Something I am struggling to understand is the concept of local annotations to OData service metadata in UI5 apps (specifically for OData v4, I think…).
I have managed to do little things like make an input multi-line, or hide and element, by using examples gleaned from here or there, but I cannot find any comprehensive reference on annotations, and especially a good guide that explains the basic concepts, and how annotations are structured (For example, when and how do you use Collection and Record and Propertypath elements, etc).
There are little bits of documentations and blogs that show how to do one thing all over the place, so it’s really a lot of trial and error (and mostly error!) and little to no success.
If anyone knows of a comprehensive body of documentation that covers this topic, please share!
