Hi, This Chromium work in W3C looks interesting and useful - read on. Cheers, - Ira ---------- Forwarded message ---------- From: Jeffrey Yasskin <jyasskin@chromium.org> Date: Thu, Jun 15, 2017 at 3:09 PM Subject: [dispatch] A packaging format for the web To: dispatch@ietf.org Hello Dispatch, TL;DR: We're bringing the work at https://github.com/WICG/webpackage to the IETF. People would like to use content offline and in other situations where there isn’t a direct connection to the server where the content originates. However, it's difficult to distribute and verify the authenticity of applications and content without a connection to the network. The W3C has addressed running applications offline with Service Workers (https://www.w3.org/TR/service-workers-1/), but not the problem of distribution. * People with expensive or intermittent internet connections are used to sharing files via P2P links and shared SD cards. They should be able to install web applications they received this way. Installing a web application requires a TLS-type guarantee that it came from and can use data owned by a particular origin. * Verification of the origin of the content isn't always necessary. For example, users currently share screenshots and MHTML documents with their peers, with no guarantee that the shared content is authentic. However, these formats have low fidelity (screenshots) and/or aren't interoperable (MHTML). We'd like an interoperable format that lets both publishers and readers package such content for use in an untrusted mode. * CDNs want to re-publish other origins' content so readers can access it more quickly or more privately. Currently, to attribute that content to the original origin, they need the full ability to publish arbitrary content under that origin's name. There should be a way to let them attribute only the exact content that the original origin published. We think a packaging format can help satisfy these use cases. This format likely also has other uses, and we should try to support such use cases as long as they don't compromise the offline use cases. For example, packages may help optimize transferring online content or let third-parties assert properties of the package via cross-signatures. The Chromium project has started work on this sort of packaging format within the W3C's WICG, at https://github.com/WICG/webpackage. We have a list of use cases, some goals and explicit non-goals, and a draft for the format itself. We believe the IETF is the ideal place to standardize the format, and in parallel we'll specify within the W3C how browsers should load it. I'll be writing an initial internet-draft in the next couple weeks, in time to bring it to IETF 99. We'd appreciate being directed to the appropriate place within the IETF to do this work. Thanks, Jeffrey Yasskin P.S. I'll be on vacation from June 16-23; I'll reply intermittently during that time but mostly once I get back. _______________________________________________ dispatch mailing list dispatch@ietf.org https://www.ietf.org/mailman/listinfo/dispatch
