Collection Synchronization for WebDAV (RFC 6578)

RFC 6578 (2012) adds delta synchronization to WebDAV — a server returns a sync-token with a collection, and a later sync-collection report with that token returns only the members that were added, changed or removed since. It is the mechanism CalDAV and CardDAV clients use to stay current without re-listing, and the standards-track precedent for every cursor-based change feed in the drive APIs that followed.

Providers that carry WebDAV Collection Synchronization 0

No provider in the catalog carries this standard as a tag yet. That is a statement about the catalog's tagging, not about adoption: a provider that implements WebDAV Collection Synchronization and says so in its APIs.json profile appears here on the next build. Add or correct a listing.
