Research reference: Xanadu and information references

[xiaoland]

The original reference is impl-py#16: Xanadu, which links to xanadu.com. This discussion is a place to explore potentially useful connections to information references, provenance, and reading in InKCre.

Please start from a concrete use case: which information relationship should be preserved or shown, what current behavior falls short, and how would an improvement be observed? Once the problem and acceptance are clear, open an implementation issue in its owning repository.

The original issue retains its source and history. No new product commitment or implementation task has been accepted from the reference alone.
