Recent changes
September 15, 2008: Released version 1.0.1. This version incorporates the following changes:
- Added the following constraints in section 2.1.5 for time values:
- Times MUST be expressed in whole seconds only; fractional second values MUST NOT be present.
- Times MUST be given in the UTC timezone, and end in “Z”, without a timezone offset.
- Removed the old section 2.1.6 which described how time values must be compared.
- Removed the second note in the definition of sx:sync/@id in section 2.4 which stated that two entries in the same feed with the same atom:id should be considered different sync items.
- Added a new step 3.2.4 to the update algorithm. Without this new step, an endpoint could briefly get into an inconsistent state. This new step eliminates that possibility.
September 15, 2008: Added the implementation notes document.
September 15, 2008: Added the FeedSync for Collections draft specification.
December 19, 2007: Updated Section 6 to note that the FeedSync specification is now covered under the Microsoft Open Specification Promise. More details are available here.
