C.38.3.1 Inventory Creation Module Attribute Descriptions

C. Referenced SOP Instance UID

The content of an Inventory may be divided into more than one Inventory SOP Instance, organized as a tree of SOP Instances with one SOP Instance as the root (see Section C. and Section YYYY.3.3 “Inventory Instance Tree” in PS3.17). Only the root Inventory SOP Instance is identified in this data set in the Referenced SOP Instance UID (0008,1155); that SOP Instance includes the entire tree of references to SOP Instances comprising the Inventory.

C. File Access Uriand Stored Instance Base URI

If the produced Inventory SOP Instance is stored in the DICOM File Format (see Section 7 “DICOM File Format” in PS3.10) and is accessible through a non-DICOM protocol (see Annex P), the File Access URI (0008,0409) contains an [RFC3986] URI for non-DICOM protocol access to the Inventory SOP Instance. File Access URI (0008,0409) may be a relative path reference URI, which is merged with the Stored Instance Base URI (0008,0407) in accordance with Section P.2.1.

File Access URI (0008,0409) may reference a container file that includes the Inventory SOP Instance (see notes in Section C.

C. Expiration DateTime

A data management system may manage the storage lifecycle of the Inventory SOP Instances (e.g., by deleting older Inventory objects after a predetermined time). If there is a scheduled or expected time for SOP Inventory Instance deletion, it may be identified in the Expiration DateTime (0008,0416) Attribute. This is not a guaranteed expiration time; the SOP Instances may become unavailable at an earlier or later time. This Expiration DateTime (0008,0416) applies to all available access methods (both DICOM and non-DICOM protocols).
