- TYPE, “Type of object”. ly = Lydfil, ol = Omslag lille (width 120), os = Omslag stor (height 450), org = original omslag (This is the original image file sent to Bokbasen, so this is the one with the highest quality. This only exists for files sent to Bokbasen after February 2015, for older files this will be the same quality as os)
- REFERENCE - short lived link to object available for download at download service. Reference is generated in a dynamic non predictable manner.
- Note that this database also contains historical objects, so that you can get objects for books that are deleted and sold out, so one should always check if the object is required for your system in your import process
- The database is containing objects for over 150 000 titles, so a full dump on the database is very time consuming. When doing this, the biggest impact is choosing which types you actually need so you do not incur unecessary requests. E.g. if you are only loading images and you only need ORG, that will require about 150 000 download requests, but if you include all types for images that becomes 450 000 requests and trippling your execution time.
Object Download Service
The Object Download Service provides an endpoint for downloading binary object resources. The path to this service, as well as a unique identifier of the requested object, is returned from the object metadata service, which therefore must be called in advance. The unique identifier is only valid for a certain amount of time, as described in the table below, and can only be called by the same user (credentials) that requested the object export metadata service. The following details the parameters, example usage and different responses when using this service.
