Data Comparison

ckanext-datacomparison is a CKAN plugin replacing the original Data Explorer. This extension is inspired by the Data Explorer React (https://github.com/datopian/ckanext-dataexplorer-react).

The main feature of ckanext-datacomparison is the capability to compare data across resources. The visualizations are powered by plotly.js.

The following view plugins are part of ckanext-datacomparison:

• datacomparison_view the view plugin providing the feature of comparing data across resources
• datacomparison_explorer_view a view plugin acting like the Data Explorer using the same code basis as the comparison view

Note

The current version of datacomparison_explorer_view uses the first column of each resource for merging the data.

Afterward, add datacomparison_view and/or datacomparison_explorer_view to the plugins in your ckan.ini.
