Scope of the Spec Spec does not include an implementation as there is proprietary issues
in the protocol used by CAN and MOST data networks
What is the contentious vehicle data that should NOT be exposed in this first version of the draft spec?
What about reading vs writing vehicle data?
Discussion
Food for thought: Which spec do we start from or do we start it from scratch or use a
combination? What about starting with OBDII since it’s a gov’t regulation?

Roles and Responsibilities
• All participants are encouraged to• Attend group’s formal meetings• Follow and participate in mailing list (+IRC) discussions – all technical
discussions should happen on the group’s mailing list(s)• Review draft proposals, propose changes, fix spec bugs
• Editor’s responsibilities• Edits the spec based on group consensus• Follows group’s technical discussion and integrate proposed changes• Makes sure someone in the group responds to comments submitted to
the spec(s)
• Practicalities• Each spec needs at least one active editor• The group agrees on the work mode such as “commit-then-review” vs.
“review-then-commit” together with the editor(s)
INTEL CONFIDENTIAL11 SSG System Software Division
Process1. Describe the problem to solve, list use cases
2. List requirements for each use case
3. Share the use cases and requirements with the group, adjust based on feedback from the group
4. Study existing proposals, come up with new proposals, keep the proposal as simple as possible and defer “nice to haves” for later
5. Evaluate how well the proposals address the use cases and meet the requirements, choose/create/merge a proposal that the group thinks is the best fit
6. Write draft spec, tests, publish spec snapshot(s)
Finally: “Some (but not all) Business Group Specifications are expected to serve as input to a Working Group.”

Top-level Organization of a Spec
• Introduction – an overview of the technology
• Conformance – how conformance is determined in the spec• E.g. “Everything in this specification is normative except for diagrams,
examples, notes and sections marked non-normative. […] A user agent must also be a conforming implementation of DOM4.”
• Terminology – definitions of terms used• E.g. “The term user credentials for the purposes of this specification means
cookies, HTTP authentication, and client-side SSL certificates.”
• Content• Normative – requirements and definitions• Informative – everything else
• References
• Acknowledgements
Specs should follow the patterns and style established by other specs.
INTEL CONFIDENTIAL13 SSG System Software Division
Top-level Organization of a Spec: Content (detailed)
• Normative• Interface definition – Web APIs are defined using Web IDL, e.g.:
• Requirements and definitions• “The XMLHttpRequest(options) constructor MUST run these steps”
• Use RFC2119 terms must, should, may• Normative must statements should be testable
• Informative• Everything that is not normative, e.g. use cases, code examples, diagrams• Must not use RFC2119 keywords, use “can” or “is” instead
[Constructor(optional XMLHttpRequestOptions options)]interface XMLHttpRequest : XMLHttpRequestEventTarget { // event handler attribute EventHandler onreadystatechange; // …};

Next Steps Looking beyond vehicle data, what’s to tackle next?
Recommend looking at all of the papers and presentations from the W3C Automotive and Web Workshop last fall: http://www.w3.org/2012/08/web-and-automotive/summary.html UI Constraints (driver safety, distraction and adjusting the GUI) Application Security and Safety (handling different input controls) Navigation (see W3C Geolocation API) Voice Recognition (see W3C Web Speech API) Audio Policy Management (addressing policy and management of multiple sinks and sources)
List of potential areas (15 of them) to focus on next: http://www.w3.org/community/autowebplatform/wiki/Main_Page/CollectionOfApis
Should we break into task forces to research various topics? Example model we could follow: http://www.w3.org/2011/webtv/wiki/TF_handling_rule Task force area specific Wiki pages:
http://www.w3.org/community/autowebplatform/wiki/Main_Page#Sub_Task_Teams
Conf Calls How often should we have them? Every 2 weeks, every month? Next F2F? If so, where? When?
Decisions should be discussed and made online and through the email distro list
