Linked data is an amazing yet elusive idea. It extends the web by providing a means to identify and refer to specific entities or concepts (e.g. Colin McCahon, Timaru, modern painters) and a way to describe how those things are related (e.g. ‘Colin McCahon was born in Timaru’, ‘Colin McCahon was a modern painter’). Together the entities, concepts and relationships constitute a set of assertions about how we think the world is, which can be queried, analysed, extended, shared and visualised.
However, institutions structure data in diverse ways. For example, the data schema and conventions used by Te Papa differ from those used by Alexander Turnbull Library. Such diversity complicates the task of forging digital links between entities and items. This talk assumes that it is difficult and expensive to align our existing descriptive practices and metadata formats across institutions and instead proposes a methodology for building bridges between collections that supply context and translate for the machines – small pieces loosely joined over the one true ontology.
Chris McDowall is the manager of DigitalNZ systems. He looks after machines, metadata and people.
