Harald Rohlig Audio

Digital Collection identifier: u0008_0000002

Summary The Harold Rohlig Organ Music Collection contains performance recordings of organist Dr. Harald Rohlig, retired Professor of Music at Huntingdon College, Montgomery, Alabama. Most recordings in the collection were made at Memorial Presbyterian Church, Huntingdon College, or St. John's Episcopal Church in Montgomery, Alabama. Recordings are on reel-to-reel tape and digitized to archival .wav format by Digital Services. Mary Alice Fields has been listening to the performances and recording descriptive and structural metadata. Performances are tracked out and access .mp3 files are created and uploaded by Digital Services for each track. Further information about the Harold Rohlig Collection is available in the | finding aid.

Scope Approximately 250 reels of audio comprised of about 250 program (performance) items are currently included in the project scope. There are an additional ~15 reels, ~718 cassettes, ~3 minidiscs, and 1 CD in the physical collection that are not yet digitized.

Special Metadata Considerations MODS records are created with the program (performance) at the item-level. Works (also includes program announcements, interludes, etc.) within the program are nested within the item record as constituent related items (<relatedItem type="constituent">) Any intellectual subdivisions within each work are nested as constituent related items within the respective work. mp3 files (tracks) correspond to the narrowest subdivision within each work. Durations of each track are represented in the <extent> field of each track's respective <relatedItem> element. The duration of each work (recorded in the work's <extent> field) is the sum of the durations of the work's constituent items.

Workflow Workflow on the Metadata Unit side goes as follows:

  • MU receives completed spreadsheets from Digital Services (who had received the spreadsheets from Mary Alice and created preliminary audio files and records).
  • MU remediates Mary Alice's metadata in the spreadsheet.
  • MU generates MODS from the spreadsheet in Archivist Utility (using template M02), then runs the Python/XSLT scripts ( on these records to create item-level MODS with nested constituent items. (rawMODStoMODS.xslt will be incorporated into this process.)
  • MU uploads remediated metadata to live server.
