See minutes online for a more detailed record of the discussions. (The headers below link into the relevant sections of the minutes.)
Jake Archibald, one of the editors of the Service Workers Draft, was a guest of the meeting, and gave a short overview of Service Workers.
(The reason of this discussion is because Service Workers have been identified as one of the possible means to create a PWP Architecture.)
Service workers can also be used to unpack content on the fly, whether the packed content is in some ZIP format or other packaging format (the issue around the streaming ability of ZIP and other formats came up during the discussion).
There were some discussion about the availability of SW in browsers (is true for Chrome and Firefox, Microsoft Edge is in the process of development, nothing is known of Safari). There are also plans to create more tutorials and introductory texts for the specification.
Subsequent discussions on the meeting concentrated on the experience using Service Workers. Dave Cramer, from Hachette, has already played with this with a good first impression. The Readium consortium has also tried using it, and Daniel Wreck, from the consortium, shared his experiences and questions. The Readium proof-of-concept implementation is able to handle an EPUB content that is exploded on the web server or is able to do some ZIP unpacking (the current implementation does not do caching, only fetch intercepts). There were issues about same-origin constraints, usage of HTTPS as opposed to HTTP.
The PF Working group has created a document analyzing the various proposed content description techniques for accessibility purposes (i.e., usage of
<detail>, etc. That document aimed describing the various needs of the publishing industry; that was now reviewed by Deborah and Mia, primarily, with comments from others. The document is now ‘back’ to the PF Working Group.
