Not a lot of standardization in that field, especially in the mobile devices. At the transport level you do have MQTT and there are a couple of small efforts to build some standards on top of that. Most of the mobile stuff is binary, I've worked with devices from probably over a dozen manufacturers and you see a tiny bit of standardization around some ASCII with yea olde Hayes modem command sets and so called hex bin numerics. At the home level you're starting to see a few manufacturers gaining some traction, the Rockchip WiMo (Wireless Mobile Multimedia Transmission Protocol) has a fair number of devices and Google has some people jumping on whatever is behind the Nest devices. Lutron uses Telnet and a (proprietary) ASCII protocol which makes it very easy to work with.

There is an exploding growth of sensors. Here are a few examples of sensors:
- flood gauges
- air pollution monitors
- thermostat
- stress gauges on bridges
- mobile heart monitors
- traffic Webcams
Sensors take observations. For example an air pollution monitor periodically measures (observes) the air pollution.
How do we structure the data generated by a sensor? Has anyone created a _lightweight_ data format for observation data? If yes, are there tools to process the data format?
I am aware of the OGC's Observations and Measurements stuff. [1] It's nice, but I am wondering if there has been a bottom-up, grassroots development of a lightweight data model for observations?
