Good practice for RDF publishing of multiple geometries with different CRSs?

Hello,

In preparation of publishing a dataset as Linked Data I am faced with a
recurring problem: in which way can I publish a geometry with multiple CRSs
?

This requirement is captured in the UCR document and will hopefully be
tackled by the BP document and would probably be solved if we develop an agreed
upon spatial ontology
<https://lists.w3.org/Archives/Public/public-sdw-wg/2016Mar/0057.html>, but
perhaps it is possible to think of a good solution now that will help
further progress?

The problem is as follows: As a data publisher, I want to publish geometric
data in additional reference systems next to the source CRS, as a
convenience for consumers. So data could look like this (in Turtle, using
the Core Location Vocabulary and GeoSPARQL) :

ex:location1234
  a dcterms:Location;
  locn:geometry "<http://www.opengis.net/def/crs/EPSG/0/28992> POINT(139715
476443)"^^geosparql:wktLiteral
  , "POINT(5.1633 52.2758)"^^geosparql:wktLiteral .

In this example, the source data use the Dutch national reference system
and the geometry is published with CRS84 too. A user (for example a web
developer that wants to be able to plot the data on a map, or a researcher
that want to combine the data with other spatial data) will typically be
interested in using only one CRS. How can a data consumer get the geometry
data in the preferred CRS? And what can de data publisher do to accommodate
that?

Does someone have a good idea of how to do this?

Frans
