Abstract This document describes a URN namespace that is owned by the Author and used for documents and XML fragments generated by the author for public use. 1. Introduction This document describes the namespace and registration template for the 'microsoft-com' URN namespace ID. The author produces various documents, applications and XML fragments that require persistent identifiers by which those items can be identified in document management systems and XML applications. Mealling Expires April 1, 2003 [Page 1] Internet-Draft The 'microsoft-com' URN Namespace October 2002 This namespace specification is for a formal namespace. 2. Specification Template Namespace ID: "microsoft-com" requested. Registration Information: Registration Version Number: 1 Registration Date: 2002-09-30 Declared registrant of the namespace: Michael Mealling 950 Herrington Drive, Suite C-190 Lawrenceville, BA 30044 Declaration of structure: The structure of the NSS is a flat space of alphanumeric characters which have no knowable structure outside of the context of author's resolution service. Future changes to the assignement methods may allow others to assign sub-spaces of the flat namesapce but again, this knowledge is only valid internally and should never be inferred or relied upon externally. Relevant ancillary documentation: None Identifier uniqueness considerations: Mealling Expires April 1, 2003 [Page 2] Internet-Draft The 'microsoft-com' URN Namespace October 2002 Identifiers are assigned by the author via a proprietary registration system in a way that guarantees uniqueness. At this time the algorithm is to iterate from the last assigned number by some positive integer. In the future this algorithm may change to incorporate a full range of alphanumeric elements. In either case, the system will compare the newly created identifier with all of the previous ones to ensure that it has not already been assigned. Identifier persistence considerations: The assignment process guarantees that names are not reassigned and that the binding between the name and the resource is permanent, regardless of any document name changes, corporate restructuring, death or dissoluion. Process of identifier assignment: Names are granted via the author via proprietary registration procedures. Process of identifier resolution: Resolution is provided via URN resolvers run by the author. Rules for Lexical Equivalence: The entire URN is case-insensitive. Conformance with URN Syntax: There are no additional characters reserved. Validation mechanism: None additional to resolution specified Mealling Expires April 1, 2003 [Page 3] Internet-Draft The 'microsoft-com' URN Namespace October 2002 Scope: Global 3. Examples The following examples are not guaranteed to be real. They are listed for pedagogical reasons only. URN:microsoft-com:bs4321234 URN:microsoft-com:324kj5hkj45 URN:microsoft-com:mm2136 4. Security Considerations Since the URNs in this namespace are opaque there are no additional security considerations other than those normally associated with the use and resolution of URNs in general.
