While HIPPOLYTOS exploits explicit metadata, semantic annotations and ontological background knowledge for making structured data easier findable, KOIOS realizes a schema-agnostic search approach together with a faceted-search GUI. In this article, the main emphasis is laid on HIPPOLYTOS.Text/Conference Paper
