What is digital indexing?

“Digital Indexing” is shorthand we often use to describe our work in audio/video content management for oral history. Digital Indexing encompasses the processes and various software tools we employ to annotate and index a/v recordings electronically. Although we have no formal definition for digital indexing, the Illinois State Museum described it for their Audio-Video Barn site during our partnership under an IMLS leadership grant in 2009-2010:

“Digital Indexing is a method of defining starting and ending points to an audio or video and then describing that portion of media in a set of notes that can be searched through keywords and control words. The results of this method are a set of searchable notes and the ability to instantly watch the exact corresponding portion of audio and video.”

Our work with “keywords and control words” will be the subject of a later post about “Multi-Dimensional Indexing”, which is our unique approach to controlled vocabulary in electronic environments. Future posts here will share some methods for summary-based annotation (typically applied before or in lieu of transcription) and an overview of The Interclipper™ software, a database system we find ideal for the challenge of recorded audio-video content management.
