Abstract
We showcase an approach to use workflows for composing applications from components with Linked Data interfaces. Our approach consists in an ontology and corresponding operational semantics. We use the ontology to describe workflow models and workflow instances in Linked Data. To execute workflows, we developed operational semantics for the ontology using ASM4LD, a rule-based language for specifying computation in the context of Read-Write Linked Data. For our interactive showcase, we use as components: (1) networked devices with sensors and actuators from the Internet of Things / Web of Things, and (2) APIs from the Web that produce and consume RDF.

Screencast about the demo
In the video below, we give an introduction to our demo by giving technical details and presenting a walk-through.
The workflow model
Our demo system is running a workflow model. We provide a Turtle representation of the workflow model, and a visual representation, see below.
