Name, things, places: towards a semantic, sustainable, usable integration?

In the nowadays world characterized by complexity, the digital systems for archival and bibliographic description are, especially in Italy, a faithful mirror of too many horizontal (among bodies with national functions) and vertical (among central and peripheral levels) complications. The integration of data sets conceived according to the up-to-date conceptual domain models would simplify the dynamics of representation, improve user experiences, and optimize the environmental costs of computing infrastructures. The concepts to be shared should relate to agents (individual or collective), places, and chronological data, deepening on how to address the more complex issues opened by things. This paper introduces three possible scenarios of semantic cooperation between archivists and librarians, not necessarily alternative: activating a conceptual matching through common entities, relying on a neutral semantic data infrastructure such as Wikidata, or, finally, developing a transversal core ontology. Hoping that disciplinary boundaries will not impede cooperation, two types of impediments must be considered: the organizational one (bottom-up, top-down, or a virtuous synergy between the two organizational models?) and the crucial issue of offering easy-to-use interfaces to end-users, not only constituted by software agents.
