Hi Deirdre,

I'm wondering if we could use a non-semantic web example for a data subset
to hit a wider audience.  Peter found an example for real time data
collection for river level monitoring.  The API offers access to current
(pun intended e.g. live) data as well as archived csv data containing all
measured results.  The data subset example could simply be an API that
selects a subset of archived data over a date range (e.g. yesterday).
