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 [11].
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 [13].

Internet-Draft iris-dreg June 2003
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 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 [13] 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 <listRegistrars> Query
This query MUST return a result set of zero or more
<registrationAuthority> elements. See Section 3.2.6.
3.1.2 <findDomainsByRegistrant> Query
<findDomainsByRegistrant> finds domains by searches on fields
associated with a domain's registrant. A search constraint of
<baseDomain> MUST restrict the results to domains only underneath the
domain specified by its content if it is present.
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 registrant having
the specified contact handle.
This query also provides optional <language> elements containing
language tags. Clients may use these elements to inform the server
of a desired search algorithm that may benefit from the determination
of the desired languages. Servers MAY use this information in
processing the query, such as input to normalization routines to aid
in more effective searches.
3.1.3 <findDomainsByName> Query
The <findDomainsByName> query finds domains by the name of a domain
Newton Expires December 29, 2003 [Page 5]
Internet-Draft iris-dreg June 2003
as it is known in DNS. A search constraint of <baseDomain> MUST
restrict the results to domains only underneath the domain specified
by its content if it is present. The content of this element MUST be
a valid domain name according to RFC 1035 [12]. 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. The contents
of <beginsWith> and <endsWith> elements MUST be ASCII.
3.1.4 <findDomainsByI18NName> Query
The <findDomainsByI18NName> query finds a domains by the name of the
domain as it is known in DNS. It differs from the <findDomainsByName>
query by allowing the scope of the query to take into consideration
internationalized domain names.
A search constraint of <baseDomain> MUST restrict the results to
domains only underneath the domain specified by its content if it is
present. The content of this element MUST be a valid domain name
according to RFC 1035 [12]. 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.
This query also provides optional <language> elements containing
language tags. Clients may use these elements to inform the server
of a desired search algorithm that may benefit from the determination
of the desired languages. Servers MAY use this information in
processing the query, such as input to normalization routines to aid
in more effective searches.
3.1.5 <findContacts> Query
<findContacts> 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 <language> elements containing
language tags. Clients may use these elements to inform the server
of a desired search algorithm that may benefit from the determination
of the desired languages. Servers MAY use this information in
processing the query, such as input to 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
Newton Expires December 29, 2003 [Page 6]
Internet-Draft iris-dreg June 2003
name server. The search is constrained using either the host name,
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 <startsWith> 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
according to RFC 1035 [12] (i.e. no '@' symbol).
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 Omission Types
Several of the results in this registry type have values that cannot
be given but must be specified as present. In order to achieve this,
some of the results use the following element types:
o "dateTimeOmissionType" - contains the XML Schema [3] data type
"dateTime".
o "stringOmissionType" - contains the XML Schema [3] data type
"string".
o "normalizedStringOmissionType" - contains the XML Schema [3] data
type "normalizedString".
Newton Expires December 29, 2003 [Page 7]
Internet-Draft iris-dreg June 2003
o "tokenOmissionType" - contains the XML Schema [3] data type
"token".
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.
o 'unspecified' - if true, this specifies that the content is absent
for an unspecified reason.
3.2.2 <domain> Result
The <domain> result represents an instance of a domain assignment.
The children of the <domain> element are as follows:
o <domainName> - 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 [12].
o <domainHandle> - a registry unique assigned identifier to a
domain.
o <nameServers> - an element containing multiple children. Each
child is an <iris:entity> element as described by IRIS [5]. The
referent of each <iris:entity> element MUST be a <host> (Section
3.2.4) result.
o <registrant> - an element containing a <iris:entity> reference to
the registrant of this domain. The referent MUST be a <contact>
(Section 3.2.5) result.
o Domain contacts - the following elements contain contacts with a
relationship to the domain. The children of these elements are
<iris:entity> elements as described by IRIS [5]. The referent of
each <iris:entity> element MUST be a <contact> (Section 3.2.5)
result.

The <domainVariant> result represents an instance of a
internationalized domain name variant. The children of the
<domainVariant> element are as follows:
o <domainName> - 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 [12].
o <domainVariantHandle> - a registry unique assigned identifier to a
domain variant..
o <variantOf> - an element with a child of <iris:entity>. The
referent MUST be a <domain> (Section 3.2.2) result and be the
internationalized domain name for which this is a variant.

