I'm very looking forward to Krems, and to your corresponding
contribution.<br class="">
<br class="">
I see that we use different terminology, though. <br class="">
<br class="">
So, this posting tries to clarify our terminologies, <br class="">
maybe as a step to unify them. <br class="">
<br class="">
What you name meta-patterns is to me "patterns of pattern
research".<br class="">
I see a different design target, e. g. a PROJECT PATTERN
DISSERTATION.<br class="">
There are different patterns used, but I see no serious difference
in the <br class="">
quality of patterns or methodology that would justify a new
concept.<br class="">
<br class="">
For example, there is a PATTERN REPOSITORY (as a dirty research
workshop,<br class="">
containing patterns and pattern candidates, mature and not, and
all kinds <br class="">
of background information; as a basis for collaboration and
supporting <br class="">
the creattion of many different pattern products). <br class="">
I assume PATTERN REPOSITORY is a meta-pattern in your sense.<br class="">
<br class="">
Corresponding is the PATTERN PRODUCT, a meta-pattern in my sense.<br class="">
This is an abstract categorial construction.<br class="">
It has has real patterns as instances:<br class="">
e. g. PATTERN LANGUAGE BOOK<br class="">
e. g. PLOP PATTERN PAPER<br class="">
e. g. PATTERN CARD STACK<br class="">
...<br class="">
<br class="">
Meta-pattern is a pattern abstraction, <br class="">
where the problem-solution-relationship is lost. <br class="">
<br class="">
For example, <br class="">
RAILROAD STATION<br class="">
SCHOOL BUILDING <br class="">
are clear problem-solution-patterns. <br class="">
<br class="">
If we abstract from these concrete patterns, and talk about
BUILDING<br class="">
as a pattern (which shouldn't this be possible?), the problems are
lost. <br class="">
Although we may safely assume that each BUILDING solves<br class="">
a problem, we can't name it, and can't reason about it. <br class="">
Therefore, BUILDING is not a real pattern, it is something
different !!! <br class="">
Therefore, currently I talk about BULDING as a meta-pattern,<br class="">
lacking a better word.<br class="">
<br class="">
Often the discussions in communities seems move to this
"meta"-level<br class="">
and loose contact to real implementation issues. And one has<br class="">
to try to bring it down to the concrete level to find solutions.<br class="">
<br class="">
Do you see these phenomena too?<br class="">
Have you named them? <br class="">
<br class="">
Best,<br class="">

<div class="">Domesticating Pattern Languages<br class="">
Meta-patterns and the Development of Pattern Language Use
Methodology <br class="">
<br class="">
Douglas Schuler<br class="">
Aldo de Moor<br class="">
<br class="">
In the 2014 PURPLSOC workshop Schuler presented eleven “seeds”
as challenges that must be addressed if pattern languages are to
effectively promote social change. Here we focus on two
seeds: meta-patterns and methodology. Meta pattern languages are
pattern language whose domain is pattern languages. In theory
this pattern language could be used to help design workshops and
games, construct sub-languages using existing and new patterns,
and manage ongoing pattern-based projects. Existing pattern
languages capture essential lessons and linkages between those
patterns. However, those patterns are somewhat idealized and
"frozen." To use them in actual situations, stakeholders must
select the right patterns, ensure their suitability and
customize them, and develop and execute a plan. In practice,
such appropriation leading to effective use does not happen by
itself: stakeholders need additional guidance. We identified
candidate meta-patterns themes that include all aspects of
possible pattern use life-cycles, including pattern creation,
evaluation, planning, problem-mapping, project generation, etc.
In the context of teaching a college program using
the Liberating Voices pattern language we gathered information
at various stages of 10 quarter-long group projects,
including what types of projects they are proposing, which
patterns they selected for use in the project, and how they used
the patterns — and why. We believe that a closer look at
how patterns are used (in the fullest sense) will help identify
meta-patterns and how these meta-patterns are used together will
help identify methodologies and other approaches to more
effective pattern use.</div>
