Designers of networked knowledge organization systems often follow a service-oriented design strategy, assuming an organizational model where one party outsources clearly delineated business processes to another party. But the logic of outsourcing is a poor fit for some knowledge organization practices. When knowledge organization is understood as a process of exchange among peers, a sharing-oriented design strategy makes more sense. As an example of a sharing-oriented strategy for designing NKOS, we describe the design of the PeriodO period gazetteer. We analyze the PeriodO data model, its representation using JSON-LD, and the management of changes to the PeriodO dataset. We conclude by discussing why a sharing-oriented design strategy is appropriate for organizing scholarly knowledge.