Internet-Draft iris-dreg June 2003
o <blockedStatus> - an element indicating that this variant is
blocked from registration.
o <unblockedStatus> - an element indicating that this variant is not
blocked from registration.
o <registeredDomain> - an element with a child of <iris:entity>. The
referent MUST be a <domain> (Section 3.2.2) result and be the

The <host> element represents an instance of a host registration. The
children of the <host> element are as follows:
o <hostHandle> - a registry unique assigned identifier for the host.
o <hostName> - the fully qualified domain name of the host. The
contents of this element are a domain name and MUST conform to RFC
1035 [12].

content of which MUST conform to the a valid IP version 6 host
address as specified by RFC 2373 [7].
o <hostContact> - a list of <iris:entity> elements specifying
contacts associated with this host. The referents MUST be
<contact> (Section 3.2.5) results.
o <createdDateTime> - an element containing the date and time this
host was created.
o <lastModificationDateTime> - an element containing the date and
time this host was last modified.
o <iris:seeAlso> - an element containing <iris:entity> elements
specifying entities that are indirectly associated with this host.

Internet-Draft iris-dreg June 2003
3.2.5 <contact> Result
The <contact> element represents an instance of a contact
registration. The children of the <contact> element are as follows:
o <contactHandle> - a registry unique assigned identifier for this
contact.
o <commonName> - the name of the contact.
o <language> - a specification of the language code to use to
localize the data in this result.
o <organization> - an element containing the organization name of
the contact.
o <eMail> - elements containing the e-mail address for this contact.

contact.
o <createdDateTime> - an element containing the date and time this
contact was created.
o <lastModificationDateTime> - an element containing the date and
time this contact was last modified.
o <lastVerificationDateTime> - an element containing the date and

the appropriate registration authority.
Newton Expires December 29, 2003 [Page 12]
Internet-Draft iris-dreg June 2003
o <translatedContacts> - an element containing <iris:entity>
elements specifying equivalents of this result that have been
translated into other languages. The referents MUST be <contact>
(Section 3.2.5) results.
o <iris:seeAlso> - an element containing <iris:entity> elements
specifying entities that are indirectly associated with this
contact.
3.2.6 <registrationAuthority>
The <registrationAuthority> result represents an entity capable of
registering domains.
The <serviceInstance> child element of <registrationAuthority>
contains an <entity> element pointing to the entity "id" in the
entity class "service-definition". The authority areas found in the
referent MUST be domains and are the domains for which a given
registration authority has control.
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>).
3.3 Generic Code Derivatives
3.3.1 <searchTooWide>
Servers MAY use the <searchTooWide> error code when a query capable
of using one of the elements from the contact search group (Section
3.1.7) must be narrowed to yield a result set acceptable to the
policies of the server operator.
3.3.2 <languageNotSupported>
The queries <findDomainsByRegistrant>, <findDomainsByI18NName>, 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.

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 Expires December 29, 2003 [Page 37]
Internet-Draft iris-dreg June 2003
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 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 no records are found, then the left-most component of the
domain name is removed, and the first step is repeated again
(e.g. "com" ).
3. If all the components of the domain name are removed and no
records are found, then the DNS is queried for the A 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 leftmost component. This is
always '.'.
2. The IRIS [5] direct resolution process is tried on the domain
name.
3. If no records are found, then the original component to the right
Newton Expires December 29, 2003 [Page 38]
Internet-Draft iris-dreg June 2003
of the left-most component 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 components of the original domain are present and no
records are found, then the DNS is queried for the A records
corresponding to the original domain name and the port used is
the well-known port for the default protocol of IRIS.

7. Internationalization Considerations
Implementers should be aware of considerations for
internationalization in IRIS [5].
In addition, 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 in Unicode. Server
implementations should take care with normalization processes of
Unicode during searches. The <language> element is provided in
queries that have potential to traverse such data. Clients should
use these elements to indicate to the server the target languages
desired, and servers should use these elements to better enable
normalization and search processes.
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. The schema for this registry has been
designed so that clients need not interpret the content of elements
or attributes for localization.
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.

8. IANA Considerations
The following URN will need to be registered with IANA according to
the IANA considerations defined in IRIS [5]:
urn:ietf:params:xml:ns:dreg1
The following NAPSTR application service label will need to be
registered with IANA according to the IANA considerations defined in
IRIS [5]:
DREG1

9. Security Considerations
This document lays out no new considerations for security precautions
beyond that specified in IRIS [5].

Appendix A. Example Requests and Responses
The examples in this section use the string "C:" to denote data sent
by a client to a server and the string "S:" to denote data sent by a
server to a client.
A.1 Example 1
The following is an example of an entity lookup in a dreg1 registry
for the contact-handle of 'mak21'. The response shows the ability to
specify data as being withheld because it is private.

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.
