Greetings,
Very interesting topic,
Would love to learn more about geo coding with Wikidata,
or maybe even about spatial modeling or creating significant improvements
into desired gazeteers &/or geodatabases. Ofcourse, I am not familiar with
much of the .rdf output,
but maybe we can talk about those summarized efforts towards retreiving
spatial attributes using
the Wikidata API >? (SPRQL).

Hi, One concrete usecase is the formula datatype for properties on
Wikidata. We are discussing the semantics issues here : what means the
operators of the formula, what means the variables ? An immediate way, in
Wikidata, is to
In the item for a geometric figure, for example a square, how to model that
a square can be defined in the euclidian space by the geometric coordinates
of points, we could create the item for a point class in Wikidata, give a
name of a point (pretty much usual mathematical or programming work) and to
link that variable name to an item for the semantics/corresponding type.
Same for the operators.
Last, in the question you raised on "modelling maths versus modeling domain
model formula" I'd say that in Wikidata the scope is basically unlimited,
contrary to a regular scientific publication who takes place in a context
that may be more or less non formally explicited, we can fill the gap
beetween more formal aspects of logical or inference rules used by the
scientist, the mathematical framework (euclidian space, non euclidian
space, logical framework, axioms ... we pretty much have items for all of
this and can create new one if that's structurally needed for a usecase)
and the formula. Time is less of an issue because the work is reusable and
cumulative, there is no deadline. There is only a need to leave the door
open to do that work for someone to be able to do it at his/her convenance.
Of course it's a lot of work, but there is no pressure. I'm not sure how
MathML relates to this however.

Peter just posted a follow up response, largely
commenting on my
response:
https://www.peterkrautzberger.org/0187/.
First, I suspect the reason his post doesn't get as much discussion as
he'd like is because his blog doesn't accept comments. I can understand
why
he doesn't enable comments on his personal
blog but why not post it
somewhere that DOES accept comments?
He says that most of the discussion has been private. That is not the way
to change a standard or replace it by a new one. By all means have your
private conversations but don't expect others to agree with any
conclusions
reached in them. The result of good ideas
expressed in private
conversation
should be to introduce them into public
conversation. Instead, his post
treated MathML's failure as a fait accompli. Perhaps it is but only in
the
narrow scope of it being ignored by browser
makers.
He feels that many things I said in my reply were more about expressing
my
own ideas. I'll cop to that. I felt that was
needed to indicate that
there
are other points of view and other ideas. His
solutions may not be the
right ones. Let's open up the discussion.
Can we identify specific topics worthy of addressing and discuss them? I
tried to hint at some possible directions in my reply, which is why it
veered into some of my own ideas. I would love for this to be a
constructive discussion. Instead of discussing whether MathML is a failed
standard, I would like to see real, open discussion on solutions to
various
problems. Any takers?

I have no problem with that but are some of these lists members-only? I
was

wasn't a member. Perhaps that was the W3C list.
