Fabrication and prototyping using non-standard components can make design sharing and design modification costly and increase the cost of trial and error.
This tool aims to identify the various standards and systems to enable rapid changes in design, ease of reuse of components and reduced manufacturing cost and cost of specialized inventory
Modular Building Systems
The following are examples of modular building systems and standards that might be useful to the Farm Hack community
Open Source Ecology heavy weight structureshttp://opensourceecology.org/wiki/Warehouse
A warehouse of the components can be downloaded herehttp://opensourceecology.org/wiki/File:Warehouse.skp

A good article on the Open Structures approach can be found here:
Universal Quick hitches like the triangle and Bob Cat( SAE J2513) hitches also fall into the category of modular systems/standards
