Editor's Notes
- #4: http://www.familyfuncalgary.com/wp-content/uploads/2012/12/Bricks-4-Kidz-Birthday2.jpg
- #6: Create flexible compositions that easily weave together interactions with known services and APIs, making use of a rich API catalog Define points of variability to expose your recipes to end users for customization and reuse Make your recipes available for reuse and have them ready to run in the Cloud Instantiate with own API entitlements and configuration
- #7: Lookup recipe. Configure the Recipe: Enable channel (configure API), provide parameter settings for the recipe. Run it.
- #8: Instantiate Recipe “Deploy to BlueMix” Show Deployed Application in BlueMix Txt 2 Home (OpenHab UI + Google Voice)
- #11: Switch to API catalog
- #12: Name API dependencies Configuration parameters BlueMix
- #14: Lookup recipe. Configure the Recipe: Enable channel (configure API), provide parameter settings for the recipe. Run it.
- #16: Talk also here about the language
- #17: Show dev experience and language. Show the same api come up from the home owner slide and the catalog screen grab. Will be in jazzhub. Explain splice and so on. If this is demo part: start with create a very simple interaction flow and then show the whole home one.
- #27: Pattern is a template of an App contains deployable assets, with configurable properties and bindings to service dependencies. Registered in pattern catalog. Service dependencies refer to services registered in service catalog. May or may not expose an API with endpoints. Must be configured before being deployed. Deployed to Cloud OE using the SSE fabric.
