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 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.

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 RFC2119 [10].

Internet-Draft iris-dreg April 2004
3. Schema Description
IRIS requires the derivation of both query and result elements by a
registry schemas. These descriptions follow.
References to XML elements with no 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. Therefore, this section will use
terms defined by RFC 2119 [10] to describe the specification outside
the scope of the formal XML syntax. While reading this section,
please reference Section 4 for needed details on the formal XML
syntax.
3.1 Query Derivatives
3.1.1 <findRegistrarsByName> Query
<findRegistrarsByName> searches for a registration authority
designated as a registrar for the registry of the server.
If present, the <baseDomain> element MUST restrict the results of the
search to only registrars capable of registering subdomains in the
domain signified by the content of this element.
The <namePart> element restricts the scope of the query with its
child elements. The <beginsWith> element specifies the beginning of
the registrar's name. The <endsWith> element specifies the end of the
registrar's name. The <exactMatch> element specifies an equivalence
to the registrar's name.
If the <namePart> element is not present, the query MUST return all
registrars applicable (i.e. in consideration of <baseDomain>).
This query MUST return a result set of zero or more
<registrationAuthority> elements. See Section 3.2.5.
3.1.2 <findDomainsByContact> Query
<findDomainsByContact> finds domains by searches on fields associated
with a domain's contact. A search constraint of <baseDomain> MUST
restrict the results to domains only underneath the domain specified
by its content if it is present.
Newton & Sanz Expires October 14, 2004 [Page 5]
Internet-Draft iris-dreg April 2004
The allowable search fields are handled with either the
<contactHandle> element or one of the elements in the
"contactSearchGroup" (see Section 3.1.7). The <contactHandle> element
allows for the domains to be selected based on the contact having the
specified contact handle.
The query MAY also be constrained further using the optional <role>
element. The contents of this element signify the role the contact
has with the domain.
This query also provides optional <language> elements containing
language tags. Clients MAY use these elements to give a hint about
the natural language(s) of the affected element. Servers MAY use this
information in processing the query, such as tailoring normalization
routines to aid in more effective searches.
3.1.3 <findDomainsByName> Query
The <findDomainsByName> query finds domains by the name of a domain
as it is known in DNS. The <namePart> element restricts the scope of
the query with its child elements. The <beginsWith> element specifies
the beginning of the domain name. The <endsWith> element specifies
the end of the domain name.
3.1.4 <findDomainsByIDN> Query
This query differs from the <findDomainsByName> query by allowing the
scope of the query to take into consideration internationalized
domain names. 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 is to only return the domain
or no results).
The <namePart> element restricts the scope of the query with its
child element. Its child, the <exactMatch> 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 <language> elements containing
language tags. Clients MAY use these elements to give a hint about
the natural language(s) of the affected element. Servers MAY use this
information in processing the query, such as tailoring normalization
routines to aid in more effective searches.
3.1.5 <findContacts> Query
<findContacts> searches for contacts given search constraints.
Newton & Sanz Expires October 14, 2004 [Page 6]
Internet-Draft iris-dreg April 2004
The allowable search fields are handled by one of the elements in the
"contactSearchGroup" (see Section 3.1.7).
This query also provides optional <language> elements containing
language tags. Clients MAY use these elements to give a hint about
the natural language(s) of the affected element. Servers MAY use this
information in processing the query, such as tailoring normalization
routines to aid in more effective searches.
3.1.6 <findDomainsByHost> Query
This query does a simple search for the domains being hosted by a
name server. The search is constrained 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.
<commonName> allows the query to be constrained based on the common
name of the contact. The constraint can either constrain the query by
an exact match using the <exactMatch> element, or it may constrain
the query by a subset of the common name using the <beginsWith> and
<endsWith> elements.
<organization> allows the query to be constrained based on the
organization name of the contact. It has the same semantics as the
<commonName> element.
<eMail> constrains the query based on the e-mail address of the
contact. This may be done by an exact e-mail address using the
<exactMatch> element or by any e-mail address in a domain using the
<inDomain> element. The <inDomain> MUST only contain a valid domain
name (i.e. no '@' 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 <inDomain> element
or domain part of the contents of the <exactMatch> element contain a
name with non-ASCII characters, they MUST be normalized according to
the processes of RFC 3491 [15].
The <city>, <region>, and <postalCode> elements restrict the scope of
the query based on the city, region, or postal code of the contact,
respectively. Each one must only contain an <exactMatch> 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 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 an optional element of <appliedDate>
indicating the date and time the status was applied and an
optional element of <description> with required attribute
'language' indicating a description of the status. This element
also has an optional attribute of 'scope' to indicate the scope or
origin of the status value.
o "contactTypeType" - contains an optional <description> child
elements. Each <description> child element requires a 'language'
attribute.
As specified, they are nillable and therefore may be present with
empty content or present with their specified content. And their
specified cardinality allows their absence.
Each of these element types MUST have one or more of the following
boolean attributes if they are present without content:
o 'private' - if true, this specifies that the content is absent
because it may never be published.
o 'denied' - if true, this specifies that the content is absent
because policy does not allow it to be given under the current
level of access.
Each of these element types MAY have one or more of the following
boolean attributes if they are present with content:
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.

