Let's start with a protocol that may have similarities to the PAIR ontology: https://murmurations.network/ I just got the link, and here what they say at first:

The problem.

People often want to map the organisations in their sectors. But maps and directories which rely on people adding data to centralised databases are always out of date – because organisations move, change their web address or other details, and forget to update the directory.

The problems with centralised maps and directories include:

    •    Large amounts of manual effort required to identify and enter the information

    •    Difficulties sharing data between similar or overlapping maps and directories

    •    Difficulties keeping data up to date

    •    Organisations are required to update data on multiple platforms

    •    Fragmented, incomplete and outdated data frequently disappoints searchers

Centralised maps and directories can never be updated often enough to keep them relevant. Until now….

It will be discussed openly during one of the sessions on OpenCoop (11-12th June) https://open.coop/2020/04/02/open-2020-reinvented-networked-commons-initiatives/
