What worked: AIDG Technology R&D Document Series

AIDG’s Technology R&D Program is pleased to present a new series of technical documents that have been produced during various projects we have worked on in the last 5 years. During the first 3 years of the program, the documentation was produced in a haphazard way, but around the beginning of 2008 we realized that that wasn’t going to provide a good base for future work the way that more systematic documentation could. Since that point, we have tried to document projects more thoroughly as they are ongoing, so that the information isn’t lost and we and others can build on the work that has been done. During the last year, we have been extremely lucky to have intern Ben Dana undertake the arduous task of pulling together information from many of the previous projects and put into one place.

In presenting these documents, we would like to accomplish two things. First, we would like to provide anyone who is interested the opportunity to learn from our mistakes and our successes, to see a bit of the process we have gone through in different development projects, and apply those lessons to their own projects. Second, we would like to tap into the worldwide appropriate technology community and stimulate further development of the technologies we have worked with.

We’re still developing a plan for how to best stimulate this type of development. In the next few months, we hope to pursue alliances and implement tools to allow the information to spread as far as possible, to encourage people to do further work, and to provide a forum for discussion of that work and presentation of results. In the meanwhile, we’d like to present several documents, and we invite everyone to comment on them, on anything and everything that comes to mind. We’re looking for feedback on format, appearance, the type and quantity of information that the documents contain, and anything else.
