738 ITU‐T's Technical Reports and Specifications subset of XAS. XAS and XAR differ because XAR does not contain data as contents. All transactions in this infrastructure utilize the XAS and its subset, XAR. XAS is designed according to Extensible Markup Language (XML). Figure 8.4.2 lists an example of D‐XAS. It includes the information to enable anonymization, including combinations of the sensitive attribute names and quasi‐identifiers, permitted anonymization methods and levels, and data attributes such as created date, updated date and history, ownership, copyrights, comments, and others. Figure 8.4.3 lists an example of a P‐XAR. It does not contain raw data; it only declares the required anonymization methods and levels. To enable masking or generalization processes, it can define the delimiter for distinguishing data sections. In this example, \"BirthDay\" is split utilizing the '‐' character. During the anonymizing process, the character is used to define the generalization boundary. If the data employs a general and standardized format, for example, BirthDay should be separated by '‐' it can generalize the data entry by referring to the default rule. As an additional feature, the data provider may publish data samples without data publishing limits to publicize the data's availability. This open information is termed \"open attribute.\" This open attribute can be declared in the data entry. 1 <?xml version=\"1.0\" encoding=\"utf‐8\"?> 2 <?xml‐anonymize type=\"text/xas\" href=\"p‐xar.xas\"?> 3 <list> 4 <rdf:RDF xmlns:rdf=\"http://www.w3.org/1999/02/22‐rdf‐syntax‐ns#\" xmlns:v=\"http://www.w3.org/2006/vcard/ns#\"> 5 <v:Kind rdf:about = \"http://foo.com/me/hogehoge\"> 6 <v:fn>Hoge Foo</v:fn> 7 <v:bday>1980‐01‐01</v:bday> 8 <v:hasTelephone> 9 <rdf:Description> 10 <rdf:value>+81‐45‐566‐1454</rdf:value> 11 <rdf:type rdf:resource=\"http://www.w3.org/2006/vcard/ns#Work\"/> 12 <rdf:type rdf:resource=\"http://www.w3.org/2006/vcard/ns#Voice\"/> 13 </rdf:Description> 14 </v:hasTelephone> 15 <v:hasAddress> 16 <rdf:Description> 17 <v:street‐address>123‐45 Hoge Village</v:street‐address> 18 <v:locality>FooCity</v:locality> 19 <v:postal‐code>5555</v:postal‐code> 20 <v:country‐name>Japan</v:country‐name> 21 </rdf:Description> 22 </v:hasAddress> 23 </v:Kind> 24 </rdf:RDF> 25 <OfficeScale>100ha</OfficeScale> 26 <PowerConsumption>10kWh</PowerConsumption> 27 28 <rdf:RDF xmlns:rdf=\"http://www.w3.org/1999/02/22‐rdf‐syntax‐ns#\" xmlns:v=\"http://www.w3.org/2006/vcard/ns#\"> 29 <v:Kind rdf:about = \"http://foo.com/me/db\"> Fig. 8.4.2 D‐XAS Example (Extract)
