  1. The XML to TTCN-3 Mapping Contact: Ina Schieferdecker, schieferdecker@fokus.fraunhofer.de, +49 30 3463 7241

  2. Mapping XML to TTCN-3 • Map element tags and attributes to TTCN-3 fields and types • Different mappings • Embedded approach • Flat-Catalog approach • Named Type approach

  3. Mapping Schemas in Embedded Approach <schema>     <element name="weather">        <complexType>           <sequence>              <element name="location">                   <complexType >                   <sequence>                       <simpleType name="city">                          <restriction base="string">                             <pattern value="[a-zA-Z]"/>                          </restriction>                       </simpleType>                        <element name="country" type="string"/>                    </sequence>                  </complexType>              </element>              <element name="temperature" type="integer"/>              <element name="barometric_pressure" type="integer"/>              <element name="conditions" type="string"/>            </sequence>        </complexType>     </element> </schema> XML Schema typerecordweatherType { locationTypelocation, integertemperature, integerbarometric_pressure, charstringconditions } typerecordlocationType { charstringcity ("a".."z","A".."Z"), charstringcountry } TTCN-3 Types

  4. Mapping Schemas in Flat Catalog Approach <schema> <element name="temperature" type="integer"/> <element name="barometric_pressure" type="integer"/> <element name="conditions" type="string"/> <element name="country" type="string"/> <simpleType name="city"> <restriction base="string"> <pattern value="[a-zA-Z]"/> </restriction> </simpleType> <element name="location"> <complexType > <sequence> <element ref="city"/> <element ref="country"/> </sequence> </complexType> </element> <element name="weather"> <complexType> <sequence> <element ref="location"/> <element ref="temperature"/> <element ref="barometric_pressure"/> <element ref="conditions"/> </sequence> </complexType> </element> </schema> XML Schema TTCN-3 Types typeintegertemperatureType; typeintegerbarometric_pressureType; typecharstringconditionsType; typecharstringcountryType; typecharstringcityType ("a".."z","A".."Z"); typerecordlocationType { cityTypecity, countryTypecountry } typerecordweatherType { locationTypelocation, temperatureTypetemperature, barometric_pressureTypebarometric_pressure, conditionsTypeconditions }

  5. Mapping Schemas in Named Type Approach <schema> <complexType name="weatherType" > <sequence> <element name="location" type="locationType"/> <element name="temperature" type="integer"/> <element name="barometric_pressure" type="integer"/> <element name="conditions" type="string"/> </sequence> </complexType> <complexType name="locationType" > <sequence> <element name="city" type="cityType"/> <element name="country" type="string"/> </sequence> </complexType> <simpleType name="cityType"> <restriction base="string"> <pattern value="[a-zA-Z]"/> </restriction> </simpleType> <element name="weather" type="weatherType"/> </schema> XML Schema TTCN-3 Types typerecord weatherType { locationType location, integer temperature, integer barometric_pressure, charstring conditions } typerecord locationType { cityType city, countryType country } typecharstring cityType ("a".."z","A".."Z");
