Re: space and time

TL;DR This post is not straight on the point, but displays my personal
associations to the topic.


Hallo Frans,

I feel a little intruiged by the coincidence that you are asking about
time now only a few weeks after I joined this list.
Why that? Because I've entered mainly to answer myself questions
regarding spacetime relations.

I have the strong feeling, esp. for my research on knowledge
visualization and tempospatial patterns therein, that a more thorough
investigation and understanding of time itself can help representing,
in my case, distributed processes in a more meaningful manner.

I'm just starting to explore this topic for me, as there are only
scattered notes, but to merge everything I find right now they are:

* levels of measurement
  * probability / discrete / continuous ( wiki://Quantum_spacetime )
* geogit
* ActiveRecord's tempospatial engine
* WIK DVCS - patch-based version control for the Federated Wiki (
including Transclusion, etc. )
* SMILIE Timemap, Sextant, OKFn Timemapper

There is work I know on those issues, mostly derived from the
conferences I attended this year, since I just started exploring:

[ via CartoCon 2014 ]
* tempospatial reasoning -
https://people.aalto.fi/index.html?profilepage=isfor#!andreas_hall
* Barend Köbben's work - http://kartoweb.itc.nl/kobben/ - check
Showcase > D3 examples
* tempospatial models in PostGIS - via Raimund Schnürer -
http://www.ikg.ethz.ch/karto/people/staff/sraimund

[via FOSSGIS 2014 ]
* Time Slices ( AIXM related ) -
http://www.fossgis.de/konferenz/2014/programm/events/745.de.html
* tempospatial models in GRASS ( via OSGeo )

[ via OuiShare Fest 2014 / Harry Halpin ]
* Linked Geodata Activist Phil Archer which I still have to contact.
* A Catalog of Temporal Theories - by Pat Hayes -
http://www.ihmc.us/users/phayes/docs/timeCatalog.pdf

[ #lgd14 was also a very resourceful event, but I haven't been there ]
* Strabon as a semantic tempospatial engine designed from ground up
http://www.archaeogeomancy.net/2014/03/linking-geospatial-data/

I think I will be filing in a paper for #geold14 /
http://geold.geoknow.eu/ discussing
* existing time-space ontologies
* relation to geojson-ld
* calendar / timezone agnostic time

All this becomes important when I want to draw distributed processes [
persons, organizations, projects, knowledges, resources, ... ] along
topological, temporal or spatial scales.

Outside of the technological interest, the philosophical implications
also appear interesting:
* How can a non-linear time-model serve a processual democracy?
* Do we already understand time enough to use historic prepositions
for time modelling?

Sorry for being so scetchy, but I'm just a beginner in this topic.
But maybe I'm following a good trail here?

Interested in any further exchange,

Jon
