PLM XML/TC XML Export Import Administration : Basic Understanding

[Statements are taken from PLM XML/ TC XML Export Import Administration PDF]

PLMXML for a standard PLM XML import or export i.e Between Teamcneter Unified sites and non Teamcenter sites

TC XML if you are using Data Exchange to move data between Teamcenter and Teamcenter Enterprise sites.

Transfer mode objects are created in PLM XML/TC XML Export Import Administration and are displayed as options when users import or export objects or system data using one of the Teamcenter applications. 
They allow users to export and import data with little knowledge other than the name of the transfer mode object that they should use; for example, ToCompanyA, FromCompanyB,

or ToCompanyB.

Transfer mode objects are made up of the following items that configure the import or export operation.

• Closure rules

Define the scope of the data translation.

• Filter rules

Use conditions to apply a finer level of control over which data gets translated

along with the primary objects.

• Action rules

Sets of methods that can be called before, during, and after the translation.

• Property sets

Provide a mechanism for PLM XML objects to have arbitrary properties in the form of UserData elements.

Managing closure rules

Closure rules control the scope of the data translation on both input and output.

They specify how the data structure is traversed by specifying which relationships are of interest and what should be done when these relationships are encountered.

Closure rules are comprised of five parts: primary object selector, secondary object selector, relation selector, action, and an optional conditional clause. Closure rules generally come in sets. The closure rule clauses are evaluated in order for each target object. The first applicable rule determines the disposition of the related object.

A rule is applicable only if the target object fits the primary selector, the secondary object fits the secondary selector, the relationship between the two objects fits the relationship selector, and the conditional clause evaluates to TRUE. The action

of the applicable closure rule clause determines how the translator handles the secondary object.

If no rule applies, the object is skipped. If the action is TRAVERSE, the object becomes another target of the translation. If the action is PROCESS, the secondary object is written (into either PLM XML or the Teamcenter database), but no closure rule clauses are applied to the secondary object’s related objects. If the action is

SKIP, nothing is done with the object.
