Topic: Purpose of bundle.link?
Tim Berezny (Oct 22 2018 at 17:52):
What is the purpose of bundle.link? I'm trying to figure out if it's relevant to my implementation project or not, but I don't really understand what it's trying to do.

It's primarily used with queries - self link, next, previous, etc. To my knowledge, we haven't given concrete guidance on its use in other circumances. How were you thinking of using it?
Tim Berezny (Oct 22 2018 at 18:02):
We're doing search on Appointments, GET {{baseURL_FHIR}}/Appointment/?_id={{servicerequest_ID1}}
And HAPI is inserting:
"type": "searchset",
"total": 1,
"link": [
{
"relation": "self",
"url": "{{baseURL_FHIR}}/Appointment/?_id=7791916917"
}
],
So, i guess in this case when the relation is "self" it just means, the value that comes after the GET statement? Is that the correct interpretation?
If that's where next and previous go for pagination , I can see that indeed being very useful.

Self echoes back the query that was actually executed - which may differ from what was submitted

more generally, it extends HATEOS into bundles, when that is appropriate.

This may help to get better understanding of link:
