Representing defining and using ability competency and similar concepts

By Simon Grant, 2009-01-04, attempted some very rough updating, 2018-10-12

These web pages together form a position paper, setting out my current views on a good way of tackling these issues. The position is not fixed, and it is my hope that people will respond to these concepts, either directly by e-mail as a result of reading here, or through replying to blog posts on the topics, to point out any errors, any difficulties with what I suggest, or better approaches. I will be very grateful for any useful contributions, and will acknowledge them.
