This technical description of Capabilities describes the purpose of Capabilities and their
relationship to other PLCS components.
Capabilities provide guidance on how the IS0 1030-239 PLCS information model and associated
Templates should be used.
They correspond to the "chapters" of a notional PLCS usage guide within which a set of
Templates are documented, which are then reused by multiple DEXs as shown in Figure 1.
The concepts represented in the Capabilities are generic business level concepts
(such as a "part" or an "approval") whose meaning is agreed within the
PLCS OASIS community and is common to most applications of PLCS but which are not specific to a particular industrial
domain.
The Capability description is both graphical and textual to facilitate human understanding and
consists of a business overview and a detailed description of the usage of the information model
Reference Data classes.
Each
Capability also documents a set of one or more "Templates"
.
Each Template provides a precise, computer interpretable specification of which PLCS entities are required
and how they should be populated.
See the Templates section for further details on Templates.
Examples of Capabilities in PLCS are:
The structure of the Capability is as shown in Figure 2 and comprises:
In summary, Capabilities:
Most Capabilities belong to one of three basic types, with the type often reflected in Capability name. Namely:
Each Capability is identified within the DEXlib repository by a number, an identifier and a name, e.g.
These are assigned to the Capability in the initial development process.
Each Capability contains:
