About Application Resources Management (ARM)

The Application Resources Management (ARM) System is a runtime component used by applications to ask for physical resources. This system is based on a catalog, called ARM catalog that references physical resources.

• ARM Catalog
• Search Method

ARM Catalog

The catalog is a standard CATIA catalog created in the Catalog Editor. It must be based on a fixed structure containing the following keywords:

• Name: Corresponds to the name of the resource i.e. the one created by default by the catalog application (for selected features, this keyword cannot be filled freely).
• Logical Name: Corresponds to the logical name of the resource. It represents the resource identifier. The value must be unique since it will be used by ARM to find the corresponding resource in the catalog.
• Type: Corresponds to the type of resource that you are trying to reach. Its value must be one of the following values:

  AssemblyTemplate	Analysis
  PowerCopy	Drawing
  UserFeature	Product
  RuleBase	PartTemplate
  Rule
  Part

• Usage: Corresponds to a comment indicating what this resource is used for.

ARM catalogs are to be stored in the CATIA runtime view (in the KnowledgeResourceCatalogs directory) in order to be taken into account by the Application Resources Management system. ARM uses the concatenation of CATKnowledgePath and CATKnowledgeBuildPath to store (buildtime view) and retrieve (runtime view) the Knowledge resources.

Search Method

Queries performed on the catalog are based on the logical names, on the location, and also on the resource type. The system first finds an ARM catalog which has to be stored in the knowledgeResourcesCatalogs directory, then finds a row where the logical name is equal to the logical name given as an input, then reaches the physical resource attached to the catalog component. If a type of the resource is provided, it checks that the type of the physical resource found is correct and raises an error if it is not the case. If the resource is not found and is required, the system tries to find it under a KnowledgeResources directory (determined by the same concatenation as the KnowledgeResourcesCatalogs one).

Depending on the type of the resource, the system looks for a file with the following extension:
