20、 of RepresentativeNational Institute of Standards The ABNF rule “service: URL“ defined in RFC2609 defines the format of service: URLs ; and its grammar provides the basis for the following refining ABNF rules: service-type = abstract-type “:“ url-scheme ; Restricted to abstract service types only. a

21、bstract-type = “wbem“ url-scheme = resname ; The value shall be a valid URL scheme for the WBEM ; protocols registered for this service location. For ; example, “http“ or “https“ for CIM-XML or WS-Management, ; and “telnet“ or “ssh“ for SM-CLP. sap = site ; Restricted to not allow url-part. site = i

22、psite ; Restricted to IP sites only. ipsite = “/“ hostport ; Restricted to not allow “user“ and to require hostport. hostport = host “:“ port ; Restricted to require port. host = hostnumber ; Restricted to numbered addresses only (no host names). hostnumber = ipv4-number / ipv6-number ; Extended to

23、also allow IPV6 addresses. ipv6-number = “ ipv6-address “ ; Using the common syntax. ; Definition of IPV6 address syntax, for additional restrictions see RFC4291: ipv6-address = ipv6-hexpart “:“ ipv4-number ipv6-hexpart = ipv6-hexseq / ipv6-hexseq “:“ ipv6-hexseq ipv6-hexseq = 1*4HEXDIGIT *( “:“ 1*4

24、HEXDIGIT ) ; Examples of service: URLs using this syntax: ; “service:wbem:http:/192.168.0.1:5988“ ; “service:wbem:https:/fe80:200:f8ff:fe21:67cf:5989“ This attribute is optional to be registered. When registered, the value of this attribute shall be the ABNF grammar string specified above. Version 1

25、.0 of this template used this attribute to register a portion of the service: INCITS 531-2013 8 URL. This enabled SLP User Agents to determine the service location from the value of this attribute, or from the value of the service: URL. With version 2.0 of this template, SLP User Agents need to dete

26、rmine the service location from the value of the service: URL only. service-hi-name=string O The value of this attribute shall be the value of the ElementName property of the CIM_ObjectManager instance representing the WBEM server that is registered. A value of NULL in that property shall be represe

27、nted by omitting this attribute. (This is why it is defined as optional (O).) The value of this attribute can be used in any human interfaces as the name of that WBEM server. service-hi-description=string O The value of this attribute shall be the value of the Description property of the CIM_ObjectM

28、anager instance representing the WBEM server that is registered. A value of NULL in that property shall be represented by omitting this attribute. (This is why it is defined as optional (O).) The value of this attribute can be used in any human interfaces as a description of that WBEM server. servic

29、e-id=string L The value of this attribute shall be the value of the Name property of the CIM_ObjectManager instance representing the WBEM server that is registered. The value of this attribute can be used as a programmatic identification of that WBEM server within the host offering that service. Com

30、municationMechanisms=string L M The set of values of this multi-valued attribute shall be the values of the CommunicationMechanism property of those CIM_ObjectManagerCommunicationMechanism instances that represent the WBEM protocols supported by the service access point identified by the service: UR

31、L. Each value can be used as a programmatic identification of the WBEM protocol that is supported. For a description of these values, see the definition of that property in the CIM Schema. “Unknown“, “Other“, “CIM-XML“, “WS-Management“, “SM-CLP“ OtherCommunicationMechanisms=string L M O This attribu

32、te shall be registered only if any of the CommunicationMechanisms attribute values has a value of “Other“. If registered, the following applies: The values of this multi-valued attribute shall be index-correlated with the values of the CommunicationMechanisms attribute, such that values at the same

33、index represent the same WBEM protocol. Values at indexes for which the corresponding value of the CommunicationMechanisms attribute is “Other“ shall be the value of the OtherCommunicationMechanismDescription property of the CIM_ObjectManagerCommunicationMechanism instance representing the WBEM prot

