-- the repository of information about
OASIS PLCS Data EXchange Specifications (DEXs)
and other related technology developed by the
OASIS PLCS Technical Committee.
specify the information to be exchanged and shared in order to support the life cycles of complex assets.
The DEXs identify coherent subsets of ISO 10303-239 Product Life Cycle Support
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 in the
OASIS PLCS TC Publications are derived from the content that is developed (by the TC) on DEXlib.
However, it is the publication that is the subject of standardisation, not DEXlib, which is a development environment
for the OASIS PLCS TC.
The DEXlib repository of DEXs and their supporting components is organized as follows:
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;
Capabilities: An index of all the Capabilities;
Capabilities provide guidance on how the
information model and templates should be used.
Business DEXs: An index of all the Business DEXs.
These are DEXs developed for a specific business domain. They are not standardized through OASIS
but are presented here for information and as examples of PLCS usage.
They are grouped
into Business contexts that define the
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
Schemas: An index of the AP239 schema and the DEX schemas, both as
EXPRESS models and XML Schemas.
For a summary of these components and inter relationships, see
"DEX technology overview".
In addition to the components listed above, DEXlib also includes the PLCS Help and
Information 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.
The PLCS DEX Help and Information Pages are divided up into the following sections:
