Interoperability and Its Role In Standardization, Plus A ResourceSync Overview
3 likes4,300 views
This document summarizes Peter Murray's presentation on interoperability and its role in standardization. The presentation covered four levels of interoperability: technical, syntactic, semantic, and organizational. It also discussed the ResourceSync specification, which provides a framework for synchronizing web resources between a source and destination using sitemaps. The specification builds on existing sitemap standards and is currently in beta with the goal of finalizing version 1.0 in fall 2013. Implementation tools are being developed and public feedback is being solicited to improve the specification.

- 21. NISO Update,American Library Association, 30-Jun-2013 Why? • rsync: filesystem sync, but not Web • OAI-PMH: metadata, but not resources • Web-DAV: extends HTTP, requires server installation at source • ... 9 … because lots of projects and services are doing synchronization but rely on ad-hoc solutions!
