[edit] Large data sources

This is a page for a list of large data sources / data dumps. Some of these sources may have discussion-like structures and would make good candidates for representing in SIOC.

• bulk.resource.org
• Y-Combinator Dataset

[edit] Community sites w/o data dumps

Large community sites can be a source of large amount of SIOC data. List here such sites which would benefit from SIOC-enabling. If they already provide a data dump, list them in the main section (Large Data Sources).
