When a scholar, curator or archivist is researching an artwork, they need provenance, an essential piece of information that can help them evaluate as to whether a source can be trusted. This paper will investigate how to express the provenance of Internet art as linked data. One of the standards that has emerged to describe the provenance of digital data is the W3C PROV. It provides a model which facilitates description of the entities, agents and processes involved in producing data. This generic model has proven to be applicable in various contexts, including the cultural heritage domain [1, 2]. However, its potential to describe the provenance of Internet art is not yet fully explored [3]. This paper demonstrates how the PROV model can be used to describe the provenance of Internet art by applying it to a case study from Rhizome’s ArtBase, an online archive dedicated to preserving works of Internet art. This paper is aimed at digital art conservators, digital curators, Web archivists and art historians.
