This document summarizes a presentation about CKAN, an open source data catalog. CKAN allows users to publish, edit, and manage metadata for datasets. It provides features for searching, visualizing, and sharing data. CKAN supports standards like DCAT and can integrate with other catalogs through harvesting of metadata. The presentation covered CKAN's capabilities for publishing, authoring, searching, displaying data, and administrative functions.
