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.
