## Post #1 by @thomas.beale

In a similar vein to the [post on citations in BMI](https://discourse.openehr.org/t/citations-and-references-bmi-example/3117), here is another example - Care Plan. Please refer to the BMI post for the general question. Here I will just post a graphic showing what I take to be the kind of thing @joostholslag and other clinical modellers want to do to represent a Care Plan. (Don't worry too much about whether my Care Plan design is right or not, just meant to be illustrative).

![care_plan|400x500](upload://kdZDj47pdp5VRHlEqb5qQnBQgj8.png)

In this diagram, the hollow boxes are 'virtual' Entries (using @ian.mcnicoll 's terminology), either EVALUATION (green) or INSTRUCTION (red), that point to 'real' Entries elsewhere in the same EHR.

Most likely, the reference in each case needs to indicate:
* the direct target, which is a whole EVALUATION or INSTRUCTION, and
* the parent.

Someone archetyping this reference would probably therefore want to constrain:
* the reference to be a certain archetype/RM type, e.g. `EVALUATION.problem_diagnosis`
* a parent object to be a certain archetype/RM type e.g. `COMPOSITION.problem_list`.

The meaning of such a constraint would be: this link at run time can only point to a problem/diagnosis EVALUATION, within a problem list COMPOSITION.
