IAB and W3C gratefully acknowledge the STREWS project for hosting this workshop

… and Telefónica Digital for providing the workshop facilities.

This is the agenda for the STRINT Workshop .

On this page:


Sessions will have at most 50% presentation material. Workshop chairs will impose strict timing on session moderators who will do the same to you! Interrupting with questions and comments is welcome but hogging the microphone will be loudly countered by the workshop and session chairs. The goal is moderated discussion and progress and not showing off slideware. Only the session moderators or presenter gets to project slides – please don't ask to project yours, because we don't have time.

There will be no individual presentations.

Each session will be moderated and has a member of the Technical Program Committee (TPC) as shepherd. For some, the moderator will present, for others, the TPC have asked someone else to present as well. If you're interested in a particular session feel free to contact any of the above and say what you think needs discussing, or bring it up on the attendee mailing list.

Attendees are assumed to have read the submissions about which they care. To help with that, please read, and contribute an abstract of your paper, to this etherpad. Presentations are to refresh memory or draw out salient points for discussion, and will not be introductory or tutorial in nature.

Laptop use is expected. We'd rather you didn't just do email or hang about on some social network, but we can't stop you. You can take photographs, but they'll be boring. The meeting may be streamed and recorded. By being there you agree to that.

It is recommended to join the chat room: IRC channel #strint on irc.w3.org. (You may see two 'bots on the channel: Zakim and RRSAgent.) For off-the-record comments (not logged), please use “/me” (e.g.: /me needs coffee). There is also a Web interface to IRC.

Streaming audio: http://nagasaki.bogus.com:8000/stream10

Invitees will be subscribed to the workshop attendees discussion list, (strint-attendees@lists.i1b.org, public archive) and are expected to begin the discussion before the workshop.

Workshop goals

The STRINT workshop starts from the position that Pervasive Monitoring (PM) is an attack. While some dissenting voices are expected and need to be heard, that is the baseline assumption for the workshop, and our high-level goal is to provide some more consideration of that and how it ought affect future work within the IETF and W3C.

At the next level down the goals of the STRINT workshop are to:


Details will likely evolve as a result of attendee-list discussion between now and the workshop. Note that it is not possible to have break-outs on Friday. Saturday break-outs will be planned during breaks Friday and overnight. Each session has some TPC member(s) as a shepherd who are arranging materials and presenters (see above).
