About the data
Nearly every number on Wet Wicket starts life in Cricsheet, one of the great gifts to people who love cricket.
Cricsheet
Cricsheet is a collection of projects that provide freely available, structured data about cricket. Stephen Rushe started it in 2009 and still runs it. It publishes ball-by-ball records for Tests, one-day internationals, T20 internationals and dozens of domestic and franchise competitions, men's and women's. There are more than 22,000 matches in all, and new matches are added as they are played.
Cricsheet also maintains the Cricsheet Register, which gives every player and official a unique identifier and links it to the identifiers used for the same person on ESPNcricinfo, CricketArchive, the BCCI and other sites.
If you find Cricsheet useful, visit the site and tell Stephen. If you spot an error in the underlying data, Cricsheet is the place to report it.
Licence
Cricsheet's match data and register are made available under the Open Data Commons Attribution License 1.0. Wet Wicket's datasets, charts and analyses are works produced from that data, and we attribute it on every page that uses it. If you reuse a dataset from Wet Wicket that is derived from Cricsheet, the same licence and attribution apply to you. The licence covers the data. The site's code, design and writing are not open source, and all rights in them are reserved.
What we do with it
We download Cricsheet's JSON match files and register, load them into our own database, and derive everything else from there: rain flags, over-by-over states, rain-rule replays and the like. Where we add information that Cricsheet does not hold, such as the host country of a ground, we say so on the page. The code for all of this is public on GitHub, so you can read how each dataset is made.
We check Cricsheet for new matches once a day and download only files that have changed.
Provisional matches
Cricsheet publishes in batches, sometimes a week or more apart. Until a recent match arrives from Cricsheet, the Archive may show its result and innings totals from CricketData.org, marked provisional. Cricsheet's record replaces it as soon as it is published. Provisional matches have no scorecards, are left out of every dataset and analysis on the site, and are not covered by our data licence.
What is not included
Cricsheet currently withholds matches involving the Afghanistan men's team and the Afghanistan Premier League, as explained on its downloads page. Those matches do not appear on Wet Wicket either.
