These are the datamodels and metadata formats used in DOMS.

Radio and TV

The Radio/TV collection is the most complex in structure of all our collections. This is mainly due to three aspects:

In order to create an accurate description of a single program, we combine metadata records from two external providers of program metadata, Ritzau and TV-Meter, into one PBCore record. This record is the main descriptive record for the program. If errors are detected, the PBCore record can be manually edited .

A number of tools are run on the files, e.g. FFprobe and Crosscheck, and the output from these is also stored in the Existing Metadata Repository and linked to the file.

So for the Radio/TV collection the Existing Metadata Repository holds these types of records:

The commercials collection contain both television commercials and commercials from movie theaters. The datamodel is fairly simple, with one PBCore metadata record per file.





In the newspaper collection (digitised printed newspapers) we use ALTO, MIX, MODS (3 different profiles) and PREMIS. In addition we use custom schemas for characterisation information of image files, administrative data for discovery and for describing newspaper microfilm reels (administrative and technical data).

Our newspaper collection is hierarchically structured on a logical level with data on the newspaper title (MODS), on the issues (MODS) and pages (MODS, MIX, ALTO and ACCESS data) . Furthermore we have characterisation information from Jpylyzer for our JPEG2000 image files.

The complete metadata for the newspaper digitisation workflow extends the model and is based on microfilm batches, each consisting of a number of microfilm reels containing issues as described above as well as extra images with test targets and a number of extra pages.
