Since April 2016, the Art Libraries Society of North America's Cataloging Advisory Committee (CAC) and the RBMS Bibliographic Standards Committee (BSC) have collaborated with the Andrew W. Mellon Foundation funded Linked Data for Production project on the Art and Rare Materials BIBFRAME Ontology Extension (ARM). BIBFRAME leaves some areas underdefined that need to be expanded by specialized communities. More specifically, ARM facilitates the descriptive needs of the art and rare materials communities in areas such as exhibitions, materials, measurements, physical condition and much more. Between April 2016 and February 2018, work focused on modeling. In February 2018, our focus shifted to development of SHACL application profiles for Art resources and a Rare Monographs, which we are using to define forms and display for the cataloging environment in VitroLib, an RDF-based, ontology agnostic cataloging tool being developed as part of the Linked Data for Libraries - Labs project that was discussed at DCMI 2017. Since these application profiles are being implemented in VitroLib, catalogers will be able to test the ARM modeling in a real-world environment, providing feedback to the project for potential future development. This presentation will provide an overview of select ARM modeling components, detail the process of creating and defining SHACL application profiles for ARM, and discuss challenges and opportunities for implementing these profiles in VitroLib. Further, we will discuss our strategy for low-threshold hosting of the ontology and administrative questions regarding long-term maintenance of this BIBFRAME extension
