The presentation shows a first version of a Domain Specific Language (DSL) based on Eclipse XText, the tooling provided with it and the way to generate the necessary XSD and WSDL artifacts.

16. But wouldn't it be easier .... use a DSL for WSDL Using Domain Specific Language (s) to Simplify Creating SOA Artifacts <wsdl:definitions xmlns:tns=&quot;http://trivadis.com/service/credit-card/v1&quot; ... name=&quot;CreditCardValidation-v1&quot;> <wsdl:types> <xsd:schema ...> </wsdl:types> <wsdl:message name=&quot;validateCardRequest&quot;> <wsdl:part name=&quot;request&quot; element=&quot;tns:validateCreditCardPaymentRequest&quot;/> </wsdl:message> <wsdl:message name=&quot;validateCardResponse&quot;> <wsdl:part name=&quot;reply&quot; element=&quot;tns:validateCreditCardPaymentResponse&quot;/> </wsdl:message> <wsdl:message name=&quot;invalidCreditCardNumberFault&quot;> <wsdl:part name=&quot;error„ element=&quot;tns:invalidCreditCardNumberFault&quot;/> </wsdl:message> <wsdl:portType name=&quot;CreditCardValidationPT&quot;> <wsdl:operation name=&quot;validateCard&quot;> <wsdl:input message=&quot;tns:validateCardRequest&quot;/> <wsdl:output message=&quot;tns:validateCardResponse&quot;/> <wsdl:fault name=&quot;InvalidCreditCardNumberFault&quot; message=&quot;tns:invalidCreditCardNumberFault&quot;/> </wsdl:operation> </wsdl:portType> <wsdl:binding ...> <wsdl:service ...> </wsdl:definitions> abstract message common { requestNr : String [1:1] } Import common.msgtype namespace service.credit-card(1.0) using cdm.credit-card(1.0) as cc message validateCardRequest extends common { creditCard : cc.CreditCard forAmount : Double } message validateCardResponse { requestNr : String[1:1] reservationNumber : String } fault invalidCreditCardNumber { code : String creditCard : cc.CreditCard } service CreditCardValidation { sync operation validateCard throws invalidCreditCardNumber input validateCardRequest output validateCardResponse }

17. ... and for the XSD‘s .... Using Domain Specific Language (s) to Simplify Creating SOA Artifacts namespace cdm.credit-card(1.0) entity CreditCard { id : Integer creditCardKind : CreditCardKind [1:1] cardNumber : String [1:1] cardholderFirstName : String cardholderLastName : String [1:1] expirationMonth : Month [1:1] expirationYear : Year [1:1] } dataType Month extends Integer pattern &quot;[0-1][0-9]&quot; dataType Year extends Integer pattern &quot;[0-9][0-9][0-9][0-9]&quot; dataType CrediCardKind extends String enum { &quot;visa&quot;, &quot;mastercard&quot;, &quot;amexco&quot; } <xs:schema xmlns:xs=„...&quot; xmlns:tns=&quot;http://www.trivadis.com/cdm/credit-card/v1&quot; targetNamespace= „http://www.trivadis.com/cdm/credit-card/v1 “ elementFormDefault=&quot;qualified&quot; attributeFormDefault=&quot;unqualified&quot; version=&quot;1.0&quot;> <xs:element name=&quot;creditCard&quot; type=&quot;tns:CreditCardT&quot;/> <xs:complexType name=&quot;CreditCardT&quot;> <xs:sequence> <xs:element name=&quot;creditCardKind&quot; type=&quot;tns:CreditCardKindT&quot;/> <xs:element name=&quot;cardNumber&quot; type=&quot;xs:string&quot;/> <xs:element name=&quot;cardholderFirstName&quot; type=&quot;xs:string&quot; minOccurs=&quot;0&quot;/> <xs:element name=&quot;cardholderLastName&quot; type=&quot;xs:string&quot;/> <xs:element name=&quot;expirationMonth&quot; type=&quot;tns:MonthT&quot;/> <xs:element name=&quot;expirationYear&quot; type=&quot;tns:YearT&quot;/> </xs:sequence> <xs:attribute name=&quot;id&quot; type=&quot;xs:int&quot;/> </xs:complexType> <xs:simpleType name=&quot;CreditCardKindT&quot;> <xs:restriction base=&quot;xs:string&quot;> <xs:enumeration value=&quot;visa&quot;/> <xs:enumeration value=&quot;mastercard&quot;/> <xs:enumeration value=&quot;amexco&quot;/> </xs:restriction> </xs:simpleType> ... /xs:schema>
