Free and open-source software/Beyond software
With a few built-in mechanisms to make sure the project doesn't dissolve into total chaos, the result is that this pool of knowledge is assembled and edited by people who want to do it and is now an amazing resource for anyone wanting a basic introduction to almost any subject. No-one is paying them to do it and no-one is telling them to do it, they contribute because they want to. It feels like the right thing to do - they are contributing to something greater. Contributors' know their efforts will be used and appreciated by thousands of other people, and that others are doing likewise. It is worth noting that like all encyclopaedias Wikipedia is not a 'primary source' for information and should be considered only as providing a useful introduction to a topic. It is always worth cross-referencing information from other sources too.
It is apparent that these methods could also be applied to the design of physical machines and artefacts. With this development model designs, photos, instructions and CAD models are stored on the internet for others to use and improve upon. Design and engineering is arguably even more suited to this method than software design. This is because looking at a CAD model, especially if animated, allows an intuitive understanding of how the object functions, whereas software is composed of reams of (often obscure) programming code. Architecture is another area well-suited to open collaboration, as the Open Architecture Network has proved.
- Open collaborative design and free and open-source computer-aided design for information on applying the open-source method to design and engineering
- Collaboratively generated educational material in the education section.
- - a non-profit organization devoted to expanding the range of creative work available for others legally to build upon and share.
