sabre-dav

sabre/dav & Baikal A popular CalDAV/CardDAV/WebDAV implementation in PHP, integrated into pretty much any PHP-based project that requires these features and sometimes even in non-PHP projects that simply don't have a solid extendable implementation. sabre/dav is the library, baikal is a management application on top of it. This months goal: - Update baikal to use Silex instead of a proprietary framework. Next months goal: - A new design for Baikal Needed skills: - Intermediate PHP developer.

Full disclosure: I contributed to the remoteStorage specification [0]. Instead of (or in addition to) considering remoteStorage, one could also go back to "normal" WebDAV, if such a thing exists, and completely forget about the CalDAV/CardDAV servers. I'd say WebDAV is more mature, it has litmus[1] for testing implementations. remoteStorage has as far as I know only one production instance running at 5apps [2]. The benefits of using the RS protocol are mostly due to the CORS headers (which could be implemented easily for WebDAV) and the use of OAuth/Bearer, for which a PR exists for SabreDAV [3]. One thing missing from WebDAV is the (implicit) mapping of OAuth scopes to ACLs, which should not be too difficult to implement... The discovery, by depending on Webfinger, is also not one of my favorites. I'd prefer something like OAuth authoriz
