Photon Datum

Overview

How it fits together

Status: In Review

From the people who use it, through the front door and Datum Core, to the machines that run the models.

How Photon Datum fits togetherPeople at the top reach the front door: the website, the portal and single sign-on. Below is the secured model network, a circle with Datum Core at its centre and the member services, agent tools, search, the model gateway and the model nodes around it. On the left, a computer running Synod on its own; on the right, a computer running Synod that is also on the network.

Three ways to take part

  • Synod on its own. Synod and Datum Core on your own computer, with local models. Your machine is not on the model network.
  • Synod on the network. Your computer runs Synod and is also enrolled on the secured model network: it can use the network's models, and can add its own.
  • On the network only. A machine that only joins the secured model network to run models for it. No Synod; ours today, and in future, machines that members contribute.

Access

  • Members. Signed in through the portal with single sign-on.
  • Private network. The secured Datum Core model network. Encrypted, with no public address: reached through the portal, or by a machine enrolled on the network.
  • Your machine. Runs on your own computer and listens on that computer only.
  • Public. Open to anyone on the internet.

How a request travels

A member signs in once at the Photon Datum Portal, which uses single sign-on, and opens a service from there. When you send a message in Photon Datum Chat, it goes to Datum Core, whose model gateway passes it to a model of the right size on one of the model nodes. The member services, the gateway and the model nodes sit on a secured, encrypted network with no public address: the only way in is through the portal, or by a machine that has been enrolled on the network.

The three ways to take part, A, B and C, are explained under the graphic.
