1. Introduction
This document describes an IRIS registry schema for Internet domain
registries using an XML Schema [4] derived from and using the IRIS
[5] schema. The query and result types outlined in this document are
based on the functional requirements described in CRISP [17].
The schema given is this document is specified by using the
Extensible Markup Language (XML) 1.0, as described in XML [1]; XML
Schema notation, as described in XML_SD [3] and XML_SS [4]; and XML
Namespaces, as described in XML_NS [2].
Examples of client/server XML exchanges with this registry type are
available in Appendix A.
Newton & Sanz Standards Track [Page 2]
RFC 3982 IRIS-Dreg January 2005
2. Document Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in BCP 14, RFC 2119 [10].
3. Schema Description
IRIS requires the derivation of both query and result elements by a
registry schema. These descriptions follow.
References to XML elements without a namespace qualifier are from the
schema defined in Section 4. References to elements and attributes
with the "iris" XML namespace qualifier are from the schema defined
in IRIS [5].
The descriptions contained within this section refer to XML elements
and attributes and their relation to the exchange of data within the
protocol. These descriptions also contain specifications outside the
scope of the formal XML syntax. This section will use terms defined
by RFC 2119 [10] to describe these. While reading this section,
please reference Section 4 for needed details on the formal XML
syntax.
3.1. Query Derivatives
3.1.1. Query
searches for a registration authority
designated as a registrar for the registry of the server.
If present, the element MUST restrict the results of the
search to registrars capable of registering subdomains in the domain
signified by the content of this element.
The element restricts the scope of the query with its
child elements. The element specifies the beginning of
the registrar's name. The element specifies the end of
the registrar's name. The element specifies equivalence
to the registrar's name.
If the element is not present, the query MUST return all
registrars applicable (i.e., in consideration of ).
This query MUST return a result set of zero or more
elements. See Section 3.2.5.
Newton & Sanz Standards Track [Page 3]
RFC 3982 IRIS-Dreg January 2005
3.1.2. Query
finds domains by searches on fields associated
with a domain's contact. A search constraint of MUST
restrict the results to domains underneath the domain specified by
its content, if it is present.
The allowable search fields are handled with either the
element or one of the elements in the
"contactSearchGroup" (see Section 3.1.7). The
element allows the domains to be selected based on the contact having
the specified contact handle.
The query MAY also be constrained further by using the optional
element. The contents of this element signify the role the
contact has with the domain.
This query also provides optional elements containing
language tags. Clients MAY use these elements to hint about the
natural language(s) of the affected element. Servers MAY use this
information in processing the query, such as in tailoring
normalization routines to aid in more effective searches.
3.1.3. Query
The query finds domains by the name of a domain
as it is known in DNS. The element restricts the scope of
the query with its child elements. The element
specifies the beginning of the domain name. The element
specifies the end of the domain name.
3.1.4. Query
This query differs from the query by allowing the
scope of the query to take internationalized domain names into
consideration. This query will return the union of the desired
domain and any associated variants, therefore differing from a lookup
in the "idn" entity class (Section 3.4) (which only returns the
domain or no results).
The element restricts the scope of the query with its
child element. Its child, the element, is designed to
contain IDNs and not ACE labels, and thus MUST match only against
equivalent IDNs, according to the notion of equivalence defined in
RFC 3490 [14].
This query also provides optional elements containing
language tags. Clients MAY use these elements to hint about the
Newton & Sanz Standards Track [Page 4]
RFC 3982 IRIS-Dreg January 2005
natural language(s) of the affected element. Servers MAY use this
information in processing the query, such as in tailoring
normalization routines to aid in more effective searches.
3.1.5. Query
searches for contacts given search constraints. The
allowable search fields are handled by one of the elements in the
"contactSearchGroup" (see Section 3.1.7).
This query also provides optional elements containing
language tags. Clients MAY use these elements to hint about the
natural language(s) of the affected element. Servers MAY use this
information in processing the query, such as in tailoring
normalization routines to aid in more effective searches.
3.1.6. Query
This query does a simple search for the domains being hosted by a
name server. The search is constrained by using either the host name
[12], host handle, IPv4 address, or IPv6 address of the name server.
3.1.7. Contact Search Group
Some of the queries above have similar query constraints for
searching on contacts. This section describes those common
parameters.
allows the query to be constrained based on the common
name of the contact. The constraint can constrain the query either
by an exact match using the element, or by a subset of
the common name using the and elements.
allows the query to be constrained based on the
organization name of the contact. It has the same semantics as the
element.
constrains the query based on the e-mail address of the
contact. This may be done by an exact e-mail address using the
element or by any e-mail address in a domain using the
element. The element MUST only contain a valid
domain name (i.e., without an '@' symbol), and the matching SHOULD
take place only on the domain given (i.e., no partial matches with
respect to substrings or parent domains). If either the contents of
the element or the domain part of the contents of the
element contain a name with non-ASCII characters, they
MUST be normalized according to the processes of RFC 3491 [15].
Newton & Sanz Standards Track [Page 5]
RFC 3982 IRIS-Dreg January 2005
The , , and elements restrict the scope of
the query based on the city, region, or postal code of the contact,
respectively. Each must only contain an element
containing the exact city, region, or postal code (i.e., no substring
searches).
3.2. Result Derivatives
3.2.1. Privacy Labels
Several of the results in this registry type have values that cannot
be given but must be specified as present or must be flagged so that
clients do not divulge them. In order to achieve this, some of the
results use the following element types:
o "dateTimePrivacyType" -- contains the XML Schema [3] data type
"dateTime". The contents of this element MUST be specified by
using the 'Z' indicator for Coordinated Universal Time (UTC).
o "stringPrivacyType" -- contains the XML Schema [3] data type
"string".
o "normalizedStringPrivacyType" -- contains the XML Schema [3] data
type "normalizedString".
o "tokenPrivacyType" -- contains the XML Schema [3] data type
"token".
o "domainStatusType" -- contains the optional element of
, indicating the date and time when the status was
applied, and the optional element of with the
required attribute 'language', indicating a description of the
status. This element also has the optional attribute 'scope',
indicating the scope or origin of the status value.
o "contactTypeType" -- contains optional child
elements. Each child element requires a 'language'
attribute.
As specified, these elements can have nil values and therefore may be
present with empty content or present with their specified content.
The use of these elements is also optional.
If present without content, each of these element types MUST have one
or more of the following boolean attributes:
o 'private' -- If true, this specifies that the content is absent
because it may never be published.
Newton & Sanz Standards Track [Page 6]
RFC 3982 IRIS-Dreg January 2005
o 'denied' -- If true, this specifies that the content is absent
because policy does not allow it to be given at the current level
of access.
If present with content, each of these element types MAY have one or
more of the following boolean attributes:
o 'doNotRedistribute' -- If true, this specifies that the content is
not to be redistributed.
o 'specialAccess' -- If true, this specifies that the content has
been provided due to special access rights.
These boolean attributes SHOULD be used in accordance with the level
of access granted to the recipient of the data. For example, marking
data as 'private' or 'denied' is to be expected if the user is
anonymous or has some other low level of access that does not warrant
viewing that particular data. Likewise, data marked with
'doNotRedistribute' or 'specialAccess' is to be expected if the user
is authenticated and has a high level of access.
3.2.2. Result
An example of a result:
example.com
tcs-com-1
The result represents an instance of a domain assignment.
The children of the element are as follows:
o -- the full name of the domain as it is in DNS. The
contents of this element MUST be a domain name as specified by RFC
1035 [9].
o -- the name of the domain in nameprep form, if applicable.
See RFC 3491 [15].
o -- a registry unique assigned identifier for a
domain.
o -- MUST contain an entity reference to a referent of
type (Section 3.2.3).
o -- contains an entity reference to the registrant of
this domain. The referent MUST be a result (Section
3.2.4).
o Domain contacts -- the following elements contain an entity
reference with a relationship to the domain. The referent of each
MUST be a (Section 3.2.4).

