Tag management for CKAN portals

Project description


Tagmanager offers a graphical interface for removing and merging tags. This is usefull for big open data portals with many contributors, where tags are not always kept consistent.

We offer three modes of tags merging suggestions:

- Strong: show tags that differ only by capitals special characters;
- Medium: show tags that have a Levenshtein edit distance smaller than one;
- Synonym: show tags that are synomyns (only for English)

This extensions is intended to fill the tag managament gap of CKAN. CKAN core offers only a listing of tags, and edition through the specific datasets.

In the future, we plan to offer the creation of relationships between tags, and connection to a central semantic tag server.
