ResourceSync: Web-Based Resource Synchronization. Also for Data.
Herbert Van de Sompel, Digital Library Researcher, Los Alamos National Laboratory, and Co-chair of NISO’s ResourceSync Working Group
Web applications frequently leverage resources made available by remote Web servers. As resources are created, updated, or deleted these applications face challenges to remain in lockstep with the server’s change dynamics. Several approaches exist to help meet this challenge for use cases where “good enough” synchronization is acceptable. But when strict resource coverage or low synchronization latency is required, commonly accepted Web-based solutions remain elusive. Motivated by the need to synchronize resources for applications in the realm of cultural heritage and research communication, the National Information Standards Organization (NISO) and the Open Archives Initiative (OAI) have launched the ResourceSync project that aims at designing an approach for resource synchronization that is aligned with the web architecture and that has a fair chance of adoption by different communities. The presentation will discuss some motivating use cases and will provide a perspective on the resource synchronization problem that results from ResourceSync project discussions. It will provide an overview of the ongoing thinking regarding an approach to address the challenges and will pay special attention to aspects that are relevant for the synchronization of data.
