The focus of the DIG35 Initiative Group is on defining metadata standards .
By establishing standards, the Initiative Group seeks to overcome a variety of challenges that have arisen as the sheer volume of digital
images being used has increased. Among these are efficiently archiving, indexing, cataloguing, reviewing, and retrieving individual images,
whenever and wherever needed.
Formed in April of 1999, the vision of the DIG35 Initiative Group is to "provide a standardized mechanism which allows end-users to see digital
image use as being equally as easy, as convenient and as flexible as the traditional photographic methods while enabling additional benefits
that are possible only with a digital format."
The main categories in which metadata elements can be classified are listed below:
- Image Creation metadata: camera capture, scanner capture, image source, creator, capture settings, scanner capture, captured item.
- Content Description metadata: caption, capture time, location, person, thing, organization, event, audio, dictionary reference.
- Metadata History metadata: processing summary, processing hints (cropped, transformed, retouched).
- Intellectual Property Rights metadata: Names, description, dates, exploitation, identification, contact point, history.
