Requirements for Publish/Subscribe Application Format (PSAF)
Publish/Subscribe (PubSub) is an established communication paradigm where senders do not communicate information directly to intended receivers but rely instead on a service that mediates the relationship between senders and receivers. In PubSub senders (called Publishers) post information on and receivers (called Subscribers) declare their interest in a certain type of information – before or after a publication – to a service.
This document collects the requirements to be satisfied by the payloads utilised by a Publish/Subscribe mechanism for media applications.
