The Object Network


Things can be animated by visible rules which define their behaviours and interactions with other things. Rules enable your objects' states to be dependent on that of other local or remote objects that are visible via their links.

You could link to available custom rules online published by others, but more interestingly, you could write your own object rules to allow them to have any behaviour you like.

Here is a sketch of a possible programming interface for the Object Network. It shows how objects are bundles of properties at a link or UID. They can link to other objects with UID properties - shown as a nested object here. Lights and price tags (and contacts and calendar events, and 3D entities, and chat messages..) will be standard types that everyone can use.

This example shows a very simple rule built in this 2D interface, comprising two objects: a light in your home and a price tag in a local pet shop - an object that is hosted near a fish tank you want to buy:

A rule like this matches the conditions in yellow and rewrites the object when that happens - the right-hand side of the "=>" symbol.

The rule is 'animating' the light and represents its dependency on the price tag - when the price drops, the light goes red.

The rule would run on the light itself, or maybe a controlling host such as a house hub. The price tag would be running on a machine owned by the pet shop, and these two machines, or their two objects, will talk directly, peer-to-peer, to make this rule work.

If you can write spreadsheet formulae or HTML, you can write Object Network rules. These rules can be written in traditional one-dimensional text, or in a two-dimensional user interface.

This rule programming language is very high level in the sense that you don't need to do any work to write code for saving objects or to handle their network interactions. It also assumes the code to handle input and output is already in place - e.g. the light driver above, or user interfaces. You simply write your actual logic, in a very declarative way.

Objects simply link to the rules animating them. Rules are objects and would also update just like the stuff they animate, so can always be kept up-to-date.

Objects will depend on each other, like cells in a spreadsheet, and there will be ripples of updates across peers. Things can settle in their own time - which is more like reality and more robust. Pretty much anyone can program spreadsheets, and anyone will be able to program their own stuff in the Object Network in a similar way.

This open web of objects will form a system of local, autonomous, peer-to-peer relationships. The Object Network replaces lock-step central control with behaviour and interactions that emerge from local decisions. Rules are lightweight and work together so that behaviour and interactions emerge from many such small rules being applied or triggered on individual objects.
