Jina learns two metadata profiles — academic sources stop losing their dates and publishers
The metadata parser was reading only blog/OpenGraph keys, so scholarly articles — whose data hides under Highwire/Dublin-Core/PRISM tags — arrived with no date and a weak publisher, and the operator hand-filled them. Now it detects the source KIND (academic-paper / article / company-landing / web-page), routes to the right parser profile, and resolves every field across all conventions. A Springer article now fills its authors, publisher, and date automatically.
