'''This page violates several aspects of the microformats [[process]].  In particular: failure to document examples, failure to document previous formats (e.g. VTODO in [[RFC2445]]), premature naming.  Please read [[process]] and join the microformats-new mailing list before proceeding any further.'''

<h1>Tasks - Compound Microformat</h1>
''Initial draft''


''This is just an initial draft''
This wiki page outlines the overall effort to develop a task microformat. We intend to document [[task-examples|current examples of tasks]] on the web today, their implicit/explicit schemas, and current task/to-do formats, with the intent of deriving a task microformat from that research.


<h2>Problem</h2>
__TOC__
Currently there is no extensible HTML format for creating/storing/sharing project TASKS. Tasks and ToDo items are typically handled by proprietary desktop software clients like mail programs and calendar applications but cannot be shared across platforms or between applications.

* [[User:WalterStevenson|Walter Stevenson]]: I release all my contributions to this specification into the public domain and I encourage the other authors to do so as well.
** When all authors/editors have done so, we can remove the MicroFormatCopyrightStatement template reference and replace it with the MicroFormatPublicDomainContributionStatement.


<h2>Previous Formats</h2>
== Semantic XHTML Design Principles ==
The Task Microformat may be based loosely on elements found in the VTODO spec. [http://en.wikipedia.org/wiki/ICalendar#To-do_.28VTODO.29 VTODO] is part of the [http://www.ietf.org/rfc/rfc2445.txt RFC2445 iCalendar spec] used for describing task items. VTODO is fairly straight-forward, as it doesn't contain any nested entities, and has a fairly small list of properties.  Most of these it shares with VEVENT, suggesting a Task Microformat be modeled on hevent in [[hcalendar]], and the ground assumption is that htodo should work just like hevent with respect to these properties.  The shared properties in this case might include:
{{semantic-xhtml-design-principles}}


''class, created, description, dtstamp, dtstart, geo, last-mod, location, organizer, priority, recurid, seq, statusm summary, uid, url, duration, attach, attendee, categories, comment, contact, exdate, exrule, rstatus, related, resources, rdate, rrule, x-prop''


The unique properties of the existing VTODO format are:
== Purpose ==
'''The Challenge''': Currently there is no extensible hypertext format for creating, exporting, and sharing project TASKS. Tasks and ToDo items are typically handled by proprietary desktop software clients like mail programs and calendar applications that are not:  


* '''completed''' The date/time the todo was completed
* open to the web development community
* '''due''' The date/time this todo is due
* extensible for future usage scenarios
* '''percent''' Integer from 0-100, completion status
* interoperable between applications
* portable between systems
* accessible for persons with disabilities


As the data types for '''completed''' and '''due''' are the same as, e.g., '''dtstart''', then the usage should be the same.  For example,


&lt;abbr class="due" title="2007-01-01T13:10:05.0Z"&gt;January 1, 2007&lt;/abbr&gt;
'''The Vision''': To create a fully-functional Task Microformat for 1) open use in home-grown clients, widgets and applications and 2) adopted for integration with existing software applications such as Microsoft Outlook, Mozilla Thunderbird, Mac Mail, and other popular programs.

Tasks - Compound Microformat

Initial draft

This wiki page outlines the overall effort to develop a task microformat. We intend to document current examples of tasks on the web today, their implicit/explicit schemas, and current task/to-do formats, with the intent of deriving a task microformat from that research.

Semantic XHTML Design Principles

Note: the Semantic XHTML Design Principles were written primarily within the context of developing hCard and hCalendar, thus it may be easier to understand these principles in the context of the hCard design methodology (i.e. read that first). Tantek

XHTML is built on XML, and thus XHTML based formats can be used not only for convenient display presentation, but also for general purpose data exchange. In many ways, XHTML based formats exemplify the best of both HTML and XML worlds. However, when building XHTML based formats, it helps to have a guiding set of principles.

  1. Reuse the schema (names, objects, properties, values, types, hierarchies, constraints) as much as possible from pre-existing, established, well-supported standards by reference. Avoid restating constraints expressed in the source standard. Informative mentions are ok.
    1. For types with multiple components, use nested elements with class names equivalent to the names of the components.
    2. Plural components are made singular, and thus multiple nested elements are used to represent multiple text values that are comma-delimited.
  2. Use the most accurately precise semantic XHTML building block for each object etc.
  3. Otherwise use a generic structural element (e.g. <span> or <div>), or the appropriate contextual element (e.g. an <li> inside a <ul> or <ol>).
  4. Use class names based on names from the original schema, unless the semantic XHTML building block precisely represents that part of the original schema. If names in the source schema are case-insensitive, then use an all lowercase equivalent. Components names implicit in prose (rather than explicit in the defined schema) should also use lowercase equivalents for ease of use. Spaces in component names become dash '-' characters.
  5. Finally, if the format of the data according to the original schema is too long and/or not human-friendly, use <abbr> instead of a generic structural element, and place the literal data into the 'title' attribute (where abbr expansions go), and the more brief and human readable equivalent into the element itself. Further informative explanation of this use of <abbr>: Human vs. ISO8601 dates problem solved


Purpose

The Challenge: Currently there is no extensible hypertext format for creating, exporting, and sharing project TASKS. Tasks and ToDo items are typically handled by proprietary desktop software clients like mail programs and calendar applications that are not:

  • open to the web development community
  • extensible for future usage scenarios
  • interoperable between applications
  • portable between systems
  • accessible for persons with disabilities


The Vision: To create a fully-functional Task Microformat for 1) open use in home-grown clients, widgets and applications and 2) adopted for integration with existing software applications such as Microsoft Outlook, Mozilla Thunderbird, Mac Mail, and other popular programs.

Participants

Example Tasks

Task Examples are task formats found in the wild that could benefit from semantic mark-up. This is a growing list of examples from all sorts of places including web-based task management widgets as well as full-blown, proprietary desktop applications. These are the examples which will determine the schema for the task microformat.

Known Task Formats

Task Formats will be a running tab of known formats for publishing tasks.

Eventually, I would like to see a chart of how each value from the implicit schema determined by the task-examples is represented in each format, and what formats have additional properties that do not map between them.

Proposed Task Format

A Proposed Task Format will derive from existing formats, incorporating useful patterns while maintaining semantic, extensible markup.
