Hi, thats an interesting subject.matter. For her phD a friend of mine worked on documenting fractals in an African community.

With research approach or techniques, you have got to decide methods are best to answer your research qquestion, and fulfill your

study's aims and objectives. My friend employed a cultural eeconomics perspective, and documented indigenous designs using maps, diagrams, pictures and video.

I hope this helps?

ITK is memory based knoweldge for this purpose questionnaire can be prepared and survey can be conducted and that can be documented.
