The development of linked data vocabularies and infrastructure remains primarily project-based. While such experiments and short-term initiatives move the field forward, they often overlook the demands of ongoing maintenance and sustainability. Because linked data infrastructure and vocabularies are fundamentally interdependent, the deprecation or disappearance of one project cascades to damage other vocabularies and systems which had incorporated it into their design. Such losses undermine the development of a robust semantic web, particularly harming those who don’t have the expertise or infrastructure to adapt quickly. In this chapter, we review several key cases of loss and rescue and propose maintenance and sustainability as core ethical responsibilities in linked data development.