contents of this element MUST be a domain name as specified by RFC
1035 [9].
o <idn> - the name of the domain in nameprep form if applicable. See
RFC 3491 [15].
o <domainHandle> - a registry unique assigned identifier to a
domain.

type <host> (Section 3.2.3).
o <registrant> - an element containing an entity reference to the
registrant of this domain. The referent MUST be a <contact>
(Section 3.2.4) result.
o Domain contacts - the following elements contain an entity
reference with a relationship to the domain. The referent of each
MUST be a <contact> (Section 3.2.4).

and be responsible for the last addition or removal of a
nameserver for this domain.
o <lastVerificationDateTime> - an element containing the date and
time of the last time the data for this domain was verified by the
responsible registration authority.
o <iris:seeAlso> - an element containing an entity reference
specifying a referent that is indirectly associated with this

3.2.5 <registrationAuthority>
An example of a <registrationAuthority> result:
Newton & Sanz Expires October 14, 2004 [Page 13]
Internet-Draft iris-dreg April 2004
<registrationAuthority
authority="iana.org" registryType="dreg1"
entityClass="registration-authority" entityName="iana" >
<serviceInstance
iris:referentType="iris:serviceIdentification"
authority="iana.org" registryType="dreg1"
entityClass="iris" entityName="id" />
<organizationName>
Internet Assigned Numbers Authority
</organizationName>
<registrar />
</registrationAuthority>
The <registrationAuthority> result represents an entity capable of
registering domains.
The <serviceInstance> child element of <registrationAuthority>
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 <organizationName> child element contains the name of the
registration authority.
The registration authority type child elements, <registry>,
<registrar>, and <other>, determine the role in which this
registration authority plays in the process of registering domains.
The intent of this element is to explain the various roles a
registration authority may have with regards to the authority areas
pointed to by the <serviceInstance> 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. <registry> or
<registrar>).
The <domain> 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 <searchTooWide>
Servers MAY use the <searchTooWide> error code when a query must be
narrowed to yield a result set acceptable to the policies of the
server operator.
Newton & Sanz Expires October 14, 2004 [Page 14]
Internet-Draft iris-dreg April 2004
3.3.2 <languageNotSupported>
The queries <findDomainsByRegistrant>, <findDomainsByIDNName>, and
<findContacts> 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 which 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 <unsupportedLanguage>.
Each of these child elements specify 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 <iris:lookupEntity>
The following types of entity classes are recognized by the
<lookupEntity> query of IRIS for this registry:
o host-name - the fully qualified domain name of a nameserver.
Yields a <host> (Section 3.2.3) in the response.
o host-handle - the registry unique identifier given a nameserver.
Yields a <host> (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]. Yields a <domain> (Section

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.

5. BEEP Transport Compliance
IRIS allows several extensions of the core capabilities. This section
outlines those extensions allowable by IRIS-BEEP [6].
5.1 Message Pattern
This registry type uses the default message pattern as described in
IRIS-BEEP [6].
5.2 Server Authentication
This registry type uses the default server authentication method as
described in IRIS-BEEP [6].
Newton & Sanz Expires October 14, 2004 [Page 38]
Internet-Draft iris-dreg April 2004
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.
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 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 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").

Internet-Draft iris-dreg April 2004
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

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 <language> element is provided
in queries that have potential to traverse such data. Clients should
use these elements to indicate to the server of the target languages
desired, and servers should use these elements to better enable
normalization and search processes (see [18]).
Clients needing to localize the data tags in this protocol should
take 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 those elements containing
date and time information.
Clients should also make use of the <language> 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
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 <andy@hxr.us>
* Marcos Sanz <sanz@denic.de>
o XML:
* The XML Schema specified in Section 4
8.2 S-NAPTR Registration
The following S-NAPTR application service label will need to be
registered with IANA according to the IANA considerations defined in
IRIS [5]:
DREG1
8.3 BEEP Registration
The following BEEP Profile URI is to be registeried with IANA, in
addition to the registration provided in IRIS-BEEP [6].

Appendix C. Acknowledgements
Many of the concepts concerning the use of SRV records for step-wise
refinement towards finding authoritative servers and many of the
details of result objects in this draft 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 gave many technical contributions due to work on his
IRIS implementation and experienced judgement. He also contributed
many editorial clarifications.
