  The formal representation of cultural metadata has always been a challenge,
considering both the heterogeneity of cultural objects and the need to document
the interpretive act exercised by experts. This article provides an overview of
the revalorization of the digital collection Mythologiae in Linked Open Data
format. The research aims to explore the data of a collection of artworks
(Mythologiae) by promoting the potential of the Semantic Web, focusing
particularly on the formal representation of the association of cultural
objects with literary sources, as realized by experts, also documenting their
interpretations. The workflow consisted of defining the data model, cleaning
and disambiguating the data, converting it (from tabular structure to graph),
and conducting testing activities (particularly expert domain review of the
dataset through competency questions and data visualizations). The result is
the mythLOD platform, which presents the dataset and detailed research
documentation. Additionally, the platform hosts two data visualization spaces
(the online catalogue and a data storytelling experiment on the case study of
the Aeneid) that enrich the project documentation as user-friendly test units
for the dataset and constitute an additional project documentation tool and
exploration of the collection.
