5. FHIR in a Nutshell FHIR is like Lego(™) for Healthcare
Resources = Blocks
Resources are discrete chunks of clinical information
Resources can be assembled into larger constructs
You operate on resources via FHIR’s REST APIs.
Think Programming Lego Mindstorms (™)

6. Templating/Profiling Tasks (80/20 rule)
Changing Cardinality
Make optional things required
Limit repeatable or optional things to 0 or 1
Constraining References
Require Reference types to match a specific profile
Slicing/Branching
Predicate logic like a SQL WHERE clause.
Appears as “such that” constraints in CDA implementation guides and slices in FHIR profiles.

7. Creating an Implemention Guide
Structure of an Implementation Guide
Create the building blocks (templates/profiles) and then relate (link) them to one another to create an Implementation Guide
Code systems, value sets and values are bound to elements and attributes in a template/profile
