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)1.01.0, as described in XML[1],[1]; XML Schemanotationnotation, as described in XML_SD [3] and XML_SS[4],[4]; and XMLNamespacesNamespaces, as described in XML_NS [2]. Examples of client/server XML exchanges with this registry type are available in Appendix A. Newton & SanzExpiresStandards Track [Page 2] RFC 3982 IRIS-Dreg January11,2005[Page 3] Internet-Draft iris-dreg July 20042. 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 inRFC2119BCP 14, RFC 2119 [10].Newton & Sanz Expires January 11, 2005 [Page 4] Internet-Draft iris-dreg July 20043. Schema Description IRIS requires the derivation of both query and result elements by a registryschemas.schema. These descriptions follow. References to XML elementswith nowithout 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.Therefore, thisThis section will use terms defined by RFC 2119 [10] to describethe specification outside the scope of the formal XML syntax.these. While reading this section, please reference Section 4 for needed details on the formal XML syntax.3.13.1. Query Derivatives3.1.13.1.1. <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 toonlyregistrars 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 specifiesanequivalence to the registrar's name. If the <namePart> element is not present, the query MUST return all registrars applicable(i.e.(i.e., in consideration of <baseDomain>). This query MUST return a result set of zero or more <registrationAuthority> elements. See Section 3.2.5.3.1.2Newton & Sanz Standards Track [Page 3] RFC 3982 IRIS-Dreg January 2005 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 domainsonlyunderneath the domain specified by itscontentcontent, if it is present.Newton & Sanz Expires January 11, 2005 [Page 5] Internet-Draft iris-dreg July 2004The 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 allowsforthe domains to be selected based on the contact having the specified contact handle. The query MAY also be constrained further by 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 togive ahint 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.3.1.33.1.3. <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.3.1.43.1.4. <findDomainsByIDN> Query This query differs from the <findDomainsByName> query by allowing the scope of the query to takeinto considerationinternationalized domainnames.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) (whichis toonlyreturnreturns 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 togive ahint 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.3.1.53.1.5. <findContacts> Query <findContacts> searches for contacts given search constraints.Newton & Sanz Expires January 11, 2005 [Page 6] Internet-Draft iris-dreg July 2004The 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 togive ahint 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.3.1.63.1.6. <findDomainsByHost> 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.3.1.73.1.7. 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 caneitherconstrain the query either by an exact match using the <exactMatch> element, orit may constrain the queryby 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> element MUST only contain a valid domain name(i.e. no(i.e., without an '@' symbol), and the matching SHOULD take place only on the domain given(i.e.(i.e., no partial matches with respect to substrings or parent domains). If either the contents of the <inDomain> element or the 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]. Newton & Sanz Standards Track [Page 5] RFC 3982 IRIS-Dreg January 2005 The <city>, <region>, and <postalCode> elements restrict the scope of the query based on the city, region, or postal code of the contact, respectively. Eachonemust only contain an <exactMatch> element containing the exact city, region, or postal code(i.e.(i.e., no substring searches).Newton & Sanz Expires January 11, 2005 [Page 7] Internet-Draft iris-dreg July 2004 3.23.2. Result Derivatives3.2.13.2.1. 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"--- containsanthe optional element of<appliedDate><appliedDate>, indicating the date and time when the status wasappliedapplied, andanthe optional element of <description> with the required attribute'language''language', indicating a description of the status. This element also hasanthe optional attributeof 'scope' to indicate'scope', indicating the scope or origin of the status value. o "contactTypeType"--- containsanoptional <description> child elements. Each <description> child element requires a 'language' attribute. As specified,they are nillablethese 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-- 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-- If true, this specifies that the content is absent because policy does not allow it to be givenunderat 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-- If true, this specifies that the content is not to be redistributed. o 'specialAccess'- if-- 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 accessbeinggranted to therecepientrecipient of the data. For example,Newton & Sanz Expires January 11, 2005 [Page 8] Internet-Draft iris-dreg July 2004marking 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 viewingofthat 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.3.2.23.2.2. <domain> Result An example of a <domain> result: <domain authority="iana.org" registryType="dreg1" entityClass="domain-handle" entityName="example-com-1"> <domainName>example.com</domainName> <domainHandle>tcs-com-1</domainHandle> <nameServer iris:referentType="host" authority="iana.org" registryType="dreg1" entityClass="host-handle" entityName="research7" /> <nameServer iris:referentType="host" authority="iana.org" registryType="dreg1" entityClass="host-handle" entityName="nsol184" /> <registry iris:referentType="registrationAuthority" authority="com" registryType="dreg1" entityClass="contact-handle" entityName="VGRS" /> <registrar iris:referentType="registrationAuthority" authority="iana.org" registryType="dreg1" entityClass="contact-handle" entityName="dbarton" /> Newton & Sanz Standards Track [Page 7] RFC 3982 IRIS-Dreg January 2005 <initialDelegationDateTime xsi:nil="true"/> </domain> The <domain> result represents an instance of a domain assignment.

