Golem Activity Capabilities

Namespace that describes Activity API capabilities, which can be perceived as “segments” of Activity API functionality.

Example segments can be:

• ways of transferring/specifying input for activity running on Provider node
• ways of obtaining/receiving output of activity running on Provider node

Important:

• this standard also specifies both “caps pattern” of specification, ie. how an Offer indicates capabilites supported, and what capability namespaces are there.
• the “caps pattern” shall define the versioning and backward-compatibility specification guidelines.
