Internet-based art is deeply embedded in the online behaviours, customs and traditions that are constantly emerging through user interaction and engagement. As such, user experience should be considered a fundamental aspect of the artwork in need of considered documentation. This paper provides a historical overview of Internet-based art, that presents the broader socio-cultural aspects of Internet-based art, as experienced by the user. This paper argues that Internet-based art requires the same conservation considerations as more accepted aspects of time-based media art documentation: source-code analysis, materials and equipment lists, variability and artists' intent. By documenting user experience, it enables opportunities to navigate the culturally-embedded principles of Internet culture and contemporary technological standards that may be lost if preservation strategies utilise a more material/code specific preservation strategy. Highlighting experience as a necessary pillar of the identity of Internet-based art, in conjunction with other widely accepted aspects of time-based media art documentation approaches, allows for a richer picture and understanding of defining qualities of works, whilst providing further evidentiary activation into preservation approaches.
