				<h2>Save and find <strong>semantic artefacts</strong></h2>
				<p>The primary mission of an OntoPortal installation is to host and serve ontologies and semantic artefacts. The portals accept resources in multiple knowledge representation languages: OWL, RDFS, SKOS, OBO and UMLS-RRF.</p>
				<p>Ontologies are semantically described with rich metadata (partially extracted from the source files), and a browsing user interface allows to quickly identify, with faceted search, the ontologies of interest based on their metadata.</p>
