DataBrewer

The missing datasets manager.

Databrewer let you search and discover datasets. Inspired by Homebrew, it creates and index of known datasets that you can download with a single command. It will provide an API to allow to do the same in, for example, a IPython notebook so you no longer have to manually download datasets.

Quickstart

Install databrewer:

pip install databrewer

Update the recipes index:

databrewer update

Search for some keywords:

databrewer search nyc taxi

Example output:

andresmh-nyc-taxi-trips - NYC Taxi Trips. Data obtained through a FOIA request
nyc-tlc-taxi            - This dataset includes trip records from all trips
                          completed in yellow and green taxis in NYC in 2014 and
                                                    select months of 2015.

Let's check the nyc-tlc-taxi dataset:

databrewer info nyc-tlc-taxi

We can either download the entire dataset (which is huge!):

databrewer download nyc-tlc-taxi

Or just a few files in the dataset, or select a subset:

databrewer download "nyc-tlc-taxi[green][2014-*]"

Finally you need to know where the files are located for further processing:

databrewer download "nyc-tlc-taxi[green][2014-*]"

Example output:

Datasets

The aim is to index known and not-so-known datasets. There is no plans to standarize the dataset format as we want to keep it as published by the authors.

Recipes

Datasets are defined in recipes which contains information about the dataset and where to find it.

These recipes are community maintained and hosted in the databrewer-recipes repository.

Roadmap

• Include an API. For now it only provides a CLI-interface but in the near future it will include an API so you can search, download and load datasets directly in your Python code.

Contributing

You can help by the following means:

• Spread the word!
• Request missing features
• Report usability issues or bugs
• Request missing datasets
