Altering the base profile

The first thing to do is to adjust the base elements in the profile. Because clinFHIR only supports a subset of the possible profiling options, this can be done by selecting the appropriate check box: 

• Req - short for Required. Check this box if a resource that is conformant to this profile Must have one of these elements in it. A required element will be coloured red.
• Mult - short for multiple. This means that a conformant resource may have more than one of these elements
• Incl - short for include. Unchecking this box means that the element is not supported in the profile. These elements will have a 'strike-through' through the path name.

Note that you cannot apply all options to all elements. FHIR has certain rules about profiling to ensure interoperability - for example an element in the base spec cannot be made optional in a profile. (This is one of the reasons why there are so few required elements in the base spec).

Note also that as you select & un-select the checkboxes the Cardinality will change - actually, that's all the checkboxes are doing.
