the user from a search result to the corresponding moment in an interview."

OHMS is a two-part system which includes the web app (the back-end) and the viewer (user interface). The web application is used to prepare the oral history interview by embedding timecode into a transcript or creating a time-coded index of the interview, which is then viewable online in the OHMS Viewer, accessible form the archive's chosen content management system.

The original version of OHMS synchronized transcribed text with time code in the audio/video, as well as providing a user map/viewer that connected search results of a transcript to the corresponding moments in the audio or video.OHMS designer Doug Boyd writes "OHMS inexpensively and efficiently encodes transcripts of interviews and then connects the transcripts to the corresponding moments in the audio or video interview. ".

In 2011, the Nunn Center introduced the Interview Indexing Module which allows indexing or annotation of an interview that corresponds to time-code. In his article in the Chronicle of Higher Education, Brad Wolverton writes about Doug Boyd's work on OHMS: "Through his work as director of the Louie B. Nunn Center for Oral History he’s developed a method for indexing audio and video recordings, making it easy for researchers to call up precise words without having to listen to endless hours of tape." In the Fall of 2011, the Institute for Museum and Library Services awarded the Nunn Center a National Leadership Grant of$195,853 to further develop OHMS for open source distribution. OHMS is currently being developed and the grant initiative is working with project partners to implement the system beyond the University of Kentucky.