RFC 3982 IRIS-Dreg January 2005
o -- contains an entity reference, the referent of
which MUST be a (Section 3.2.2).
o -- contains an entity reference, the
referent of which MUST be a (Section 3.2.2). This
element is intended to point to the downstream registration
reference. Therefore, if this is a result given back by a domain
registry, it should point to the domain in the domain registrar or
registrant service.
o -- contains an entity reference specifying the domain
registry operator for this domain, which MUST be a
(Section 3.2.5). This element has an
optional boolean 'hosting' attribute. When the value of this
attribute is positive, it indicates that the registry is
responsible for authoritatively answering DNS queries for this
domain.
o -- contains an entity reference specifying the domain
registrar operator for this domain, which MUST be a
(Section 3.2.5). This element has an
optional boolean 'hosting' attribute. When the value of this
attribute is positive, it indicates that the registrar is
responsible for authoratively answering DNS queries for this
domain.
o -- contains the date and time of the
initial delegation of this domain.
o -- contains the date and time of last
renewal of this domain.
o -- contains the date and time of the
expiration of this domain.
o -- specifies the last time a
contact for the domain was added or removed.
o -- contains an entity reference. The
referent MUST be a (Section 3.2.4) responsible for the
last addition or removal of a contact for this domain.
o -- contains the date and time
of the last time one of the nameservers was added or removed for
the delegation of this domain.
Newton & Sanz Standards Track [Page 9]
RFC 3982 IRIS-Dreg January 2005
o -- contains an entity reference.
The referent MUST be a result (Section 3.2.4) and MUST
be responsible for the last addition or removal of a nameserver
for this domain.
o -- contains the date and time of the
last time the data for this domain was verified by the responsible
registration authority.
o -- contains an entity reference specifying a
referent indirectly associated with this domain.
3.2.3. Result
An example of a result:
nsol184
a.iana-servers.net
192.0.2.43
The element represents an instance of a host registration.
The children of the element are as follows:

