Boeing and Eurostep release joint report - A new approach to PLCS Web Services
Boeing and Eurostep have investigated a new approach to developing standardized PLCS Web Services.
The basic concept is that PLCS DEXs should be developed using mainstream technology. Resulting in cheaper, simpler and faster development and automatic generation of DEX based PLCS Web Services. The reduced complexity will allow more people to contribute to the success of PLCS.

The purpose of the OASIS Product Life Cycle Support (PLCS) TC is to establish structured data exchange and sharing to support complex engineered assets throughout their total life cycle.

These Data Exchange Specifications (DEX's) are based upon ISO 10303 (STEP) Application Protocol 239 (Product Life Cycle Support). The OASIS PLCS TC is responsible for defining, developing, testing and publishing of OASIS PLCS DEX's, and for liaison with ISO TC 184/SC4.

The Aerospace Industries Association (AIA) recommends adopting PLCS. "Engineering Data Interoperability - A Standards Based Approach" was published with the recommendation on 7 March 2008.

"Re-engineering the Aftermarket with PLCS" - new white paper on business benefits In co-operation with John Stark, the leading independent management and technology consultant in PLM, Eurostep has written a white paper on the business benefits of implementing PLCS. Recent changes in the business environment have opened new opportunities in the aftermarket. Successfully exploiting these trends presents many challenges, including both new commercial relationships and management of huge volumes of product data. The new approaches to meeting the challenges that are discussed in this paper will enable OEMs to provide effective low-cost global support for long-life complex engineered products such as airplanes, power plant, heavy vehicles, industrial machinery and equipment, elevators, trains, and weapon systems; as well as less complex systems. A coherent information environment in which the necessary data are available to all participating actors is a prerequisite for efficient product support. PLCS can be thought of as a new “world map” for product support. Like any new map, PLCS contains much that is familiar – a maintenance task is still a maintenance task – and many new discoveries. Just like a map, PLCS can be used in different ways. One is to solve business problems by automating data exchange between existing systems. PLCS can also be used to support a major update of processes across an entire organization. This white paper written by John Stark in co-operation with Eurostep describes the standard itself and explains how an organization can implement PLCS to achieve tangible business benefits. Examples are provided of PLCS projects in some well known organizations.

NIST Releases Lifecycle Management Standards Report The National Institute for Standards (NIST) has just released a study NISTIR 7339, "Analysis of Standards for Lifecycle Management of Systems for US Army --- a preliminary investigation". The study highlights the importance of ISO 10303, the Standard for Exchange of Product Model Data (STEP). The PLCS TC is working closely with ISO 10303 to develop Data Exchange Specifications. Download the NISTIR 7339 report.

Note for Developers of ISO 10303-239 (PLCS) Data Exchange Specifications The OASIS Product Life Cycle Support Technical Committee develops Data Exchange Specifications [DEXs], and their supporting infrastructure using the International Standard ISO 10303-239:2005(E) Industrial automation systems and integration — Product data representation and exchange Part 239: Application protocol: Product life cycle support.

The OASIS PLCS Technical Committee will consider any Data Exchange Specifications, Capabilities, and Reference Data developed by outside projects for adoption by OASIS. All material submitted should comply with the OASIS TC established process. Material will be reviewed by the OASIS PLCS TC Technical Oversight Group (TOG) prior to submission for acceptance by the PLCS TC members. If material successfully passes the OASIS TC ballot, it will be submitted to the OASIS membership for ballot and publishing as an OASIS standard.

To minimize the risk of non-compliance and consequent rework, projects or organizations developing Data Exchange Specifications based on ISO 10303-239 are advised to contact one or more of the following PLCS TC development experts:

Teams have been formed to complete the work offered to OASIS by the PLCS consortium, and DEX development is well underway. Significant progress is being made on the first eight DEX. However, there is still much to be done to finalise the Data Exchange Specifications based on the ISO PLCS standard, and additional resources would be welcomed by the DEX Teams, to support the development, documentation and testing of the final specifications.

PLCS uses an open source development environment based on XML and XSL scripts to facilitate the creation of compatible and interoperable specifications. There are opportunities for technical support with XSL expertise to support Infrastructure Maintenance.
