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.

Hi Daniel,

Could you let me know once you've decided on a venue for discussion? I'd be
happy to join in.

Thanks in advance,
Peter.

Hello,  how many of us have github accounts?

Oh... both the Wikimedia lists are members only, I'm afraid. The W3C list
requires a 1-click agreement to their terms. That's easier, but less likely to
involve Wikimedia people.

Just a quick heads up that this is expected to go live next week. Since nobody
responded to the original announcement, we don't expect much trouble.

But if you are processing WKT literals from Wikibase RDF output, you need to
check the version number, and parse the literals accordingly.

Hi!

We are committing a patch that implements a change in RDF format output,
specifically how we output coordinates as WKT points.

If you do not use RDF format exports and specifically WKT coordinate
literals there, this change has no effect for you.

When we first implemented it, we chose to make it "Point(latitude
longitude)". Unfortunately, turns out the standard way in WKT is
Point(longitude latitude) and that's how most of the tools that
implement WKT format understand it. In general, geo-data formats are
split on this question, see http://www.macwright.org/lonlat/. But WKT is
pretty universally in lon-lat camp, so we have to follow the established
practice.

As such, we are changing the WKT representation and we are bumping the
format version (reported as schema:softwareVersion on RDF dumps/exports)
from 0.0.1 to 0.0.2 so that the tools could adjust properly.

See more details in: https://phabricator.wikimedia.org/T130049
