    pip install arche

Arche (pronounced *Arkey*) helps to verify scraped data using set of defined rules, for example:

  * Validation with [JSON schema](https://json-schema.org/)

  * Coverage (items, fields, categorical data, including booleans and enums)

  * Duplicates

  * Garbage symbols

  * Comparison of two jobs

  

_We use it in Scrapinghub, among the other tools, to ensure quality of scraped data_

## Installation

Arche requires [Jupyter](https://jupyter.org/install) environment, supporting both [JupyterLab](https://github.com/jupyterlab/jupyterlab#installation) and [Notebook](https://github.com/jupyter/notebook) UI

For JupyterLab, you will need to properly install [plotly extensions](https://github.com/plotly/plotly.py#jupyterlab-support-python-35)

Then just `pip install arche`

## Why

To check the quality of scraped data continuously. For example, if you scraped a website, a typical approach would be to validate the data with Arche. You can also create a schema and then set up [Spidermon](https://spidermon.readthedocs.io/en/latest/item-validation.html#with-json-schema)

## Developer Setup

	pipenv install --dev

	pipenv shell

	tox
