Currently - DAnCE only supports the deployment & configuration of CORBA - Component Model (CCM)-based applications, though we are interested in - generalizing it for other component models in future work. DAnCE uses - XML descriptors to drive the deployment it performs. One way to - generate these descriptors is using the <b>Co</b>mponent - <b>S</b>ynthesis using <b>M</b>odel-<b>I</b>ntegrated <b>C</b>omputing - (<a href="http://www.dre.vanderbilt.edu/cosmic">CoSMIC</a>) tool-suite. - DAnCE currently uses <b>C</b>omponent <b>I</b>ntegrated <b>A</b>CE - <b>O</b>RB (<a href="http://www.dre.vanderbilt.edu/CIAO">CIAO</a>) as - the underlying CCM implementation in the current release, though again - we are interested in generalizing it for other CCM implementations in - future work. - </p> - - <h3>D&C XML Schema Handling</h3> - - <p> The XML handlers shipped with DAnCE are capable of handling almost - all elements that are defined in the D&C schema. In this context, - handling refers to reading the XML tags and converting them to the - equivalent in-memory IDL-based data structures defined by the - specifications. DAnCE supports the following types of descriptors - specified in the D&C specification:</p> - <ul> - <li> - <p> - <b>CORBA Component Descriptor(.ccd)</b> – - Contains information about component interfaces including - component ports. - </p> - </li> - <li> - <p> - <b>Component Implementation Descriptor(.cid)</b> - – Contains information about component implementations - which might be either monolithic or assembly based. In the case - of assembly based implementations, this descriptor also captures - the dependencies and the connections among components - </p> - </li> - <li> - <p> - <b>Implementation Artifact Descriptor(.iad)</b> - – Contains information about implementation artifacts - in-cluding dependencies between such artifacts - </p> - </li> - <li> - <p> - <b>Component Package Descriptor(.cpd)</b> – - Contains information about grouping of multiple imple-mentations - of the same component interface into component packages - </p> - </li> - <li> - <p> - <b>Package Configuration Descriptor(.pcd)</b> - – Contains information about specific configurations of - such component packages - </p> - </li> - <li> - <p> - <b>Component Domain Descriptor(.cdd)</b> – - Contains information about the target environment in which the - component-based application will be deployed - </p> - </li> - <li> - <p> - <b>TopLevel Package Descriptor(.tpd)</b> – Contains - information identifying the top-level element in a component - package descriptor which might include information about multiple - elements - </p> - </li> - - <li> - <p> - <b>Component Deployment Plan(.cdp)</b> – Contains - information that actually drives the deployment including - information about individual components that represent the - leaf-nodes in case of a hierarchical assembly, connections - between components, and assignment of components to nodes etc. - </p> - </li> - </ul> - <p> For all the above elements, DAnCE supports proxying of the elements - as defined by XMI, i.e, DAnCE supports both parsing of the elements - inline and reference through <b><code>href</code></b> attribute. Some - D&C schema elements are however not handled, including:</p> - <ul> - <li> - <p> - <b>Deployment:Any</b> – This is a complex - element that is composed of many sub-elements. Currently, DAnCE - only parses a subset of the sub-elements of - <b><code>Deployment:Any</code></b>. Specifically, DAnCE supports all the - basic data types defined as part of <b><code>Deployment:Any</code></b>, - and doesn't understand any complex types. - </p> - </li> - <li> - <p> - <b>xmi:Extension</b> – This element allows the - augmention of the standard D&C schema with user-defined - elements. Currently DAnCE doesn't support user-defined extensions - to the schema. - </p> - </li> - <li> - <p> - <b>Deployment:Requirement</b> – This element is - allows the description of requirements of component-based - applications. Since handling this description requires interaction - with the <b><code>TargetManager</code></b> interface (which is not yet - supported), support for <b><code>Deployment:Requirement</code></b> is not - present. - </p> - </li> - <li> - <p> - <b>Deployment:ComponentPropertyDescriptioncode></b> – - This element is used to specify default values for attributes of - component. DAnCE doesn't support setting the values for attributes - of components using this tag. - </p> - </li> - <li> - <p> - <b>Deployment:ComponentExternalPortEndpoint, - Deployment:ExternalReferenceEndpoint</b> – These - elements are used to specify connections between ports of - components in one assembly with ports of components in a different - assembly, or connections between component ports and external - connection endpoints. These features are needed to support - assemblies of components. DAnCE doesn't support yet hierarchical - assemblies, i.e., creation of assemblies which can themselves - contain sub-assemblies. - </p> - </li> - <li> - <p> - <b>Deployment:PlanPropertyMapping</b> – This - element is used to delegate property mapping between a component's - external properties to properties of subcomponents that actually - implement the behavior of the larger component. Since DAnCE doesn't - support hierarchical assemblies, this tag is not yet supported. - </p> - </li> - </ul> - <p> We plan to support these features in future versions of DAnCE. - </p> - <hr /> - <h3> D&C Management Interfaces</h3> - - <p> The D&C specification defines a set of standard CORBA - interfaces that are used to perform the deployment of component-based - applications. These interfaces depend on the in-memory IDL data - structures that are built by DAnCE's XML handlers. Below we outline the - list of interfaces defined by the specification and the level of - support for each interface in DAnCE:</p> - <ul> - <li> - <p> - <b>RepositoryManager</b> – Only the - <b><code>installPackage()</code></b> and <b><code>findPackageByName()</code></b> - operations of this interface are implemented. - </p> - </li> - <li> - <p> - <b>TargetManager</b> – This interface has not - been implemented at all. Implementation of this interface is - planned for the future. - </p> - </li> - <li> - <p> - <b>ExecutionManager</b> – All operations defined - in this interface are implemented. - </p> - </li> - <li> - <p> - <b>DomainApplicationManager, DomainApplication</b> - – All operations except <b><code>getApplications()</code></b> - operation of DomainApplicationManager are implemented. - </p> - </li> - <li> - <p> - <b>NodeManager </b>– All operations except <strong><code>joinDomain()</code></strong> and <strong><code>leaveDomain()</code></strong> operations of NodeManager are implemented. </p> - </li> - <li> - <p><b> NodeApplicationManager, NodeApplication</b> – All operations defined in these interfaces are - implemented. </p> - </li> - </ul> - <p> - We plan to finish implementing the unsupported features in future versions of DAnCE. - </p> - <p> - <a href="http://validator.w3.org/check?uri=referer"> - <img src="http://www.w3.org/Icons/valid-xhtml10" alt="Valid XHTML 1.0!" - height="31" width="88" /> - </a> - </p> - <address> - Last modified $Date$ by $Author$ - </address> - </body> -</html> |
