• XPDL 2.1 Proposals

Icon

|Please note: this is a preliminary proposal for XPDL 2.1 which has not yet been adopted by the coalition. Please use this page for discussion of that proposed extension. This proposal may change substantially before adoption, or may possibly never be officially adopted in this form.

We want to add the ability to specify icons to appear in the interior of nodes, typcally activity nodes. The changed schema for NodeGraphicsInfo is:

<xsd:element name="NodeGraphicsInfo">
		<xsd:complexType>
			<xsd:sequence>
				<xsd:element ref="xpdl:Coordinates" minOccurs="0"/>
				<xsd:element ref="xpdl:Icon" minOccurs="0"/>
				<xsd:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>
			</xsd:sequence>
			<xsd:attribute name="ToolId" type="xsd:string" use="optional"/>
			<xsd:attribute name="IsVisible" type="xsd:boolean" use="optional" default="true"/>
			<xsd:attribute name="Page" type="xsd:NMTOKEN" use="optional"/>
			<xsd:attribute name="LaneId" type="xsd:NMTOKEN" use="optional"/>
			<xsd:attribute name="Height" type="xsd:double" use="optional"/>
			<xsd:attribute name="Width" type="xsd:double" use="optional"/>
			<xsd:attribute name="BorderColor" type="xsd:string" use="optional"/>
			<xsd:attribute name="FillColor" type="xsd:string" use="optional"/>
			<xsd:attribute name="Shape" type="xsd:string" use="optional"/>
			<xsd:anyAttribute namespace="##other" processContents="lax"/>
		</xsd:complexType>
	</xsd:element>

where we have added an optional element "Icon". The new schema for Icon is

	<xsd:element name="Icon">
                        <xsd:attribute name="icon" type="xsd:hRef" use="required"/>
			<xsd:attribute name="Height" type="xsd:double" use="optional"/>
			<xsd:attribute name="Width" type="xsd:double" use="optional"/>
			<xsd:anyAttribute namespace="##other" processContents="lax"/>
	</xsd:element>

Note that there is an existing element by this name which is a child element of Activity and should be deprecated.

The hRef provides a path to the JPEG file for the icon image. Of course this approach does not make the icon definition portable. We need a proposal to solve this problem. Also, do we want JPEG or something else?
