Each line of the Schedule File is a minified JSON object that conveys information about a Schedule to which slots are attached. The Schedule represents a particular healthcare service (e.g., primary care appointments, specialist consultations, or procedures) offered at a specific location or by a specific practitioner role.
Example Usage Scenarios
Schedules can reference multiple actors in the actor array to provide more specific context about the healthcare service. Common patterns include:
The following data elements must always be present or must be supported if the data is present in the sending system. They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Views below provides the formal summary, definitions, and terminology requirements.
Each Schedule Must Have:
