Demone for the coordination. • Melissa Belvadi, Don Moses, Alkarim Bhalesha and Jerrad Gilbert at Robertson Library for digital logistics here in the lab.

the web • The “markup” adds meaning to text, like “make this a big title”: <h1>Who left the lights on?</h1> • On any page on the web, you can “View Source” to see the HTML of the page
by almost all web browsers • Allows “interactive stuff” to happen in the browser • Simple and easy to learn, like: var temp_c = 0; var temp_f = temp_c * 1.8 + 32;
passing data around the web. • The “fat-free alternative to XML” • Very easily used by JavaScript because it’s a subset of the way objects are represented in JavaScript.
be (only) human- readable • Open data on the web works best when… • it’s simply attached to a URL • it’s in an easily-manipulated format • it’s easy to understand
Operator • Organizations that manage the electricity network • Like the “switchboards” for the electricity network, which has been called “most complex machine ever devised by man.” • For PEI the network is managed by the NBSO: the New Brunswick System Operator
“open enough” • There’s not enough structure to the data, especially if I want to use it with other tools (to archive it, to graph it, etc.) • Solution: convert the HTML into JSON.
am very grateful that you have found a way to record the load and wind power generated in PEI. Do you by any chance have a spread sheet of these values? I am looking at using storage to balance wind fluctuations and was hoping to try and using the real load and wind data to accomplish that.”
web- connected, touch-screen computer • Uses the JSON version of the PEI load and generation data • Provides simple feedback: red - bad time to use energy (no wind, fossil) yellow - average time to use energy green - good time to use energy (high wind)
in real time? • Can we display this usage information to people in the house? • Can we use social pressures and a feeling of competition to motivate a decrease in consumption?
containing a radio receiver capable of reading and decoding electricity and water meter readings. • The readings can be processed by almost any computer, including a Raspberry Pi.

with water and electricity meters and wireless Internet. • Households okay with sharing their consumption data with others in the test group and with the public.

of wiring together devices and data. • No programming required. • Runs locally on your computer, and is accessed using a web browser on your computer. • The Social Consumption Project Raspberry Pi computers use it to read and upload electricity and water meter data to the web.
the load, the generation, and the generation mix I want everyone to have a gut feeling for whether it’s a good time to use electricity or not I want to have a gut feeling for my own load ✔ ✔ ✔
will use your open data for (maybe they will make music from electricity). • Reduce as many barriers as possible to easy, painless access to data: find the right format(s) and put the data right on the web, with a URL. • “Eat your own dogfood” – develop systems that consume you own open data.
