Re: [xml-dev] Lightweight, grassroots "observation" data format,with supporting tools!

I'm not sure there's much to be gained from standardizing sensor data formats as a whole. Standardizing time, quantity, and unit pieces might be worthwhile, but I don't see a point in trying to create a generic "sensor data" format.

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.*

    Hi Folks,

    There is an exploding growth of sensors. Here are a few examples of

    -       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?
