OtherMaterial

Non-data file properties map to DDI OtherMaterial elements according to the table below.

Note

In DDI, the OtherMaterial type does not support UserAttributes. Therefore, to store information not built in to the OtherMaterial type, this mapping uses the UserID as a key-value store. This is not semantically ideal, but is an interim solution until a future version of DDI supports saving extended information about OtherMaterial items.
