Re: [linking-data] What do the links mean?

I don't know if this is the right place to bring this up, but something
occured to me when I looked at the description of Allen's algebra
<http://Allen's interval algebra> (used for temporal relations): the labels
for the relationships have similarities with 2D spatial relationships (e.g.
the DE-9IM <https://en.wikipedia.org/wiki/DE-9IM#Spatial_predicates>).
Which perhaps is no surprise - isn't Allen's algebra essentialy a way of
describing events on a line, i.e. a one dimensional space?

At the moment I don't have time for searching for research papers and the
like, but I wonder if a general model for n-dimensional relationships could
be used for expressing temporal and spatial relationships. The DE-9IM model
is for 2D space, but in 1D space (linear referencing) and 3D space there is
also a need for semantics that describe spatial interaction between
resources. A single base model could perhaps simplify definition of
spatiotemporal relationships, lessen the amount of required properties and
provide extra opportunities for reasoning.

Frans
