Sequence perspectives show detailed interactions between resources. Sequence perspectives are perfect for showing actions between resources that happen in a sequential order. While flow and ring perspectives are great for showing static relations between resources, sequence diagrams are ideal for showing what resources do.
To create a flow perspective, simply declare a sequence in your perspective using the sequence property.
Defining the sequence
In IDL, a sequence is defined like so:
# Resource tree omitted ... perspectives: - name: Get Diagram color: LimeGreen sequence: start: Users steps: - to: ns label: Get diagram - to: iloUsers label: Authenticate user - to: ns - to: getIlograph label: Invoke - to: Ilographs label: Get metadata - to: getIlograph - to: Permissions label: Get permission - to: getIlograph - to: diagrams.ilograph.com label: Retrieve content - to: getIlograph - to: ns label: Return diagram - to: Users label: Return diagram ...
When rendered, this perspective might look like the above image.
Arrow labels and descriptions
The arrows can be labeled and given descriptions using the label and description properties on each step. Just like with flow perspectives, the label appears above the arrow, while the description appears on mouse-over.
