Abstract
This document describes a Uniform Resource Name (URN) namespace that
is engineered by a consortium (general contractor, Olimps LTD, and
subcontractors, ABC software LTD, Microsoft Latvia LTD, Riga Internet
eXchange (RIX) Technologies LTD, and Microlink LTD) for naming
information resources published and produced by the Latvian National
Government Integration Project (Latvian abbreviation IVIS).

RFC 4617 IVIS URN Definition August 2006
1. Introduction
The IVIS uses and produces many kinds of information resources such
as E-services, E-service instances, specifications, standards,
working documents, and XML schemas. An ID in IVIS has to be unique
for global use every time.
2. Specification Template
Namespace ID:
"IVIS" requested according to [RFC3406].
Registration information:
Registration Version Number: 1
Registration Date: 2006-MM-DD
Declared registrant of the namespace:
Organization: ABC software LTD on behalf of The Secretariat of the
Special Assignments Minister for Electronic Government Affairs
Name: Jurijs Kornijenko
Title: Software Architect
Address: Tallinas - 51, Riga, LV-1012
Phone: +371 7082635
Email: j.kornienko@abcsoftware.lv
Declaration of structure:
The Namespace Specific String (NSS) of all URNs assigned by the
IVIS will have the following hierarchical structure (ABNF,
according to [RFC4234]):
<NID> ::= "IVIS"
<NSS> ::= <IVIS Org ID>:<ResID - suffix>
<IVIS Org ID> ::= 1*<number> { subsystem ID from IVIS database}
<ResID - suffix> ::= 1*(<upper> | <lower> | <number> | <other>)
{an ID generated by IVIS subsystem that is unique within
this subsystem}
Kornijenko Informational [Page 2]
^L
RFC 4617 IVIS URN Definition August 2006
<other> ::= "(" | ")" | "+" | "," | "-" | "." |
"=" | "@" | ";" | "$" |
"_" | "!" | "*"
<upper> ::= "A" | "B" | "C" | "D" | "E" | "F" | "G" | "H" |
"I" | "J" | "K" | "L" | "M" | "N" | "O" | "P" |
"Q" | "R" | "S" | "T" | "U" | "V" | "W" | "X" |
"Y" | "Z"
<lower> ::= "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" |
"i" | "j" | "k" | "l" | "m" | "n" | "o" | "p" |
"q" | "r" | "s" | "t" | "u" | "v" | "w" | "x" |
"y" | "z"
<number> ::= "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" |
"8" | "9"
Relevant ancillary documentation:
IVIS ancillary documentation is under development.
Identifier uniqueness considerations:
Uniqueness is guaranteed by the IVIS that issues the numbers. The
numbers are not reassigned.
Identifier persistence considerations:
Persistence of identifiers is dependent upon the persistence of
the system name assignment by system name holders.
Process of identifier assignment:
All the assignments of identifiers are fully controlled and
managed by the IVIS and its subsystems.
Process of identifier resolution:
The holders of system names are responsible for operating or
delegating resolution servers for the system in which they have
assigned URNs.
Rules for Lexical Equivalence:
The entire URN is case insensitive.

RFC 4617 IVIS URN Definition August 2006
Conformity with URN syntax:
IVIS schema URN fully conforms to [RFC2141] syntax, except that
symbols "'" and ":" were excluded from <other>.
Validation mechanism:
<IVIS Org ID> could be validated by using a special IVIS database
service. <ResID - suffix> could be validated by an appropriate
subsystem.
Scope:
Global.
3. Example
The following examples are not to be real. They are provided for
pedagogical purposes only.
URN:IVIS:000000:DOC-METADATA
URN:IVIS:000000:NDR1021365
4. Community Considerations
Every Latvian ministry's local authority produces many kinds of
different documents, offers public services. Each of the information
resources is already uniquely identified within an authority-
producer. The IVIS URN namespace helps unify information resource
identifiers by using existent Latvian government authority
identification procedures to produce E-services and different
documents where many parties are involved. Any citizen or
organization with Internet web browser capability will be entitled to
access the namespace and its associated application, registration,
and resolution services. The primary IVIS namespace usage is to
identify information resources, such as XML messages, their schemas,
and other resources, which can be public or have a special
destination, when a few different parties are involved in the
interchange.
5. IANA Considerations
This document includes a RUN Network Identifier (NID) registration
for IVIS for entry in the IANA registry of URN NIDs (see [RFC2434]
for more information).

RFC 4617 IVIS URN Definition August 2006
6. Namespace Considerations
To select necessary identifier schema, we spend a lot time and
decided on URN, because an IVIS URN namespace has to resolve the
following problems:
- Information resource uniqueness
Uniqueness makes it possible to find a necessary resource and call
it anytime. Uniqueness gives stability in message sending and
storing operations.
- Namespace understandability
IVIS URN consists of parts, which can guarantee namespace
legibility.
- Information resource resolution
One of the IVIS namespace parts identifies the place where the
resource can be found (resolved).
Therefore, a new URN assignment is required, and individual URNs
shall be assigned through the process of development of each XML
schema.
7. Security Considerations
There are no additional security considerations besides those
normally associated with the use and resolution of URNs in
general.
8. Acknowledgements
Since the specification described in this document is derived from
[RFC3305], [RFC3616], [RFC3986], [RFC3622], and [RFC3406] the
acknowledgements in those documents still apply. In addition, the
author wishes to acknowledge Leslie Daigle, Ted Hardie, and Dinara
Suleymanova for their suggestions and review.
