Re: [xml-dev] Lightweight, grassroots "observation" data format, withsup

[Peter Hunsberger <peter.hunsberger@gmail.com>]

Having worked on a system that supported several 100 different devices I know some standardization could sure help.  The actual contents don't necessarily need to be standardized but standardized containers, protocols, and schema / meta languages sure would help.  Something like EXI would have made out jobs way easier...

Some of the manufacturers (in the satellite world in particular) also make a tidy profit by supporting their own gateways or more fully featured service endpoints to do conversions from some proprietary binary format to something like XML. For example, Digi will be happy to charge you a dollar (or maybe less) per device and give you a cloud based API with persistent storage behind it. Seems cheap until you do something like put a couple of devices in every office in a couple dozen buildings. You can usually roll your own handlers for the binary formats, there are usually some docs, but the XML formats are trivial to implement.

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.

Thanks,
