Hooray! The infochimps have been waxy’ed. Let’s see how the server bonobos stand up.
It’s been suggested that I highlight some of the “gems” of our collection, which we’re going to spend the whole weekend shoveling into the pile. These first few are really deep, and somewhat hard to get / not widely known:
- Full game state for every play of every baseball game in 2007, majors and minors. Additionally, for about half of the major league games, *pitch by pitch* trajectory and game state information. (MLB Gameday)
- Word frequencies in written text for ~800,000 word tokens (British National Corpus)
- All the wikipedia infoboxes, turned on their side and put into a table for each infobox type.
- 250,000+ Materials Safety Data sheets – the chemical and safety information required by OHSA
- 100 years of Hourly weather data; from 1973 on there’s about 10,000 stations all taking hourly readings … put another way, it’s 475,000+ station-years of hourly readings and weighs in at ~15 GB compressed.
(Incidentally, many of those datasets sell for inexcusable and malicious prices. For those with a commercial bent, something tells me there’s room in the market if you’re willing to accept a markup of less than 10,000 times).
These are a bit silly but interesting for their ridiculous depth:
* A variety of mathematical constants (pi, e, Catalan’s number, the Golden Ratio, others) calculated to in some cases a preposterous 100 billion decimal places (I’ll probably chop them off at a still-ludicrous 500 million).
* 5000 years of solar eclipse times, 6000 years of precise lunar phase, 6000 years of venus transits.
* Odds of Dying for every Cause of Death listed in the US in a given year.
There are also, of course, the well-known collections: IMDB.com, musicbrainz, dbpedia, CIA factbook, geonames, citeseer, census, statistical abstract and the like. So let’s see how much of the low-hanging fruit we can toss up there this weekend (the hard parts are adding metadata, and getting the non-copyrightable data out of the copyrighted screenscrapes, so what you’ll see are minimal metadata and the non-screenscraped datasets — still beats paying $1200+/GB though.)
[edit: dates for holidays by country, year-by-year odds of dying for all causes of death from the recent 8 year, NIST values for physical and chemical constants, mechanical properties of common engineering materials, and the spoken and written word frequencies for ~800,000 word tokens datasets should be up later today -- if the site is down briefly we're pushing that update to the server. (If the site is down not-briefly we've been del.waxyslashdiggdotted) Thanks to my friend Ned for helping do some drudge work to get those out.]
