NOTES

Health Care Use Case

Let's discuss the use of XDI messages and link contracts for a use case of a patient/doctor/hospital interaction scenario that Markus has been working on.

Markus described a health care use case involving a patient and a doctor as follows:

• Patient starts with a set of medical records.

• Patient consults a Doctor (no pre-existing relationship).

• Doctor sends patient an XDI request for:

• Reading the patient's current medical records.

• Asking permission to write additional medical records.

• Patient agrees to the request (some variations possible at this point).

• Doctor reads Patient's medical records.

• After consultation, doctor writes a new medical record to Patient.

We considered the following pattern to express medical records:

     =!:did:sov:1111#medical[#record]*!:uuid:1234<#pulse>/&/".."

     =!:did:sov:1111#medical[#record]*!:uuid:1234<#weight>/&/".."

     =!:did:sov:1111#medical[#record]*!:uuid:5132<#pulse>/&/".."

     =!:did:sov:1111#medical[#record]*!:uuid:5132<#weight>/&/".."

We discussed the difference between the following XDI operations:

    Simply requesting an XDI subgraph:

    =doctor[$msg]@~1$do/$get/=!:did:sov:1111#medical[#record]

    Request using an XDI variable:

    (=doctor[$msg]@~1$do/$get){}/$is#/#medical#record

We ended the call after 30 minutes, but agreed it will be valuable to work through all steps of this scenario in more detail.