34、ocol for that index. Property values of NULL shall be represented by an empty string. Values at indexes for which the corresponding value of the CommunicationMechanisms attribute is not “Other“ shall be an empty string. These values can be used as a programmatic identification of the WBEM protocols

35、that are supported, in case the CommunicationMechanism attribute value is “Other“. The CIM Schema defines this property to contain free-form strings; other specifications (such as management initiative wrapper specifications) may define additional constraints on the values. CommunicationMechanismsVe

36、rsion=string L M The values of this multi-valued attribute shall be index-correlated with the values of the CommunicationMechanisms attribute, such that values at the same index represent the same WBEM protocol. The value of this attribute at any index shall be the value of the Version property of t

37、he CIM_ObjectManagerCommunicationMechanism instance representing the WBEM protocol for that index, if that property is non-NULL. A property value of NULL shall be represented by an empty string. AuthenticationMechanisms=string L M INCITS 531-2013 9 The set of values of this multi-valued attribute sh

38、all be the unique set of values of the array entries of the AuthenticationMechanismsSupported array property of the CIM_ObjectManagerCommunicationMechanism instances representing the WBEM protocols supported by the service access point identified by the service: URL. In other words, the set of value

39、s represents the superset of all authentication mechanisms supported by these WBEM protocols, without correlating any authentication mechanism to the WBEM protocol or protocols supporting it. A WBEM client needs to try the desired authentication mechanism with the desired WBEM protocol to see whethe

40、r it is available. For a description of these values, see the definition of that property in the CIM Schema. “Unknown“, “None“, “Other“, “Basic“, “Digest“ OtherAuthenticationMechanisms=string L M O This attribute shall be registered only if any of the AuthenticationMechanisms attribute values has a

41、value of “Other“. If registered, the following applies: The values of this multi-valued attribute shall be index-correlated with the values of the AuthenticationMechanisms attribute, such that values at the same index represent the same authentication mechanism. Values at indexes for which the corre

42、sponding value of the AuthenticationMechanisms attribute is “Other“ shall be the value of the AuthenticationMechanismDescriptions property of the CIM_ObjectManagerCommunicationMechanism instance representing the authentication mechanism for that index. Property values of NULL shall be represented by

43、 an empty string. Values at indexes for which the corresponding value of the AuthenticationMechanisms attribute is not “Other“ shall be an empty string. The CIM Schema defines this property to contain free-form strings; other specifications (such as management initiative wrapper specifications) may

44、define additional constraints on the values. InteropNamespaces=string L M This multi-valued attribute shall have one value for each distinct major version of the CIM Schema supported by the WBEM server that is registered. Each attribute value shall be the name of the Interop namespace for that major

45、 CIM Schema version. For a definition of the concept of an Interop namespace, see DSP1033. The name of a namespace can be found in the Name property of the CIM_Namespace instance representing the namespace. Namespaces=string L M O If this multi-valued attribute is registered, it shall have one value

46、 for each distinct CIM namespace supported by the WBEM server that is registered. Each attribute value shall be the name of the namespace. The name of a namespace can be found in the Name property of the CIM_Namespace instance representing the namespace. The set of distinct namespaces (of a given ma

47、jor CIM Schema version) supported by a WBEM server is represented as instances of CIM_Namespace in the Interop namespace of the WBEM server. InitiativesSupported=string L M O If this multi-valued attribute is registered, it shall have one value for each management initiative that is implemented by t

48、he WBEM server such that it conforms to the implementation requirements specification of the management initiative. Each attribute value shall have the following format (expressed in ABNF): registered-org “:“ registered-name Where: registered-org shall identify the business entity owning the impleme

49、ntation requirements specification of the management initiative. The registered-org value shall include a copyrighted, trademarked, or otherwise unique name that is owned by that business entity or that is a registered ID assigned to that business entity by a recognized global authority. In addition, to ensure uniqueness, the registered-org value shall not contain a colon (:). For implementation requirements specifications owned by DMTF, the value shall be “DMTF“. registere
