So… the UK Gov started publishing spending data for at least those transactions over £25,0000. Lots and lots of data. So what? My take on it was to find a quick and dirty way to cobble a query interface around the data, so here’s what I spent an hour or so doing in the early hours of last night, and a couple of hours this morning… tinkering with a Gov spending data spreadsheet explorer:
The app is a minor reworking of my Guardian datastore explorer, which put some of query front end onto the Guardian Datastore’s Google spreadsheets. Once again, I’m exploiting the work of Simon Rogers and co. at the Guardian Datablog, a reusing the departmental spreadsheets they posted last night. I bookmarked the spreadsheets to delicious (here) and use these feed to populate a spreadsheet selector:
When you select a spreadsheet, you can preview the column headings:
Now you can write queries on that spreadsheet as if it was a database. So for example, here are Department for Education spends over a hundred million:
The query is built up in part by selecting items from lists of options – though you can also enter values directly into the appropriate text boxes:
You can bookmark and share queries in the datastore explorer (for example, Education spend over 100 million), and also get URLs that point directly to CSV and HTML versions of the data via Google Spreadsheets.
Several other example queries are given at the bottom of the data explorer page.
For certain queries (e.g. two column ones with a label column and an amount column), you can generate charts – such as Education spends over 250 million:
Here’s how we construct the query:
If you do use this app, and find some interesting queries, please bookmark them and tag them with wdmmg-gde10, or post a link in a comment below, along with a description of what the query is and why its interesting. I’ll try to add interesting examples to the app’s list of example queries.
Notes: the datastore explorer is an example of a single web page application, though it draws on several other external services – delicious for the list of spreadsheets, Google spreadsheets for the database and query engine, Google charts for the charts and styled tabular display. The code is really horrible (it evolved as a series of bug fixes on bug fixes;-), but if anyone would like to run with the idea, start coding afresh maybe, and perhaps make a production version of the app, I have a few ideas I could share;-)
