OR2023 provides an opportunity to explore and reflect on the ways repositories enable discoverability and interoperability of information and data within the structured web of data. How can we better utilize repositories for machine interoperability? How can we develop the capacity of institutions to implement sustainable open repositories to improve data equity worldwide? In doing so the OR2023 conference will focus on the practices of the international repositories community to develop and implement the standards, frameworks, architectures, and methodologies for open repositories to serve as knowledge representation databases for the structured web of data.
