Restricted datastreams
The following datastreams serve pre-defined functions in the DAMS and are managed by the system. If you want to add a custom datastream do not use one of these IDs, otherwise the system might overwrite custom data.
System Generated
DAMS automatically generates this datastream. If you upload your own file attached to this datastream it may get overwritten. Example: In the case of OCR if you upload your OCR to that datastream and then someone runs the generate OCR on the item your will be overwritten.
User Provided
You can provide your own datastreams, if you provide a datastream with one of the restricted datastreams expecting to be user provided the system may have special behaviors. Example: In the case of a user provided PDF it will have preference in the system to be displayed.
