Hi,
Somewhat belatedly, I can give an update on work being done of the drat Pattern Language
Attached is an interim, incomplete draft (WD02) of the TGF-PL deliverable.
Following the working group meeting held two weeks ago, I proceeded with the first steps in a methodology:
- Identify each and every conformance criterion in the TGF Primer
- From the criteria, identify possible “candidate” patterns;
- Add patterns that contribute to the whole;
- Remove patterns that are redundant or can be better expressed as part of a larger pattern;
I then started the work of transposing text from the TGF Primer to the Pattern Language document:
- Identify the core “imperative” statement for each pattern, based on the conformance statement in the Primer;
- Add text that relates a particular pattern to others;
- Add text that serves as the prose body of the pattern, taken from the Primer and other contributions;
- Add references back to the Primer where appropriate in the “completion” statement of each pattern;
As a result of a couple of cycles, the number of proposed patterns has gone up and down and has now stabilised at under 40.
The interim result attached reflects this process applied systematically.
As a result,
- the first 15 patterns are finished;
- another half dozen are nearly finished;
- the skeleton of the remaining patterns is in place
As I am “in the zone”, I’m happy to continue this tomorrow and should be able to complete another dozen or so of the patterns but after that I will be travelling for the remainder of the week.
Can I ask all members of the TC to:
- take a look and give any comments about whether the draft is going in the right direction;
- indicate whether the completed patterns satisfy the conformance criteria that we have nominally indicated in the Primer;
- submit any comments or queries on the nature and content of the document.
Can you also indicate whether you will be able to lend a hand at writing a few patterns, now that the structure and practice is clearer. As an indication, you should allow 30-45 minutes per pattern to go through the steps outlined above. I will continue tomorrow in any case, proceeding sequentially through the text. I will then only be able to return to this after tomorrow on Sunday 12th and Monday 13th.
If you are willing to write some patterns, please let me know, and I will send you the .docx file to work with.
For reference, we are due to decide at our TC meeting on Thursday 16th:
- whether to proceed with moving this working draft to a full “Committee Specification Draft” – which involves shifting the content to the new formal template and completing the set of patterns, at least as a first draft;
- agreeing a timetable to finish a first formal draft for adoption by the Committee and releasing it for public review
Best regards,
Peter
