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.
