ART Scenario Introduction

Introduction

Scenarios are a container for transaction groups and transactions and will typically represent a health care use case, e.g. a Medication Prescription or a Radiology Examination. With that, scenarios/transaction provide the usage context as starting communicating without knowing why is not suitable.

Transaction groups contain Transactions. There are two categories of transactions.

Category 1: The pair of "initial" and "back" used in the messaging paradigm where an initial information transfer evokes a response message in terms of an acknowledgement or in a query/response environment. This transaction typically has a sender and a receiver interacting.

Category 2: The "stationary" transaction that is a self-referencing transaction for example to create a document. This interaction typically has a "sender" only, that is more a creator of the document. Sending and receiving aspects are not part of this category of transaction and handled separately.

Transactions represent a (sub)set of concepts from a dataset and add cardinality, conformance and possible conditions to them so they reflect the use case demands appropriately. A transaction typically has a reference to a representing template, that is the technical representation of the transaction and its underlying concepts.
