This repository includes tags and tag descriptions from StackExchange sites converted to knowledge organization systems in SKOS format.
Tags in StackExchange
StackExchange is a network of Questions & Answers websites. Questions in each website are collaboratively indexed by social tagging in a set-model (each question is assigned a set of tags that users of the community can edit). StackExchange tags can be described with a short excerpt, a more detailed text, and they may have synonyms. Tags can be edited by the community. The content of all StackExhange websites, including tags and tag descriptions is licensed under CC-BY-SA.

From Tags to SKOS
Although Jeff Atwood was against hierarchical links between tags, these relations are supported if given in a tag wiki with Unicode upwards/downwards arrows (↑/↓). Mappings to other knowledge organization systems are also added.
