SDD 1.1 Proposal

Current Situation

• SDD runtime “walks” resources in topology• Resources are cataloged and cross

referenced w/ profile(s)• If a resource in topology is encountered

that is not referenced in a profile, the runtime aborts

Scenario(s)/Use Case(s)

• SDD producer may want to type cast a resource for future management ops but use generic properties at deployment time– Example: A producer wants to deploy a

database system and there is a need post-deployment to identify that resource as a database system. However, at install time the only property needed is install location

Proposal

• Allow SDD producers to type cast resources– Add an optional attribute to ResourceType– Call the attribute implementedBy and have it

be an IDREF to another hosted resource in topology

Proposed SchemaIn sdd-common add the following

<xsd:complexType name="ResourceType">

<xsd:sequence>

<xsd:group ref="sdd-dd:DescriptionGroup" minOccurs="0"/>

<xsd:element name="Name" type="sdd-dd:ElementValueType" minOccurs="0" />

<xsd:element name="Property" type="sdd-dd:PropertyType" minOccurs="0" maxOccurs="unbounded"/>

<xsd:element name="HostedResource" type="sdd-dd:ResourceType" minOccurs="0" maxOccurs="unbounded"/>

<xsd:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>

</xsd:sequence>

<xsd:attribute name="id" type="xsd:ID" use="required"/>

<xsd:attribute name="type" type="sdd-dd:ResourceTypeNameType" use="required"/>

<xsd:attribute name="implementedBy" type="xsd:IDREF" use="optional"/>

<xsd:anyAttribute namespace="##other" processContents="lax"/>

</xsd:complexType>

Proposed Schema

Example<sdd-dd:Topology>

<sdd-dd:Resource id="os" type="sp:CIM_OperatingSystem">

<sdd-dd:HostedResource id="DatabaseServer" type="sp:CIM_DatabaseSystem">

<sdd-dd:HostedResource id="SimpleDatabase" type="sp:CIM_CommonDatabase" implementedBy="OSInstallofDBProduct" />

</sdd-dd:HostedResource>

<sdd-dd:HostedResource id="OSInstallofDBProduct" type="sp:CIM_InstalledProduct"/>

</sdd-dd:Resource>

</sdd-dd:Topology>

Actions if approved

• Minor schema change• Specification update to document the new

attribute
