The changes to the Toolkit are a necessary evolution away from the slowly devolving MARC21 data model toward the RDA data model. But the audience doesn&#8217;t, can&#8217;t, easily see that distinction, and the \u2018questions\u2019 swirl around expressions of discomfort with the changes that reflect a lack of understanding of the broadening disconnect between the Toolkit and the Registry, and between RDA and MARC21.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This cognitive dissonance <\/span><i><span style=\"font-weight: 400;\">must<\/span><\/i><span style=\"font-weight: 400;\">\u00a0be addressed by the RSC and its representatives at every future opportunity when discussing the rationale for both the alignment of the RDA data model with IFLA LRM, and the alignment of the RDA content model in the Toolkit with the RDA data model.
