is Contribution to the DCO
The Research Data Alliance (RDA) - Data Type Registry (DTR) working group addressed a core issue of data interoperability: to parse, understand, and potentially reuse data retrieved from others. The RDA - Persistent Identifier Information Types (PIT) working group addressed the essential types of information associated with persistent identifiers (PID). The Deep Carbon Observatory (DCO; http://deepcarbon.net) Data Portal enables centrally-managed digital object identification, object registration, metadata management and knowledge graph curation. DCO anticipated a large number of digital object registrations, and therefore needed an appropriate mechanism to curate and reuse the registered information.
