Baltimore Sun Public Salary Records (via) The Baltimore Sun have published an interactive search engine for public salaries of Maryland state employees, and it’s powered by Datasette! Since data journalism is one of my key use-cases for Datasette I’m incredibly excited to see this in the wild. They’ve also published the underlying source code (see the via link) which is a really nice example of how to use Datasette’s custom templates and canned query functionality. # 28th March 2018, 5:12 pm

Observable notebook: San Francisco trees from Datasette. I used an Observable notebook to rebuild my San Francisco tree search demo against a Datasette API of a CSV of trees published by the SF Department of Public Works. The map updates live as you type a query, and every cell can be toggled to view the underlying source code. # 1st February 2018, 12:37 am

Analyzing my Twitter followers with Datasette

How to compile and run the SQLite JSON1 extension on OS X. Thanks, Stack Overflow! I’ve been battling this one for a while—it turns out you can download the SQLite source bundle, compile just the json1.c file using gcc and load that extension in Python’s sqlite3 module (or with Datasette’s --load-extension= option) to gain access to the full suite of SQLite JSON functions—json(), json_extract() etc. # 10th January 2018, 9:01 pm

csvkit. “A suite of command-line tools for converting to and working with CSV”—includes a huge range of utilities for things like converting Excel and JSON to CSV, grepping, sorting and extracting a subset of columns, combining multiple CSV files together and exporting CSV to a relational database. Worth reading through the tutorial which shows how the different commands can be piped together. # 8th January 2018, 9:03 pm

Himalayan Database: From Visual FoxPro GUI to JSON API with Datasette (via) The Himalayan Database is a compilation of records for all expeditions that have climbed in the Nepalese Himalaya, originally compiled by journalist Elizabeth Hawley over several decades. The database is published as a Visual FoxPro database—here Raffaele Messuti‏ provides step-by-step instructions for extracting the data from the published archive, converting them to CSV using dbfcsv and then converting the CSVs to SQLite using csvs-to-sqlite so you can browse them using Datasette. # 8th January 2018, 7:26 pm

Building a location to time zone API with SpatiaLite, OpenStreetMap and Datasette

Given a latitude and longitude, how can we tell what time zone that point lies within? Here’s how I built a simple JSON API to answer that question, using a combination of data from OpenStreetMap, the SpatiaLite extension for SQLite and my Datasette API tool.

VICE News Police Shootings in Datasette (via) VICE News collected data on both fatal and nonfatal police shootings from the 50 largest local police departments in the United States. They released the data under a CC BY-NC-SA 4.0 license so I’ve converted it to SQLite and loaded it into Datasette. # 11th December 2017, 10:47 pm

Datasette 0.14: customization edition. I just released the latest version of Datasette with a strong theme of customization: Datasette now supports custom templates and CSS styling hooks, and the metadata format has been expanded to allow per-database and per-table source/license/description information. You can also now define named canned queries which will be packaged up with your data. # 10th December 2017, 1:55 am

Datasette: Ability to customize presentation of specific columns in HTML view. Still a work in progress, but Datasette master now allows you to inject links to one or more additional CSS and JavaScript resources (optionally with SRI hashes) which will be included on every page. Each template also now provides CSS classes on the body element derived from the current database and table names to provide hooks for custom styling. Next up: custom template support. # 30th November 2017, 7:27 am

Publishing the Lahman Baseball Database with Datasette (via) Ted Lawless used Datasette to publish an API for the Lahman Baseball Database—a dataset of players and teams spanning 1871 to 2016, available under a Creative Commons License. # 20th November 2017, 9:15 pm

If you’re a public data provider—and many large NGOs, government organizations, cultural organizations, historical archives, media organizations, medical orgs, and academic institutions are exactly that—you can publish gigabytes of data, and make it available as an API, and make it easy to browse on the web, too, with extremely low effort. Put it into SQLite, point this little guy at it, and you’ve just radically increased the accessibility and utility of your data. Because messing around in SQL from a web browser is orders of magnitude more immediately useful than downloading a CSV, processing it, and figuring out what comes next.

Datasette 0.12. I just released v0.12 of Datasette. The most exciting new feature is the ability to display a UI for editing named parameters—so you can construct an arbitrarily complex SQL query, include some named parameters and then link directly to it in Datasette to provide a simple interface for changing those parameters. An example involving Australian dogs is included in the release notes. # 16th November 2017, 3:55 pm

Plotly Falcon SQL Client and the Remarkable Datasette SQLite2API Generator. Lovely write-up of Datasette by Tony Hirst.
