11. What’s An Activity?
{user} {verb} {object} [{target}]
It is a Semantic and Ontology
Problem That Can (and Will)
Evolve Over Time
Good News: This Can Be Decoupled From The Underlying Code

12. What’s An Activity-based API?
- {verb} {object} [{target}]
+ Method (GET/POST...) Activity Opportunity
+ Contraints... (Cost, Duration...)
...
An API That Publishes High Level “Activity” Resources
