10、 standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fie
11、lds of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted
12、in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an Internati
13、onal Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Amend

The REL (Rights Expressi
16、on Language) defined in the previous clauses and Annexes A through J is a comprehensive, flexible and domain-agnostic rights language that can be used for a wide spectrum of applications. However, in order to meet specific needs on the REL from, for example, an ecosystem (e.g., electronic books or m
17、obile devices), an application (e.g., media streaming), a function (e.g., certificating and attesting assertions), or a region (e.g., North America, Europe or Asia), the entire REL may need to be restricted to some profiles for the purposes of optimization and interoperability in developing and depl
18、oying systems, applications, components and devices. Here, a profile here represents a subset of the REL types, elements and attributes (with any specified syntactic, semantic and processing restrictions), possibly together with some further extensions to the REL types and some newly introduced elem
19、ents and attributes, all subject to maintaining compliance to the specification of the REL. 10.2 Multimedia Extension One 10.2.1 General This subclause specifies an additional extension, called the “multimedia extension one”, of the REL specified in the previous clauses. 10.2.2 Normative Namespace T
20、he XML namespace for the extension types and new elements and attributes introduced in the REL multimedia extension one shall be urn:mpeg:mpeg21:2005:01-REL-M1X-NS, and this namespace is normative. Here, the 01 represents a serial number that is expected to change as this extension evolves. Amendmen

The actual prefix used is not important as long as the names
22、pace URI is correct. The prefixes used in this extension are given in Table AMD1.1. Table AMD1.1 Prefixes of XML Schemas 10.2.4 Defintion of Multimedia Extension One This subclause defines the multimedia extension one to the REL. The syntax and the semantics of the types and elements in the multimed
23、ia extension one are presented here. The XML schema for the extension elements and types is listed in Annex L. 10.2.4.1 Principal Extension Elements 10.2.4.1.1 IdentityHolder 10.2.4.1.1.1 Informative Description The m1x:identityHolder element is an extension element of the type r:Principal defined i
24、n the REL Core. It identifies the principal who is the holder of the specified identity possibly in some identification system. The optional m1x:idSystem child element of the xsd:anyURI type is used to indicate the identification system. The m1x:idValue child element, which can be either character c
25、ontent or element content from any namespace, is used to contain the identifier value of the identity.

27、 m1x:identityHolder Principal The following example specifies a principal as the holder of an International Mobile Subscriber Identifier. urn:acme:imsi IMSI:2232111123 In the above example, the principal identified by m1x:identityHolder is granted the right to play the resource specified in r:digita
28、lResource. The types of the m1x:identityHolder element and the m1x:idValue child element are defined as extensions of the r:LicensePart type. Consequently, both m1x:identityHolder and m1x:idValue can be specified by variables. The following example is like the example above, except the principal is
29、a holder of any, instead of a particular, International Mobile Subscriber Identifier. urn:acme:imsi 10.2.4.1.1.2 Normative Specification Let p be a m1x:IdentityHolder. If p/m1x:idValue has a child element, then p/m1x:idValue identifies that system entity that possesses the identifier indicated by th
30、at child element. Otherwise, p/m1x:idValue identifies that system entity that possesses the identifier indicated by the value of p/m1x:idValue. In either case, the identifier belongs to the identification system indicated by the URI value of p/m1x:idSystem when the p/m1x:idSystem child element is pr

32、t in certain rights being associated to the copied resource. The optional attribute m1x:governanceRule of type QName indicates the name of a governance rule that determines how exactly the copy should be made and what rights should be associated and by whom for the copied resource. When the attribut
33、e is not specified, this right allows to make a bit-wise identical copy of the resource and to result in an identical copy of the r:license that this right is specified being made to the copied resource. This right can be used for copying the resource that is either locally available or received fro
34、m a remote location (e.g., via streaming or broadcasting) during the time this right is being exercised. Figure AMD1.2 m1x:governedCopy Right A sample code fragment is provided below for illustration: In the above example, any principal is granted the right to play a movie clip, and the right to cop

In this case, exercising the right m1x:governedCopy in the license will result in a bit-wise identical copy o

Then, if r/m1x:governanceRule is present, r identifies the act of making a copy and associating right expressions with that copy in compliance with the complianc
38、e rules identified by r/m1x:governanceRule. Otherwise, if r/m1x:governanceRule is absent, r identifies the act of making a bit-wise identical copy and associating a right expression to that copy that is Equal to the License in the authorizer in one of the authorization proofs for the authorization r
39、equest for that copy. If r is used as the Right Member of an authorization request, then the Resource Member of that authorization request shall be present and shall identify the resource being copied. 10.2.4.2.2 GovernedMove 10.2.4.2.2.1 Informative Description This element represents the right to
40、move the resource and at the same time to result in certain rights being associated to the moved resource. The moved resource and its associated rights should not exist or be valid on the original repository after exercising this right. The optional attribute m1x:governanceRule of type QName indicat
41、es the name of a governance rule that determines how exactly the resource should be moved and what rights should be associated and by whom for the moved resource. When the attribute is not specified, this right allows to the moved resource to be a bit-wise identical copy of the resource and to resul
42、t in an identical copy of the r:license that this right is specified being made to the moved resource. This right can be used for moving the resource that is either locally available or received from a remote location during the time this right is being exercised. Amendment 1:2007 toCAN/CSA-ISO/IEC
