Introduction This document describes an IRIS registry schema for registries of ENUM data using an XML Schema [4] derived from and using the IRIS [5] schema. 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]. Newton Expires March 13, 2006 [Page 3] Internet-Draft iris-ereg September 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 RFC2119 [10]. This document uses the term "ENUM" as the fully qualified domain name following the conventions of ENUM [18]. Newton Expires March 13, 2006 [Page 4] Internet-Draft iris-ereg September 2005 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 Query finds ENUM domains by searching on prefixes of E.164 numbers and returns (Section 3.2.3) results. The E.164 prefix is specified using the child of . An optional child element of , , can narrow the search to ENUM domains associated with E.164 numbers that are either more specific or less specific. If the element is present and has the content 'less', then the search is to be narrowed to E.164 numbers that are less specific (i.e. have fewer digits). If the element is present and has the content 'more', then the search is to be narrowed to E.164 numbers that are more specific (i.e. have more digits). 3.1.2 Query finds ENUM domains by searches on fields associated with an ENUM domain's contact. The allowable search fields are handled with either the element or one of the elements in the "contactSearchGroup" (see Section 3.1.5). The element allows for the ENUM domains to be selected based on the contact having the specified contact handle. The query MAY also be constrained further using the optional Newton Expires March 13, 2006 [Page 5] Internet-Draft iris-ereg September 2005 element. The contents of this element signify the role the contact has with the ENUM domain. This query also provides optional 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 Query searches for contacts given search constraints. The allowable search fields are handled by one of the elements in the "contactSearchGroup" (see Section 3.1.5). This query also provides optional 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. 3.1.4 Query This query does a simple search for the ENUM domainss 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. 3.1.5 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 either constrain the query by an exact match using the element, or it may constrain the query 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 MUST only contain a valid domain Newton Expires March 13, 2006 [Page 6] Internet-Draft iris-ereg September 2005 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 element or 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 [16]. The , , and 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 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 "enumStatusType" - describes a state for an ENUM domain. This element has the following optional attributes: * 'scope' - Indicates the scope or origin of the status value. * 'disposition' - Contains either the value "pending", meaning that initial processing for this status has begun and is not yet complete, or the value "prohibited", meaning this ENUM domain cannot achieve this status according to either the registry or registrar of this ENUM domain. * 'actor' - Contains either the value "registry", meaning this status value has been associated with this ENUM domain by the Newton Expires March 13, 2006 [Page 7] Internet-Draft iris-ereg September 2005 registry, or the value "registrar", meaning this status value has been associated with this ENUM domain by the registrar. This element has the following optional child elements: * - Indicates the date and time the status was applied. * - Provides a textual description of the status. This element has a required 'language' attribute. * - Indicates a jurisdictional-dependent reason for this status value. This element has a required 'authority' attribute to indicate the jurisdicational authority associated with this sub-status. o "contactTypeType" - contains an optional child elements. Each 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. 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. 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. 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 being granted the recepient 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 of that particular data. Likewise, data marked with Newton Expires March 13, 2006 [Page 8] Internet-Draft iris-ereg September 2005 'doNotRedistribute' or 'specialAccess' is to be expected if the user is authenticated and has a high level of access. 3.2.2 Contact Group Many of the results share a set of references to contacts regarding an associated role. These are represented by the following elements: o o o o o o o o Each of these elements contain an entity reference. The referent of each MUST be a (Section 3.2.5). 3.2.3 Result An example of a result: +1 7035 555 1212 Bill Eckels Mark Kosters AUTO-LOCK AUTO-LOCK AUTO-LOCK Newton Expires March 13, 2006 [Page 10] Internet-Draft iris-ereg September 2005 STANDARD RGP The result represents an instance of an ENUM domain assignment. The children of the element are as follows: o - the E.164 number for this ENUM domain as defined by [13].

Any one status value MUST NOT imply other status values. For instance, is just an indicatation that the ENUM domain is given special reserved status; the status value must also be present to indicate that the ENUM domain cannot be registrered. o - an element containing an entity reference, the referent of which MUST be an (Section 3.2.3).

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 . 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 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 3.2.4) in the response. o host-handle - the registry unique identifier given a nameserver. It yields a (Section 3.2.4) in the response. o e164 - an E.164 number as specified by [13]. It yields a (Section 3.2.3) in the response. Clients SHOULD remove all non- digit characters between the digits of an E.164 number, and servers MUST ignore any non-digit characters between the digits of an E.164 number. (e.g. "+1 703 555 1212" is to be interpretted as "+17035551212"). o enum - the fully qualified name of an ENUM domain. This is a domain name as specified by RFC 1035 [9]. It yields a (Section 3.2.3) in the response. o enum-handle - the registry unique identifier given a ENUM domain. It yields a (Section 3.2.3) in the response. Newton Expires March 13, 2006 [Page 21] Internet-Draft iris-ereg September 2005 o contact-handle - the registry unique identifier given a contact. It yields a (Section 3.2.5) in the response. o ipv4-address - the IPv4 address of a nameserver. It yields a (Section 3.2.4) in the response. o ipv6-address - the IPv6 address of a nameserver. It yields a (Section 3.2.4) in the response. o registration-authority - the name of a registration authority. It yields a (Section 3.2.6) in the response. o validation-entity - the name of an validation entity. It yields a (Section 3.2.7) o csp - the identifier of a communication service provider. Yields a (Section 3.2.8). o validation-event - the identifier for a validation event. It yields a (Section 3.2.9). o All names in these entity classes are case insensitive.

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 only uses the basic TLS server authentication method as described in IRIS-BEEP [6]. Newton Expires March 13, 2006 [Page 49] Internet-Draft iris-ereg September 2005 6. URI Resolution 6.1 Application Service Label The application service label associated with this registry type MUST be "EREG1". This is the abbreviated form of the URN for this registry type, urn:ietf:params:xml:ns:ereg1. Newton Expires March 13, 2006 [Page 50] Internet-Draft iris-ereg September 2005 7. Internationalization Considerations Implementers should be aware of considerations for internationalization in IRIS [5]. The social data associated with contacts may be non-ASCII, and could contain virtually any Unicode character. The 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 ). 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 elements provided in many of the results.
