An ontology describes a particular domain of knowledge (e.g. bikes, whiskey).
•Establishes controlled vocabulary.
•Models relationships between entities & concepts.
•Built-in rules and datatypes that support reasoning.
Ontologies

Controlled Vocabulary
Terms and definitions are posted online, so they can be shared by many different organizations.

Trust
The largest hurdle to library adoption of Linked Data, though, may not be educational or technological …The sticking point for librarians may be an issue of trust.
- Ross Singer, “Linked Data Now!”
