such an API (RESTful interfaces down to the sensor level) is being 
developed in the SPITFIRE project (http://spitfire-project.eu/) using 
the ontologies developed in the SSN-XG, SSN-CG (SPITFIRE is an active 
contributor to these groups). APIs without proper semantic data / 
platform / etc. descriptions are insufficient, as are ontologies / data 
without APIs.

Also there are a number of upcoming de-facto standards for APIs: CoAP 
(Constraint Application Protocal - "HTTP for sensors") and CORE ("RDF 
for sensors") - both IETF and with major backing in the sensor world 
(both industrial and academic). It will be hard to find a meaningful 
niche between what the OCG has done already and what the IETF is about 
to standardize. Along with the upcoming networking standards (6LowPAN 
and the self-org stuff), this will set the agenda. This is the route 
which a number of initiatives and projects are taking (e.g., SPITFIRE 
uses some of the most advanced 6LowPAN, COAP, etc. implementations done 
by the project partners and uses RESTful interfaces and SSN down to the 
hardware level - and we have demoed this already).

Best regards,
