Abstract
The convergence of Libraries, Archives and Museums (LAM) has been a topic of much discussion in the \(Digital \, Library \, (DL)\) research field, but their similarities and common points are not yet fully exploited in existing formal models for DL such as the \(Streams, \, Structures, \, Spaces, \, Scenarios, \, Societies \, (\textit{5}S)\) model or the DELOS Reference Model.
On the other hand, Semantic Web and Linked Data technology are nowadays mostly used for interoperability at the data level but they would represent a viable option for building a semantic representation and interoperability at the level of different DL models of themselves.
To this end, we discuss a quite ambitious goal that should be part of the DL agenda that is expressing foundational models of DL by means of ontologies which leverage Semantic Web and Linked Data technologies and which link them to the ontologies currently used for publishing cultural heritage data. This would pave the way for a deeper interoperability among DL systems and lower the barriers between LAMs.
In this paper we exemplify this proposal by focusing on the quality domain which is a fundamental aspect in the DL universe and we show how this part of the DELOS Reference model can be expressed via a \(Resource \, Description \, Framework \, (RDF)\) model ready to be used in a Semantic Web environment for interoperability at the DL model level and not only at the data level.
