dadresse

Dadresse is a term used in discussions of digital information architecture to describe a stable, persistent address for a resource that remains valid across changes in location or metadata. The concept is usually treated as a high-level abstraction rather than a specific protocol.

The word appears to be a portmanteau of data and adresse (French for address) or a stylized form of address. It is not part of formal standards and has no single official definition.

A dadresse aims to separate the identity of a resource from its current location. In theory, accessing a dadresse should resolve to the resource even if its storage or URL changes, via a resolver or indirection layer.

In practice, the term is used in academic debates and by some technology startups to illustrate ideas about persisting references. It is often discussed alongside established concepts such as DOIs, URNs, and persistent identifiers, and is not universally adopted.

Related concepts include persistent identifiers, DOIs, URNs, URLs, and resource resolvers.
