PLCSlib Overview

PLCSlib -- the repository of information about Product Life Cycle Support (PLCS) PLCS, the OASIS PLCS Data EXchange Specifications (DEXs) and other related technology developed by the OASIS PLCS Technical Committee.

The DEXs specify the information to be exchanged and shared in order to support the life cycles of complex assets. The DEXs identify coherent subsets of the PLCS Platform Specific Model (PLCS PSM) that support data flows needed for specific business processes.

The OASIS PLCS Technical Committee is responsible for defining, developing, testing, and publishing of OASIS PLCS DEXs, and for liaison with ISO TC 184/SC4. More information about the OASIS PLCS TC can be found at (http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=plcs).

OASIS PLCS TC Publications are derived from the content that is developed (by the TC) on PLCSlib. However, it is the publication that is the subject of standardisation, not PLCSlib, which is a development environment for the OASIS PLCS TC.

The PLCSlib repository of DEXs and their supporting components is organized as follows:

Contexts: An index of all the Contexts;
A Context identifies a domain or business purpose area for which DEXs are defined;
DEXs: An index of all the DEXs;
A DEX identifies and documents a subset of the ISO 10303-239 (PLCS) information model required for a specific business purpose;
Templates: An index of all the Templates;
The usage of the PLCS information model by a DEX is defined through templates. The templates provide a precise specification of how the model is used to represent a given concept;
Model Usage Guides: An index of all the Model Usage Guides;
Model Usage Guides provide guidance on how the information model and templates should be used.
Reference data: An index of the Reference Data used by the DEXs;
Reference data provides a tailorable vocabulary that adds business specific semantics to the information model.
Concept model: A high level model of the main concepts used in ISO 10303-239. It is intended to be used to introduce on a single page the scope that PLCS addresses.
Activity model: The ISO 10303-239 Activity Model that illustrates the business activities that are supported by ISO 10303-239;
PLCS PSM: The PLCS Platform Specific Model (PLCS PSM) that is used as the data exchange form for all DEXs. The PLCS PSM is a SysML model;

In addition to the components listed above, PLCSlib also includes the PLCS Help pages that are provided to explain:

the business benefits and the technical composition of PLCS and the OASIS PLCS DEXs;
how a DEX is developed; and
how implementation of DEX based software is achieved.
