Fwd: WG Review: JSON data formats for vCard and iCalendar (jcardcal)

Thomas Roessler
FYI.  This work sounds like it might overlap with some of the work in the W3C systems API and device API Working Groups.  Probably worth discussing in some detail on the next liaison call.

> Problem Statement:
>
> The standard iCalendar [RFC5545] and vCard [RFC6350] data formats are in
> widespread use for calendaring and contacts data exchange. In addition
> to the text formats described in the base specifications, alternative
> XML formats have been defined ([RFC6321] and [RFC6351] respectively).
> Interest has been expressed in also having JSON [RFC4627] formats for
> both iCalendar and vCard to allow easier integration of such data with
> web or other Javascript based applications, and other JSON-based
> protocols being developed by IETF working groups such as jose, scim, and
> weirds.

> Because iCalendar and vCard formats have a similar schema (a
> component/property/parameter/value model) it is often the case that
> iCalendar and vCard data handling is carried out by libraries with a
> high degree of code re-use for each format. It is thus highly desirable
> that the JSON formats for iCalendar and vCard are aligned in terms of
> their JSON structures so that the policy of code re-use for
> iCalendar/vCard parsing/generation can continue.

> Objectives:
>
> The jcardcal working group is chartered to develop JSON-based data
> formats that are accurate, straightforward representations of iCalendar
> and vCard data, allowing for conversion between any of the various
> equivalent data formats without any loss of semantic meaning, and
> maximal interoperability.
>
> Consideration will be given to compactness and readability of the JSON
> data formats, whilst at the same time maintaining the underlying data
> models of the respective original formats. The JSON formats will re-use
> the extensibility model of the base formats. The JSON formats will use
> similar data models in JSON to allow for optimal code re-use when
> parsing/generating jCard and jCal.

> Syntactic requirements from other working groups looking to adopt
> the jCard or jCal data formats will be considered. However, changes
> to the semantics of vCard and iCalendar are out of scope.
> Requirements that are not explicitly mentioned in this charter will
> be considered so long as they do not conflict with the other stated
> objectives. Specific requirements for consideration are:

> Milestones:
>
>  Mar 2013 - Determine initial requirements of other Working Groups.
>  Mar 2013 - Accept jCard and jCal documents as Working Group items.
>  May 2013 - Request publication of jCard document.
>  Jun 2013 - Request publication of jCal document.