IP version 6 host address, as specified by RFC 3513 [7].
o -- contains an entity reference specifying a contact
associated with this host. The referent MUST be
(Section 3.2.4) results.
Newton & Sanz Standards Track [Page 10]

host was last modified.
o -- contains the date and time when this
data for this host was last verified to be correct by the
appropriate registration authority.
o -- contains an entity reference specifying a
referent indirectly associated with this host.

RFC 3982 IRIS-Dreg January 2005
3.2.5.
An example of a result:
Internet Assigned Numbers Authority
The result represents an entity capable of
registering domains.
The child element of
contains an entity reference pointing to the entity "id" in the
entity class "iris". The authority areas found in the referent MUST
be domains for which a given registration authority has control.
The child element contains the name of the
registration authority.
The registration authority type child elements ,
, and determine the role this registration
authority plays in the process of registering domains. This element
is intended to explain the various roles a registration authority may
have in the authority areas pointed to by the
element. A client MAY understand the relationship of a registration
authority with respect to a domain by the placement of the reference
in the domain (e.g., or ).
The child elements each contain one domain name signifying
the domains for which this registration authority may register sub-
domains.
3.3. Generic Code Derivatives
3.3.1.
Servers MAY use the error code when a query must be
narrowed to yield a result set acceptable under the policies of the
server operator.
Newton & Sanz Standards Track [Page 13]
RFC 3982 IRIS-Dreg January 2005
3.3.2.
The queries , , and
support optional language tags that allow a client to
suggest to a server the languages in which to scope the queries. If
a client passes to the server a language that the server does not
support, the server MAY use this error code to indicate that one of
the languages is not supported.
This element contains child elements named .
Each of these child elements specifies a language not supported by
the server. When a server returns this error, it MUST give the
languages from the query which are not supported.
3.4. Support for
The following types of entity classes are recognized by the
query of IRIS for this registry:
o host-name -- The fully qualified domain name of a nameserver. It
yields a (Section 3.2.3) in the response.
o host-handle -- The registry unique identifier given a nameserver.
It yields a (Section 3.2.3) in the response.
o domain-name -- The fully qualified name of a domain. This a
domain name as specified by RFC 1035 [9]. It yields a
(Section 3.2.2) in the response.
o idn -- The fully qualified name of a domain in nameprep form (see
RFC 3491 [15]). It yields a (Section 3.2.2) in the
response.
o domain-handle -- The registry unique identifier given a domain.
It yields a (Section 3.2.2) in the response.
o contact-handle -- The registry unique identifier given a contact.
It yields a (Section 3.2.4) in the response.
o ipv4-address -- The IPv4 address of a nameserver. It yields a
(Section 3.2.3) in the response.
o ipv6-address -- The IPv6 address of a nameserver. It yields a
(Section 3.2.3) in the response.
o registration-authority -- The name of a registration authority.
It yields a (Section 3.2.5) in the
response.
Newton & Sanz Standards Track [Page 14]
RFC 3982 IRIS-Dreg January 2005
All names in these entity classes are case insensitive.
4. Formal XML Syntax
This registry schema is specified in the XML Schema notation. The
formal syntax presented here is a complete schema representation
suitable for automated validation of an XML instance when combined
with the formal schema syntax of IRIS.

