This article presents concepts like "the Archive" and "the Repertoire" (D. Taylor), obligatory passage points (M. Callon), "boundary objects" (S. Star) and the metaphor of the "Blue Arsenal" as useful tools to explore the impact of the Basic Texts of the 2003 UNESCO Convention for the Safeguarding of the Intangible Cultural Heritage. It zooms in on the connection between Operational Directives 108 and 109. Furthermore, new European heritage policy instruments are introduced, next to reflections on the debates on the operational definition of what a museum is according to ICOM, and why the 2003 UNESCO Convention's paradigm should not be ignored in this debate.
