2. Context-Free Callability

CONTEXT

• APIs have callable methods.
• Objects defined in OOP languages have callable interfaces (from methods).

DEFINITION

• Data is callable context-free, if it carries the web location of the origin of its instances, definition of schema (metaheader) to manage them, and optionally authorization data with permissions bound to machine’s identity (ssh public key).

TEST CONDITIONS

• Given a data record, can we call update operations or some method call without manually instantiating a client, or manually connecting with API.
• Does reading the data record within REPL of a language instantiate a fully-featured object, with address pointing to the data source, and methods allowing to interact with the source?
