Proposal to Form the OASIS XRI Data Interchange (XDI) Technical Committee

Charter

The following comprises the TC Charter:

Name of the TC

OASIS XRI Data Interchange (XDI) Technical Committee

Statement of Purpose

As the Internet increasingly becomes the common data interchange platform for all devices, domains, and networks, there is a growing need for a simple, standard way to share data that is common to multiple applications, directories, databases, Web services, and XML schemas while at the same time permitting the authorities for this data to secure, protect, and control its use.

The purpose of the OASIS XDI TC is to define a generalized, extensible, location-, application-, and transport-independent service for sharing, linking, and synchronizing data over the Internet and other data networks using XML documents and XRIs (Extensible Resource Identifiers), a URI-compatible abstract identifier scheme defined by the OASIS XRI Technical Committee. With XDI, data from any data source can be identified, described, linked, and synchronized into an active, machine-readable "dataweb" just as content from any content source can be identified and linked into the human-readable Web today.

A particular purpose of XDI is to allow the controls needed to mediate access and usage of shared data to be expressed as XDI links. These data sharing controls can govern authority, authentication, authorization, access control, usage control, transmission, synchronization, and rights management. The integration of such controls into a common, generalized data-oriented service can provide a new platform for trusted data sharing networks and applications.

In no event shall this Technical Committee finalize or approve any technical specification if it believes that the use, distribution, or implementation of such specification would necessarily require the unauthorized infringement of any third party rights known to the Technical Committee, and such third party has not agreed to provide necessary license rights on perpetual, royalty-free, non-discriminatory terms.

Scope of Work

As a data sharing service, XDI is intended to be very simple and generalized, much like HTTP or SMTP. Similarly, the XDI meta-schema is intended to be a very simple and generalized XML schema that can be used either to carry or to describe data encoded in other XML schema languages or referenced externally (much as HTML can either carry content or reference it externally). Such a "lingua franca" for XML data interchange can be used to solve many problems related to mapping and sharing of data and metadata across domains, directories, schemas, ontologies, applications, and languages (both human and machine).

Therefore, although the potential uses of XDI are very broad, the scope of work of the OASIS XDI TC is relatively narrow. Specifically, it is limited to:

Defining the XDI meta-schema for describing and linking XRI-identified resources.
Defining XRI resolution rules within XDI documents.
Defining the WSDL for XDI service and bindings to common transport protocols such as HTTP, SOAP, and SMTP/MIME.
Defining the XDI service dictionary -- the set of globally-shared XDI resources that can be used to define, control, secure, and protect data sharing relationships using XDI.
Maintaining additional versions of these specifications as they evolve over time.

The OASIS XDI TC may also publish white papers, example usage scenarios, and other documentation to support XDI implementation and adoption.

List of Deliverables

The initial deliverables of the OASIS XDI TC and their completion dates are:

XDI Use Cases and Requirements 1.0 -- 15 May 2004
XDI Service Specification 1.0 (includes XDI Meta-Schema Definition, XDI Addressing Specification, and XDI WSDL Definition and Bindings) -- 15 September 2004
XDI Service Dictionary 1.0 -- 15 Nov 2004

Anticipated Audience or Users of the Work

The work of the OASIS XDI TC will be used by developers and implementers of Web, Web services, and Semantic Web technologies. It will be particularly relevant to architects of trusted computing infrastructure, distributed directory and PKI systems, enterprise application integration (EAI) systems, shared ontologies, and other cross-domain data sharing systems and services.

Language

All meetings (both face-to-face and phone meetings) as well as official correspondences amongst OASIS XDI TC participants will be conducted in English.

Additional Information

The following is additional non-normative information related to starting the TC.

Similar Work Done in Other OASIS TCs and Related Standards Bodies

The work done in the OASIS XDI TC is related to the following work done in other OASIS TCs:

XRIs and the OASIS Extensible Resource Identifier TC. The OASIS XDI TC's work is based directly on the specifications for abstract, persistent, location-independent identifiers published by the OASIS XRI TC.
SAML (OASIS Security Services TC), WS-Security (OASIS Web Services Security TC), and the OASIS Public Key Infrastructure TC. The OASIS XDI TC intends to leverage this work by using SAML assertions and WS-Security specifications in the XDI/SOAP binding, and to explore the use of XDI for distributed PKI systems.
XACML (OASIS eXtensible Access Control Markup Language TC) and the OASIS Rights Language TC. XDI can encapsulate existing or emerging access control and rights expression languages directly into its data sharing controls.
DSML and the OASIS Directory Services Markup Language TC. XDI can provide a high-level directory abstraction interface that can interoperate with DSML and LDAP, and XDI can add data sharing controls not currently specified by DSML or LDAP.
SPML and the OASIS Provisioning Services TC. XDI can provide a common format for interchange of SPML attributes, and XDI forms can trigger SPML provisioning requests.
Topic Maps and the OASIS Topic Maps Published Subjects TC. XRIs, XDI documents, and the XDI protocol can provide a robust mechanism for implementing topic maps, and in particular fulfill the OASIS Topic Maps Published Subjects TC's recommendations for Published Subject Indicators (PSIs) and Publish Subject Identifiers (PSIDs).

In addition, the OASIS XDI TC anticipates building on work done at the W3C, including the entire family of Web services standards (XML, XML Schemas, SOAP, WSDL). The XDI TC will also closely examine the use of RDF for data description and OWL for ontology description.

Liaisons

The proposers of the OASIS XDI TC anticipate that the TC will form liaisons with:

The Trusted Computing Group (TCG) Infrastructure Working Group for establishing common use cases and ensuring interoperability of TCG and XDI specifications in trusted computing infrastructure.
The Telemanagement Forum (TMF) for establishing common use cases and requirements for using XDI as a mechanism for implementing the TMF SID (Shared Information/Data Model) component of the TMF NGOSS (New Generation Operations System and Software) program.
The International Security, Trust, and Privacy Alliance (ISTPA) to adapt the ISTPA Privacy Framework as a reference model for XDI privacy architecture and development of usage control vocabulary in the XDI Service Dictionary.

List of Contributions of Existing Technical Work

The proposers of the OASIS XDI TC expect the following work will be contributed to the TC at its first meeting:

The XNS 1.0 and 1.1 Technical Specifications will be contributed by the XNS Public Trust Organization (XNSORG).
An initial XDI meta-schema definition and supporting documentation will also be contributed by XNSORG.

First TC Meeting

The first OASIS XDI TC meeting will be held on the 20th of February 2004, via telecon, at 2pm PT (GMT-8:00).

Meeting Schedule

1. Face-to-Face Meetings: April 29-30, 2004 (tentative)
