Catálogo Colectivo de la Red de Bibliotecas de los Archivos Estatales y del CIDA (Q61505171) is an online catalog managed by Directorate-General for Fine Arts (Q39021357) (Ministry of Culture of Spain (Q54909112) of Spain). This database hosts a lot of authority data on Spanish published stuff. This proposal is focused in their identifier about publications (I'm aiming periodicals but it includes editions of books too). They have a different identifier on Topics/places/and_so_on. This one would be used immediately in es.wikipedia authority templates, after migrating the already-existing-external-link-template (and probably deleting it afterwards).