If a client passes to the server a languagewhichthat 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 elementsspecifyspecifies 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.3.43.4.

iris-dreg July 20045. BEEP Transport Compliance IRIS allows several extensions of the core capabilities. This section outlinesthoseextensions allowable by IRIS-BEEP [6].5.15.1. Message Pattern This registry type uses the default message patternasdescribed in IRIS-BEEP [6].5.25.2. Server Authentication This registry type only uses the basic TLS server authenticationmethodmethod, as described in IRIS-BEEP [6].Newton & Sanz Expires January 11, 2005 [Page 38] Internet-Draft iris-dreg July 20046. URI Resolution6.16.1. 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 registrytype,type: urn:ietf:params:xml:ns:dreg1.6.2Newton & 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 thedirect-resolutiondirect- resolution method if the authority is only a domain name(i.e.(i.e., without the port number). The process for this condition is as follows: 1. The IRIS [5]direct resolutiondirect-resolution process is tried on the domain name(e.g. "example.com" ).(e.g., "example.com"). 2. If thedirect resolutiondirect-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" ).(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 domainnamename, and the port used is the well-known port for the default protocol of IRIS.6.36.3. Top-Down Resolution The top-down alternative resolution method MUST be identified as 'top' in IRISURI's.URIs. The process for this resolution method differs from thedirect-resolutiondirect- resolution method if the authority is only a domain name(i.e.(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 resolutiondirect-resolution process is tried on the domain name. 3. If thedirect resolutiondirect-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.(e.g., if"."".", then"com","com"; if"com""com", then "example.com").Newton & Sanz Expires January 11, 2005 [Page 39] Internet-Draft iris-dreg July 20044. 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 domainnamename, and the port used is the well-known port for the default protocol of IRIS. Newton & SanzExpiresStandards Track [Page 37] RFC 3982 IRIS-Dreg January11,2005[Page 40] Internet-Draft iris-dreg July 20047. 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 benon-ASCII,non-ASCII and could contain virtually any Unicode character. The <language> element is provided in queries that have the potential to traverse such data. Clients should usethese elementsthis element to indicateto the server ofthe desired target languagesdesired,to the server, and servers should usethese elementsthis element to better enable normalization and search processes (see [18]).ClientsFor clients needing to localize the data tags in thisprotocol should takeprotocol, 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 thanthosethat of 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 by using the 'Z' indicator for Coordinated Universal Time (UTC).Newton & Sanz Expires January 11, 2005 [Page 41] Internet-Draft iris-dreg July 20048. IANA Considerations8.18.1. 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 48.2Newton & Sanz Standards Track [Page 38] RFC 3982 IRIS-Dreg January 2005 8.2. S-NAPTR Registration The following S-NAPTR application service labelwill need to behas been registered with IANA according to the IANA considerations defined in IRIS [5]: DREG18.38.3. BEEP Registration The following BEEP Profile URIis to be registeriedhas been registered with IANA, in addition to the registration provided in IRIS-BEEP [6]. http://iana.org/beep/iris1/dreg1Newton & Sanz Expires January 11, 2005 [Page 42] Internet-Draft iris-dreg July 20049. Security Considerations This document lays out no new considerations for security precautions beyond that specified in IRIS [5].Newton & Sanz Expires January 11, 2005 [Page 43] Internet-Draft iris-dreg July 200410.

Acknowledgements Many of the concepts concerning the use of SRV records for step-wise refinementtowardstoward finding authoritative servers and many of the details of result objects in thisdraftdocument 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 Blackagavemade many technical contributionsdue to workbased on his work on IRIS implementation and his experiencedjudgement.judgment. He also contributed many editorial clarifications.
