Runs the IRI expansion algorithm on value, defining terms of local_context on demand.

Used while a context is still being processed, which is why it can recurse into define: expanding a term may require first defining that term, or the prefix of a compact IRI, from the context currently being built. defined guards that recursion against cycles.

document_relative allows a value that is otherwise unresolvable to be resolved against the active context’s base IRI. vocab enables expansion through the vocabulary mapping and selects what to do when that is the only thing that would make the value expand; None disables it entirely.

A value that resolves to nothing usable is returned as an invalid identifier and reported through the warning handler, rather than failing.

Errors

Returns an error when a term definition needed for the expansion is invalid, or when loading a remote context fails.
