HTML Working Group Issues

• Tracker is a HTML Working Group issue, action and resolution tracking tool.

• Teleconferences are typically used to facilitate issue coordination with minutes announced via the announce mailing list.

• Surveys are a working group tool to aid information gathering and if needed decision making. For more information visit decision history.

• A number of mailing lists are used for HTML Working Group business, proposals and issues.

• Several task forces exist for specialized issues and work.

Tracker Definitions

• ISSUE = A topic of concern or a problem. (An issue defines a problem.)
• ACTION = The process of doing something in order to resolve or help resolve an ISSUE. (An ACTION generates a potential resolution to an ISSUE, or helps solve it e.g. by gathering more information.)

Tracker Issue State Definitions

• RAISED = A working group member suggests this is worth a WG discussion and potentially a decision, but to date no concrete proposal has been created that enjoys a consensus of at least one.

• OPEN = At least one concrete proposal has been made resolving this issue, but one on which consensus has either not been evaluated, or has not yet been reached; a working group member is assigned an ACTION to follow up (similar to ASSIGNED).

• PENDINGREVIEW = An Editor has reviewed arguments and edited spec to taste, or the WG chairs have evaluated the level of consensus and identified one or more proposals that would resolve the issue. In the case where multiple proposals are identified, the Editors may make the determination as to which one to incorporate.

• POSTPONED = The WG has decided the issue will not be addressed at this time due to engineering constraints, cost-effectiveness, or the inability of the issue to be address in the time defined by our charter. To be investigated during the next chartering period.

• CLOSED = The chairs believe either the WG has resolved the issue (via spec editing) or the issue has been withdrawn. Only the chairs should move issues to 'closed'. Typically moving issues from PENDINGREVIEW to CLOSED will involve review in the weekly telecon.

Tracker Action State Definitions

• OPEN = A working group member has been assigned this ACTION, and has clear steps to follow up (an action cannot be created without assigning to someone).

• PENDINGREVIEW = The person to whom the action was assigned has further information or a recommendation, and wishes the WG and chairs to review it. This may also be used to flag a status update, but then move back to OPEN (e.g., an assignee wants to get on the agenda for the weekly telecon to give a status update, but then still has more to do to complete the action.

• CLOSED = The chairs believe either the action was withdrawn or it has been completed. Only the chairs should move actions to 'closed'. Typically moving actions from PENDINGREVIEW to CLOSED will involve review in the weekly telecon.

Issue Resolution Related Policies

• W3C Definition of Concensus.

Issue Reference

The list below is a collection of research concerning issues raised on the public-html@w3.org mailing list (archive). Please follow the issue template when creating new reference pages, including adding links to all the related e-mails in the discussion. Be sure to document issues in a way that the editors will pay attention to them.

Solution proposals

Since solutions are sometimes designed to address multiple problems, it will be useful to create hyperlinked pages describing solutions and proposed solutions that link to problem statement/ use-cases pages. Likewise, the use-case pages should link to proposed solution pages and the HTML5 draft and elsewhere.

General document enhancements

• Much ado about Q:Proposal to eliminate the Q / BLOCKQUOTE distinction and associating quotations with sources.

• Proposal for eliminating authoring distinctions between block and non-block semantics

Quotations

• Proposal for associating attributions, citations, quotations and references

• New markup attribute on Q and BLOCKQUOTE: "marks"

Key binding mechanism

• A proposal to provide a flexible, international, device independent and cascading key binding mechanism for HTML documents.

Authoring definitions structurally

• Defining terms, variables, proper nouns, and abbreviations

Form/WebApp enhancements

Accessibility enhancements

Use-cases / Problem statements for changes in the draft

The HTML 5 differences from HTML 4 draft enumerates a number of attributes and elements that are different between the two specifications, but it gives little by way of rationale for the changes. As rationale for changes emerges (see Proposed Design Principles, Rationales Gathering, and public-html) please update the following index of changed elements and attributes.

Justification for Adding Elements
