Description
Currently DICOM specifies how to encode references to Bulk Data in the JSON and in the
XML representaion of Data Sets, but does not specifies how to encode references to Bulk Data
in the binary encoding. I suggest to encode them in items of a new defined Sequence Attribute:
Attribute
Name
Referenced
Bulk Data
Sequence
>Selector
Attribute
>Selector
Attribute VR
>Selector
Sequence
Pointer
Tag
Type
(FFF8,FFF8) 3
A sequence of Items where each Item reference a blob of
data that the recipient may retrieve through WADO-RS.
(0072,0026) 1
Data Element Tag of the referenced bulk data.

Attribute Description
(0074,1057) 1C
The Value Representation of Selector Attribute
(0072,0026).
Contains the Data Element Tags of the path to the
Sequence that contains the Attribute that is identified by
Selector Attribute (0072,0026). This attribute shall have
the same number of values as the level of nesting of
Selector Attribute (0072,0026). Required if Selector
Attribute (0072,0026) is nested in one or more Sequences.
Identification of the creator of a group of private data
elements used to encode attributes in the Selector
Sequence Pointer (0072,0052). This attribute shall have
the same number of values as the level of nesting of
Selector Attribute (0072,0026). For values of the Selector
Sequence Pointer (0072,0052) that are not the Data
Element Tag of a Private Attribute, the corresponding
value in Selector Sequence Pointer Private Creator
(0072,0054) shall be empty. Required if Selector Sequence
Pointer (0072,0052) is present and one or more of the
values of Selector Sequence Pointer (0072,0052) is the
Data Element
Tag of a Private Attribute.
Identification of the Item indices in the Selector Sequence
Pointer (0072,0052). This attribute shall have the same
number of items as the level of nesting of Selector
>Selector
Attribute
(0072,0056) 1C
Private Creator
>Retrieve URL (0008,1190) 1
Attribute (0072,0026). Required if Selector Sequence
Pointer (0072,0052) is present.
Identification of the creator of a group of private data
elements. Required if the Selector Attribute (0072,0026)
value is the Data Element Tag of a Private Attribute.
URI/URL specifying the location of the referenced bulk
data
