Processing digitization output¶
During a digitization project, it is common to create a master digital object (such as a high-resolution TIFF) as well as an access or service copy of the object (such as a lower-resolution JPG). Archivematica can recognize the relationship between the master and access or service versions of the object and use them to generate a DIP.
Generating a DIP using access derivatives¶
- Place the master digital objects in the transfer directory.
- In the top level of the transfer directory, create a subdirectory called access (no capitalization).
- Place the access copies in the access directory. The master and access copies must have the same filename, although the extensions can be different - for example, image-1.tif (master) and image-1.jpg (access).
- Process the transfer.
- At the normalization microservice, choose « Do not normalize ».
- Archivematica will keep the master digital objects in the AIP and generate a DIP from the copies in the access directory.
Generating a DIP using service files¶
- Place the master digital objects in the transfer directory.
- Create a subdirectory called service (no capitalization). Place the service copies in this subdirectory. The master and service copies must have the same filename, although the extensions can be different - for example, image-1.tif (master) and image-1.jpg (service).
- If there is an access directory created as per the instructions above, process the transfer as before, choosing « Do not normalize » at the normalization microservice. Archivematica will generate a DIP from the objects in the access directory.
- If there are no access derivatives, choose « Normalize service files for access » at the normalization microservice. Archivematica will use the service copies as the basis for generating the access derivatives, instead of the master objects.
- The service copies will be retained along with the master digitized objects in the AIP and Archivematica will capture their derivation relationships in the AIP METS file.
