Europeana's corelib resolves rights URIs tolerantly: after lower-casing and https-to-http rewriting, even 'exact' mode is a substring test (to accept version or language suffixes), and loose mode matches short patterns and, by the code's own comment, malformed strings. A test fixture lists legacy europeana.eu/rights values in the millions (rr-f about 8.6 million) at an undated snapshot; this is a fixture, not a published statistic.
