I’d like to thank the community for providing valuable feedback on the SSE spec through the FEED-TECH mailing list. We’re learning a lot from you, and appreciate your questions, comments, suggestions. Based on the feedback we’ve received and some discoveries we’ve made building sample code, we’ve released a revision of the SSE Specification (version 0.91). You can track the specific changes we’ve made to this revision of the spec in the change history, and we’ll be archiving all previous versions of the spec, at least for duration of the review process. I’d like to highlight a few changes we’ve incorporated that are attributable to the community review process:
- Charles Cook pointed out via the FEED-TECH mailing list that there are cases where independent replication of hierarchical items could result in cycles (in which two items each point to the other as a parent). To address that possibility, we’ve added a deterministic algorithm to break cycles.
- Yc J suggested that we add a spec version number to the format (to deal with future compatibility). Makes perfect sense, and we’ve added it in this rev.
Things Not Yet Addressed in this Version:
- Date Format: We’re still contemplating how best to properly define the date format. As Danny Ayers, Sam Ruby, David Powell and others have pointed out, there are better date formats than RFC 822. For example, we’re trying to figure out how to support dc:date. (Though we’ve at least fixed the examples and have stated explicitly that valid dates are RFC 822 with 4-digit years [which is the format for RSS 2.0]).
Also, I’d like to highlight some examples of “SSE in the wild” that have recently emerged. It’s great to see early adopters like Matt Terenzio take the initiative with projects like SkinnyFarm. If you have used SSE in a project and would like to share your experience with the community, please let us know via the mailing list.
