Subject: Re: [sca-assembly] NEW ISSUE: Abstract base type for Service and Reference
In the Tuscany model, we have used the noun "Contract" for this purpose. I think a noun is preferable to an adjective. Any other ideas? Simon Simon C. Nash, IBM Distinguished Engineer Member of the IBM Academy of Technology Tel. +44-1962-815156 Fax +44-1962-818999 "David DiFranco" <ddifranc@bea.com> 25/10/2007 15:00 To <sca-assembly@lists.oasis-open.org> cc Subject [sca-assembly] NEW ISSUE: Abstract base type for Service and Reference Title: Abstract base type for Service and Reference TARGET: Assembly spec DESCRIPTION: The XML schema definitions for Service and Reference contain an identical set of elements, and also share some attributes. It would be useful to have Service and Reference extend from a common base class. This would make it easier to deal with Services and References programmatically, when processing an SCA XML file, or working with code generated from the XML schema. PROPOSAL: New proposed schema content below. If someone can think of a better name for the base type than ?Bindable?, please suggest. <complexType name="Bindable" abstract="true"> <sequence> <element ref="sca:interface" minOccurs="0" maxOccurs="1" /> <element name="operation" type="sca:Operation" minOccurs="0" maxOccurs="unbounded" /> <choice minOccurs="0" maxOccurs="unbounded"> <element ref="sca:binding" /> <any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded" /> </choice> <element ref="sca:callback" minOccurs="0" maxOccurs="1" /> <any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded" /> </sequence> <attribute name="name" type="NCName" use="required" /> <attribute name="requires" type="sca:listOfQNames" use="optional" /> <attribute name="policySets" type="sca:listOfQNames" use="optional"/> <anyAttribute namespace="##any" processContents="lax" /> </complexType> <complexType name="Service"> <complexContent> <extension base="sca:Bindable"> <attribute name="promote" type="anyURI" use="required" /> </extension> </complexContent> </complexType> <complexType name="Reference"> <complexContent> <extension base="sca:Bindable"> <attribute name="target" type="sca:listOfAnyURIs" use= "optional"/> <attribute name="wiredByImpl" type="boolean" use="optional" default="false"/> <attribute name="multiplicity" type="sca:Multiplicity" use= "optional" default="1..1" /> <attribute name="promote" type="sca:listOfAnyURIs" use= "required" /> </extension> </complexContent> </complexType> Notice: This email message, together with any attachments, may contain information of BEA Systems, Inc., its subsidiaries and affiliated entities, that may be confidential, proprietary, copyrighted and/or legally privileged, and is intended solely for the use of the individual or entity named in this message.
