What?
• A framework for synchronizing Web resources from a Source to a Destination
8
Web
sync
![Page 21: Interoperability and Its Role In Standardization, Plus A ResourceSync Overview](https://reader033.fdocuments.in/reader033/viewer/2022052822/554bd1e8b4c905706a8b4d10/html5/thumbnails/21.jpg)
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!

arxiv.org mirroring
• 2.4M resources (PDF, metadata, Latex src)
• ~800/day created or updated
• uses homebrew mirroring since 1994 (!)
• look for more general solution to support independent destinations

Wikipedia
• 1.4 updates / sec
• many dependent services reusing Wikipedia content (e.g., DBPedia, Freebase, etc.)
• harvest articles via OAI-PMH, retrieve changes via IRC, download dumps

Design Guidelines
• Sync small websites / repositories (few resources) but also large data collections (millions of resources)
• Support low change frequency (weeks / months) to high change frequency (seconds) sources
• Low adoption barrier!
