Collect data from popular data repositories with ease.

PyCurator

Making data extraction and curation as easy as py.

PyCurator allows users to easily query research repositories without the trouble of reading through API documentation. Data curation is now as easy as $ pycurator. Whether you want the ease of clicking some buttons and getting the data or the flexibility of modifying query format, PyCurator provides a simple UI for quickly retrieving data that is built on top of an extensible collection of Web and API scraper classes.

Supported Repositories

PyCurator currently supports the following repositories in the capacities listed. Authentication is only required for Kaggle, though may provide runtime benefits for Dryad as rate-limiting is relaxed.

Repository	Authentication
Dataverse
Dryad	Dryad
Figshare
Kaggle	Kaggle
OpenML
Papers With Code
Zenodo

If there's a repository that you would like to see added to the list, check out the Contributions section.

Installation and use

Installation

Dependencies are provided in the requirements.txt file. It is recommended to create a virtual environment to ensure there is no conflict with the packages in your current work space.

PyCurator requires a Python version >= 3.10.

To run, simply paste the following commands into your terminal

git clone https://github.com/michaelbaluja/PyCurator.git
cd PyCurator
python -m pip install -e .
pycurator

Use

Repository Selection

After following the commands above, you will be met with the landing page, containing licensing, funding, and copyright information. Clicking Continue will bring you to the following page

Parameter Selection

Clicking on one of the repositories will bring up the respective parameters used for querying the API and saving your results. Parameters will vary depending on repository selected.

These parameters are outlined as

Parameter	Description
Save Directory	Location to save results. Defaults to "/data/{repo_name}/{search_term}_{search_type}.json" within PyCurator /data sub-directory.
Search Terms	Search term(s) to query. Terms should be separated with a comma, and multi-word terms should be wrapped in quotes.
Search Types	Type of objects to query.
After all required parameters are provided, the Run button is activated.

Run Page

The run page provides high level status updates in the main window. These include the beginning and end of processes, rate-limiting issues, runtime completion, and saving confirmation. Below are real-time status updates for the specific query being completed as well as a progress bar for the high level task. During tasks that have a fixed duration, such as metadata querying or some web scraping, a fixed-length progress bar will show the progression of output. During tasks that have an indeterminate duration, a cycling task bar will be present to represent continued progress.

At the bottom are the navigation buttons. To avoid unnecessary queries, the Back button is unresponsive during runtime, but is activated after completion. The Stop button is used to interrupt runtime and stop querying. After runtime completion or interruption, the Stop button is replaced by the Exit button, allowing you to safely terminate the program.
