Object Selection Documents can be thought of as Structured Reports without the report!

Whilst this might sound stupid, it makes sense as they are used merely as a “manifest with a purpose”, sharing most of the attributes of Structured Reports.

There are multiple names by which this object type is commonly known:

• Key Image note (KIN)
• Key Object note (KON)
• KOS

They can be used for multiple purposes where it is required to “group” or “sub-smaple” Composite Instances, such as

• Images for quality control
• Teaching
• Access over slow connections
• They are also used in the IHE XDS-I profile
• As a means of identifying images to be deleted for Image Object Change Management
