DataBrewer¶
The missing datasets manager.
- Free software: MIT license
- Documentation: https://databrewer.readthedocs.org.
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-*]"
Note
Note that * is the standard glob operator and [green] acts as selector.
The selectors depends on how the recipe if defined. When using selectors you
must enclose the name in quotes in most shells.
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.
