'easy' way to insert references to previous elements?

[Nick]

How can I insert a reference (e.g. 1.2.3.4) to an earlier element, without specifying the whole 'path' to the element? Can I query DcmItem's for their path? Quite error prone to type those myself, heh.

Thanks in advance,

What do you mean by that: "insert a reference (e.g. 1.2.3.4) to an earlier element"? Are you talking about DICOM SR documents?

[Nick]

Aren't they used anywhere else? But yes, it's for SRs .

[J. Riesmeier]

No, these kind of "internal references" are only used for the SR document tree, and for these kind of DICOM objects you should definitely use the "dcmsr" module with its higher-level API. Then your question boils down to simply use DSRDocumentTree::addByReferenceRelationship() with the node ID of the referenced content item. The node ID is what addContentItem() and other methods of this class library return

Hmm, okay, thanks a bunch.
