Intro

A core element of this development model is a principle called 'copyleft'  (symbol: ) which is a way of applying copyright to a creative work in a way that makes sure that anyone can freely use it or build upon it - and also that derivative works inherit the same terms, ensuring anything based on the original is freely available too. This principle means that 'copylefted' items – whether they are designs, text, artwork or computer code – are effectively gifted to humanity, adding to an ever increasing universal 'commons'. Because this principle is to the benefit of everyone, it completely changes the way that many people think about contributing their time and effort to this type of project. It already works very effectively with many high profile, successful software projects, so this is not merely wishful thinking.

Open collaborative design is a nascent field that has huge potential to radically alter the way we create goods, machines and systems – not only for personal items but all the way up to components of national or global infrastructure.

Open source applied to the physical world

The simplest method is to share information through a website on how to make things using text, diagrams and photographs. A more sophisticated way to collaborate on complex machinery and products would be to share CAD assemblies much like project teams do in engineering and product design companies, knitted together with supporting information in an open and freely structured environment, much like a wiki .

There are certain barriers to overcome for open design when compared to software development where there are mature and widely used tools available, and the duplication and distribution of code cost next to nothing. Creating, testing and modifying physical designs is not quite as straightforward because of the effort and time required to create the physical artifact. However the physical world is catching up fast with the virtual world in this respect.

Vast libraries of machines and components

As in software, it would be useful for components and assemblies to be as 're-usable' as possible in the sense of being able to be incorporated in many different machine designs. To aid this it should be possible to specify the vital dynamic functions of a component or assembly in the CAD software, so that it can easily be modified in shape and scale so it can be incorporated into a new design while ensuring it still works correctly.

This will enable a huge reduction in duplication of effort and allow people to focus their efforts on creating new machines of increasing complexity and building on the work of others.

One interesting side-effect of open collaboration is that it tends to lead to highly modular design. FireFox and Linux are examples of this. Modularity also leads to a high degree of reusability; someone designing a new piece of hardware or software can pick-and-mix parts of existing projects. This works well in software, but may have to be abstracted somewhat to work in physical systems where dimensions are obviously important to fit with other components.

Free and open-source software

Perhaps not counting the scientific community, free and open-source software is where the modern concept of commons-based peer production  really took flight. It is becoming very prominent in the world of software development with Linux, Firefox, Apache and OpenOffice being some high-profile examples.

Networks of people (both companies and individuals) collaborate via the internet to develop useful software that others can freely benefit from. Not only is the software free to use, but so is the human-readable blueprint of the software, known as the source code . Anyone capable is free to customise or help improve open-source software, and making these changes available to others also encourages rapid development times, robustness and reduces duplication of effort.

People who doubt the viability of the principles outlined on this page in the real world only have to look to this sector to see amazing examples of what is being achieved already.
