XML Encryption Charter [ascii] XML Encryption Charter [ascii]XML Encryption is a method whereby XML content can be transformed such that it is discernable only to the intended recipients, and opaque to all others. There are many applications for such a specification given the increasing importance of XML on the Internet and Web including the protection of payment and transaction information. The proposed work will obviously address how to encrypt an XML documents including elements.
The mission of this working group is to develop a process for encrypting/decyrpting digital content (including XML documents and portions thereof) and an XML syntax used to represent the (1) encrypted content and (2) information that enables an intendent recipient to decrypt it.
The core scope of this activity will be in specifying the necessary data model, syntax, and processing to encrypt XML content.
The Working Group (WG) will:
The requirement document must specify and describe the WG's choice with respect to the granularity of encryption, the data model and representation resulting from that choice, and the necessity and choice of canonicalization algorithms. The WG must rely upon existing W3C specifications as building blocks to its own design, unless the WG can demonstrate these specifications fail to meet the requirements of XML Encryption applications. In which case the WG must give a strong rationale and obtain Director approval.
The following additional requirements must be met by the WG; these requirements must be augmented and extended by the Requirements Document deliverable:
The working group will not address the following issues:
It is hoped that the following applications being developed by members of the WG will provide a useful test of the completeness:
This working group will deliver the following:
This Working Group is scheduled for ten months. Currently, its expected lifetime is from January 2001 through October 2001. Last Call candidates should be available by June 2001.
Once established, the Working Group can decide to parallelize tasks by forming subgroups. These dates are subject to revision due to editorial needs and external scheduling issues; updates will be negotiated with the affected working groups and participants and recorded on the XML Encryption WG home page. Any change in a deliverable date must be brought to the attention of the W3C Domain leader and Director.
This charter, the WG web page, and the mailing list and archives will be publicly accessible.
During W3C Last Call, the Chair will procure reviews from the following W3C WGs before the specification will be advanced further:
Since this Working Group will be public, its coordination with other W3C WGs must take this into account.
Working group members are expected to participate in an electronic mailing list, periodic teleconferences and face-to-face meetings. The WG consensus venue is the mailing list. Note, straw polls and assessments of consensus may be taken on teleconferences and face-to-face meetings which will then be sent to the list via minutes. If those decision are not opposed or questioned on the list, they naturally stand as the WG's consensus.
(See Participants for information on the roles and commitments of working group members.)
NOTE: The proceedings of this Working Group are public.
In order to maintain shared context of the group and to provide access to the proceedings of the group, the Chair maintains a web page at http://www.w3.org/Encryption/2001/ .
Active participants are expected to have ready access to this page and be familiar with its contents.
Participants must subscribe to and participate in the public mailing list: <xml-encryption@w3.org>.
As necessary, the Chair may convene teleconferences periodically for the purpose of quickly addressing and resolving open issues and tracking action items and deliverables.
The Chair is responsible for producing an agenda at least 24 hours in advance of each call, posting it along with the call details to the mailing list, and causing minutes of the call to be posted promptly after the call.
A public IRC channel should be available to complement/coordinate teleconference discussion. However, the IRC conversation is not necessarily part of the record: it must be stated on the teleconference as an IRC message is not necessarily a sufficient communication to the others on the teleconference.
The working group will have a day face to face meeting in February 2001. Meeting notice, advance agenda, and posting of minutes shall follow W3C timing rules.
This working group is public.
W3C promotes an open working environment. Whenever possible, technical decisions should be made unencumbered by intellectual property right (IPR) claims. W3C's policy for intellectual property is set out in section 1.5 of the W3C Process document.
Members of the XML Encryption Working Group and any other Working Group constituted within the XML Encryption Activity are expected to disclose any intellectual property they have in this area. Any intellectual property essential to implement specifications produced by this Activity must be at least available for licensing on a royalty-free basis. At the suggestion of the Working Group, and at the discretion of the Director of W3C, technologies may be accepted if they are licensed on reasonable, non-discriminatory terms.
Members disclose patent and other IPR claims by sending email to the publicly archived WG list and the archived patent issues list (that is readable by W3C Members and the W3C team): patent-issues@w3.org. Members must disclose all IPR claims to this mailing list but they may also copy other recipients.
This section describes the expectations and requirements of Staff, Member, and Public commitment necessary for this Working Group to be started -- and eventually succeed. The actual roles (chair, author, editor, contributor, implementor) and definitions are be defined by W3C Process and derivation of the XML Signature Working Group Contributor Policies.
Contributors to this working group are expected to commit to 15% (6 hours a week). Commitments for Author and Editor positions are 25% and 35% respectively -- with occasional crunch periods of %50.
The working group has a W3C staff contact (who might also serve as (co)chair and requirements editor). It is expected the staff contact commitment (including requirements management and participation in any WGs that must be coordinated with) will take 30% of staff time. Chairing takes an additional 40%.
This is a public working group and anyone may contribute to the Working Group. However, at the outset of the Activity, the interested W3C member organizations are expected to identify one or more individual contributors to the Working Group and the level of contribution at which they are willing to participate.
Public contributors are welcome to commit to the completion of any action item or to the fulfillment of the roles described in the Contributor Policies. Note, materials sent to the public list are part of the W3C site and subject to W3C policies and licenses. The W3C holds the copyright of all Working Group deliverables (e.g., specifications).
