Aldo de Moor and I are rapidly approaching the end of our mid-week work retreat. The fresh sea breeze and the occasional glass of wine have helped us divide our attention between Real Work, and Serious Study. It resulted in an emerging framework or meta-model, with a few purposes:
- Advance our earlier modelling work with new insights, and assess where we think things are by now.
- Enable us to combine our years of experience in talking about various parts of the puzzle in a common structure.
- Provide an overarching framework to look at the various models we have come to use or see over time.
It’s very much still a work in progress, but while twittering about our progress, I got into a conversation (via Facebook) with John Bywater of the Appropriate Software Foundation, which helped me clarify a bit of my thinking. I met John just over five years ago at Summer Source, where he introduced me to the concept of pattern languages. At that time, it was still too abstract for me to apply in my actual work, but over the years, patterns have become more common-place, for instance in PHP programming and in wikis.
