For resource constrained sensors, there is an industrial standard,
called IEEE 1451. It offers a TEDS description about sensor, which is
prepared by the sensor manufacturers.
Within IEEE 1451.2, National Instrument has defined an electronic
version of TEDS, named VTEDS .
You should be able to follow the template to encode some common feature
One approach is to create mapping from TEDS to SensorML, as described in

In this case, the node carries its own metadata description, which can be queried when the node joins the WSN. Unfortunately, SensorML is far too verbose for this purpose, since these nodes may typically only have a few pages of flash memory available.
