Atrium / Sharing

Atrium: sharing between lodges

Atrium lets you connect lodges so they can easily share documents, events, and contacts. No more manual back-and-forth: once lodges are linked, sharing is smooth and secure.

Whether you want to connect two lodges, join a thematic community, or work with your obedience, Atrium adapts with three types of groups: point-to-point, communities, and obediences / federations. In all three cases, Atrium is at the heart of the exchange and is represented in the same way.

Atrium is built on a professional cryptographic layer: only authorised instances can access the exchanged data, and the confidentiality of personal data is preserved end to end.

Point-to-point: two lodges connecting

When two lodges want to link to share documents, events, or contacts without a broader community, they can create a point-to-point link. The two lodges are then connected via Atrium, which routes and secures the exchange.

This is the simplest setup: no intermediate structure, just the two lodges and Atrium between them.

Communities: sharing within a lodge network

A community is a group of lodges that have chosen to share content automatically. When a lodge joins a community, it can:

• Share documents with other lodges in the group (invitations, minutes, reports…)
• Publish events (meetings, banquets, conferences) so other lodges can see and register
• Exchange contacts (members, visitors) in line with privacy and inter-lodge agreements

Everything happens automatically once links are active: you choose what to share, and other lodges receive the information without extra steps.

The diagram below shows all lodges linked to Atrium: each lodge is represented by a small temple, and Atrium appears as the central network connecting them.

• Centre: Atrium (the network that connects the lodges).
• Around it: member lodges, each represented by a temple.
• The lines represent the flow: documents, events, and contacts are exchanged in an organised, secure way between lodges via Atrium.

You stay in control: you decide which lodges are in the community and what you share with them.

Obediences and federations: lodges and a central instance

Obediences (or federations) are a special type of community. They include both lodges and an obedience instance (headquarters, central administration). The structure is: the obedience instance at the top, Atrium in the middle (linked to the obedience), and the lodges at the bottom, all linked to Atrium.

Exchange can happen in three ways:

1. Between lodges: as in a standard community, lodges can share documents, events, and contacts with each other.
2. Between lodges and the obedience: lodges send the obedience useful information (reports, lists, events) and receive in return circulars, official documents, federal calendars, etc.
3. Between the obedience and the lodges: the obedience distributes to all lodges (or a subset) the documents and events it wants to share.

This gives an obedience an overview while each lodge continues to run its day-to-day with Janus. Lodges remain autonomous while staying connected to their structure.

In short

• Atrium = the link that lets lodges (and optionally an obedience) share without the hassle. It is at the centre of every diagram, in the same way.
• Point-to-point = two lodges connected directly via Atrium.
• Communities = groups of lodges that automatically share documents, events, and contacts via Atrium.
• Obediences / federations = an obedience instance, Atrium, and the lodges; exchange in every direction.

Everything is designed to be easy to use and clear even if you are not technical: once links are created and accepted, sharing becomes part of everyday use.
