Hi Seth,
I think we're basically in agreement. The hard truth however is that
it is unlikely that we will get to something as flexible as mind-
mapping in the 1.0 timeframe (as an in-house project). It would be an
excellent idea as a "view" extension to Chandler however. It's one of
the projects I proposed to Ted to pass on to OSU's Open Source Lab.
In the meantime, we're looking for ways we can improve aggregate
views of data with the affordances we have today: ie. table and
calendar (via the application of some of the visual design principles
outlined in the wiki write-ups).

The proposed topic of this thread was to explore ways of visualizing
this data/content model in a way that is easily comprehensible for
both personal use as well as collaboration.
You can import information of all sorts into the highly generic
framework of relations described as use types, linktypes, uses,
links and their attributes. Then all of them are intrinsically
interoperable. And my point is that these generic notions can
provide the conceptual backbone for the interface, a framework
that is easily understandable, which you make accessible to the
user within any interface you build.
It feels like there are a couple of threads running through your
comments below, let me see if I can address them individually (please
correct me if I misrepresent what you said):
+ I agree that our approach is to focus on end-user comprehension of
data visualizations.
+ I agree that this approach is not at odds with ideas about mind-
mapping. Instead it is intended to improve on mind-mapping UIs.
+ The generic framework you describe exists today in Chandler's data
model (see comments above). I think I was a little confused by your
comments because that wasn't the proposed topic of this thread.
+ In your last point, are you saying that mind-mapping IS easily
comprehensible without further improvements? This would be
interesting to explore further in relation to the design principles
laid down in the wiki write-ups.
A better response than my previous reply:
When I say:
I mean the way you're thinking is in terms of trying to find some
functionality that the app will provide, that will do the
simplifying for grokking that you seek. I suggest that thinking
this way foreshortens:

3) for mindmapping again, seeing that mindmaps are great for
grokking on the basis of seeing nodes' grouping and arranging and
interpreting that as a human, rather than the app understanding
the grouping and arrangement.
. . . I mean yes, it IS easily comprehensible. I also suggest
some further improvements, specifically to add the semantics you
point out are missing. Since the page in question is about
chunking over time, I'll beg off the visual interface design
question for now and continue to point out some things about data
architecture with respect to genericity, grokkability and
mindmapping. I just added the following comments to the page
(http://wiki.osafoundation.org/bin/view/Journal/ChunkingOverTime):

What I think I'm saying is that you can have a generic data
structure and also have semantics. Mindmapping software does not
currently have this, but there's no reason why it can't be added.
The "IsRelated" generic relation can be expanded to terms that
allow users to apply specific semantics to specific relations.
Instead of:
"this node is related to these children"
we have:
"this particular use (Make a birdhouse) of this particular use
type (Woodworking project) has these particular links (get some
wood, measure it, cut it, hammer it together) of this particular
link type (Project steps)"
When people begin sharing contexts defined by these abstraction
they will begin using common use types and link types, thereby
allowing chunking over time that's interoperable. One user will
be able to chunk over time any way she pleases.
Mindmapping in which each branch can be designated with specific
use types and link types, making them each unique relations,
would let you play with information and also begin to make
information usable across particular contexts.
Add to that the ability to visually represent specific such
combinations of use types and link types in their own assigned
default ways. Then make the visual interface (whether mindmap,
email folder, Gantt chart or any other visual interface) provide
access to the use types and link types of the relations.
This doesn't answer the design question of how to visually
represent such disparate types of relations, whether all at once
in one interface or in separate ones, but I hope that it does
give an idea how you can have completely generic relations and
semantics at the same time.
Now, regarding mindmapping -- this interface gives users the
ability to arrange things visually to see relationships by
grouping and to work with and access information that's in flux
as far as how it will ultimately be organized, even if to the
application there are no special semantics to the relations being
created. Now, to add semantics as I describe above and below,
would only augment the traditional mindmapping concept and
interface, as well as all other interfaces. Plus provide the data
structure for chunking.
One note: taking chunking as a function of our human ability to
comprehend visual information, we can observe that mindmapping
naturally leads to that, though without semantics in the
traditional form.

I mean the way you're thinking is in terms of trying to find some
functionality that the app will provide, that will do the
simplifying for grokking that you seek. I suggest that thinking
this way foreshortens:
1) for mindmapping, seeing that it's the particular kind of
functionality it provides that makes it valuable, moreso than the
criterion of how well some functionality intended to simplify
grokking, meshes with mindmapping functionality;
2) thinking about how more genericity in conceptualizing
information, not some function, might give you a better framework
for getting to better grokkability; and
3) for mindmapping again, seeing that mindmaps are great for
grokking on the basis of seeing nodes' grouping and arranging and
interpreting that as a human, rather than the app understanding
the grouping and arrangement.