RFC 3982 IRIS-Dreg January 2005
Figure 5: dreg.xsd
5. BEEP Transport Compliance
IRIS allows several extensions of the core capabilities. This
section outlines extensions allowable by IRIS-BEEP [6].
5.1. Message Pattern
This registry type uses the default message pattern described in
IRIS-BEEP [6].
5.2. Server Authentication
This registry type only uses the basic TLS server authentication
method, as described in IRIS-BEEP [6].
6. URI Resolution
6.1. Application Service Label
The application service label associated with this registry type MUST
be "DREG1". This is the abbreviated form of the URN for this
registry type: urn:ietf:params:xml:ns:dreg1.
Newton & Sanz Standards Track [Page 36]
RFC 3982 IRIS-Dreg January 2005
6.2. Bottom-Up Resolution
The bottom-up alternative resolution method MUST be identified as
'bottom' in IRIS URI's.
The process for this resolution method differs from the direct-
resolution method if the authority is only a domain name (i.e.,
without the port number). The process for this condition is as
follows:
1. The IRIS [5] direct-resolution process is tried on the domain name
(e.g., "example.com").
2. If the direct-resolution process yields no server for which a
connection can be made, then the leftmost label of the domain name
is removed, and the first step is repeated again (e.g., "com").
3. If all the labels of the domain name are removed and no server
connections have been made, then the DNS is queried for the
address records corresponding to the original domain name, and the
port used is the well-known port for the default protocol of IRIS.
6.3. Top-Down Resolution
The top-down alternative resolution method MUST be identified as
'top' in IRIS URIs.
The process for this resolution method differs from the direct-
resolution method if the authority is only a domain name (i.e.,
without the port number). The process for this condition is as
follows:
1. The domain name is reduced to its rightmost label. This is always
'.'.
2. The IRIS [5] direct-resolution process is tried on the domain
name.
3. If the direct-resolution process yields no server for which a
connection can be made, then the original label to the left of the
rightmost label of the domain name is prepended, and the second
step is repeated again (e.g., if ".", then "com"; if "com", then
"example.com").
4. If all the labels of the original domain are present and no server
connections have been made, then the DNS is queried for the
address records corresponding to the original domain name, and the
port used is the well-known port for the default protocol of IRIS.

RFC 3982 IRIS-Dreg January 2005
7. Internationalization Considerations
Implementers should be aware of considerations for
internationalization in IRIS [5].
This document specifies the lookup of domain names, both the
traditional ASCII form and the IDN form. In addition, the social
data associated with contacts may also be non-ASCII and could contain
virtually any Unicode character. The element is provided
in queries that have the potential to traverse such data. Clients
should use this element to indicate the desired target languages to
the server, and servers should use this element to better enable
normalization and search processes (see [18]).
For clients needing to localize the data tags in this protocol, note
that localization is only needed on the names of XML elements and
attributes with the exception of elements containing date and time
information. The schema for this registry has been designed so that
clients need not interpret the content of elements or attributes for
localization, other than that of elements containing date and time
information.
Clients should also make use of the elements provided in
many of the results. Results containing data that may be in Unicode
are accompanied by these elements in order to aid better presentation
of the data to the user.
The "dateTimePrivacyType" element type contains the XML Schema [3]
data type "dateTime". The contents of this element MUST be specified
by using the 'Z' indicator for Coordinated Universal Time (UTC).
8. IANA Considerations
8.1. XML Namespace URN Registration
This document makes use of a proposed XML namespace and schema
registry specified in XML_URN [16]. Accordingly, the following
registration information is provided for the IANA:
o URN/URI:
* urn:ietf:params:xml:ns:dreg1
o Contact:
* Andrew Newton
* Marcos Sanz
o XML:
* The XML Schema specified in Section 4

8.2. S-NAPTR Registration
The following S-NAPTR application service label has been registered
with IANA according to the IANA considerations defined in IRIS [5]:

Appendix C. Acknowledgements
Many of the concepts concerning the use of SRV records for step-wise
refinement toward finding authoritative servers and many of the
details of result objects in this document were originally created by
Eric A. Hall in his memos regarding the use of LDAP to satisfy the
CRISP requirements. These concepts have contributed significantly to
the development of this protocol.
David Blacka made many technical contributions based on his work on
IRIS implementation and his experienced judgment. He also
contributed many editorial clarifications.
