If used up to their most important recommendations, RDA guidelines lead to a semantic web oriented catalog. Both authority and bibliographic records require to be curated, especially under the point of view of persistent identifiers, connecting entities to relevant external resources, thus boosting the navigability of the retrieved information and finally of the whole catalog. To dramatically improve these goals, also established records need to be provided with links, URIs, or persistent identifiers. An automatic approach was studied and applied in two phases to authority records of a Koha catalog. A new tool was created and added to the detailed display of a bibliographic record in order to show valuable information for each agent having a responsibility.
