What is PLib? I - A model for dictionnary / product ontology: Characterization of an object = 1 class + a set of property values Multilingual : Class and properties = 1 language independent identifier + a set of translatable attributes II - A Model for librairies / catalogues: Objects are: - gathered into classes, - described by properties values, and possibly - associated with representations (e. g. , geometry) III - Domain ontologies For each particular technical domain (e. g. , electronic components, fasteners, . . . ), PLib ontologies need to be defined. 3

Advantages of the PLib model • Defining multilingual Product semantics: 1 - Parts are structured as a specialization hierarchy: washer / lock washer internal teeths • Catalogues may be queried at various levels of details 2 - Properties may be shared across ontologies • decentralized view of ontology development with parallel work and shared responsabilities • Defining corporate component database 3 - Each company may choose its own hierarchy, select standard properties, and add its own properties • • Independence of database with automatic information exchange and integration Electronic commerce 4 - Standard ontologies provide multilingual product semantics • automatic processing of electronic commerce and B 2 B transactions 5 - The library model contains all catalogue information • automatic generation of active and multilingual electronic catalogues 4

PLib Status? • All the standard documents are now International standards – Model of ontology jointly published ISO and IEC from 1998 to 2004 – A total of 12 international standards • Product ontologies developped as International standards – – – – electronic components process instruments Fasteners measuring instruments machining tools bearings mechanics optics and photonics IEC 61360 -4 ISO 13584 -511 ISO 13584 -501 ISO 13399 ISO 23768 ISO/TC 10 NWI ISO/TC 172 NWI 5

New developments • ISO / IEC – A guide is under ballot for using PLib in all ISO and IEC TC • ISO TC 184/SC 4/WG 2 – XML schemas for PLIB exchange (Onto. ML) have been distributed for review – An improved version of the ontology model has been balloted • Cooperation is initiated with UN/CEFACT for eb. XML EDI (CEN/ISSS c. CAT) • An international consortium has been set up : OIDDI: Open and Interoperable Domain Dictionary Initiative • to promote the emergence of compatible and complementary ontologies • to ensure orthogonality between dictionaries and business processes – Participants: Rosetta. Net, ECALS/JEITA, UNSPSC, e. Cl@ss, IEC SC 3 D, ISO PLIB • Status: Pending a proposal for a CEN/ISSS Workshop has been submitted • National Standards: Japan, France, Germany. . . 6

Software Tool Mediator • Mapping of catalogue data of companies to – Standard dictionaries – Dictionaries of other companies / marketplaces Mediator PDM EXCEL BMEcat e. Class ETIM SAP Profi. Class 16

Basic functionality of the Mediator Supplier Customer Dictionary mapping Supplier Cat. Customer Catalogue Transformation 17

Class mappings • Class mappings specify in which class of the target dictionary products will be put • 1: 1 • N: 1 1: N mappings 18

Property Mappings • Property mappings determine the value which is given to a property in generated e-catalogue • 1: 1 and 1: n mappings – The value of the target property is taken from the related source property – One source property may be mapped to several target properties • Transformation functions – Predefined functions – User defined functions (Syntax taken from SQL) 19

Prescriptions • Codification – Need : To have a unique international interoperable standardised code. Will replace corporate reference in all exchanges – Decided solution : All suppliers must provide a ISO/IEC 15459 -3 code (e. g. , EAN, ODETTE, EDIFICE, …) codifications are compliant (Currently only 45% of the 100 first manufacturers) • Characterization – Need : To have an homogeneous description of all items in the same class. – Decided solution : All supplier must provide data and catalogues in files conforming with ISO 13584 PLib, and according to the NPM shared ontology • Classification – Need : To group similar products in the same group – Decided solution : All supplier must reference an existing recognised international classification: e. Cl@ss 29

Estimated savings • For PSA and RENAULT : – Information capture and updating of data : • suppression of internal keying-in in each Group – reliability, richness, transparency, consistent information : • reduction of the number of administrative claims, e. g. procurement, accountancy, warehouse, … • reduction of the maintenance costs or of production loss, e. g. stops, breakdowns, … Globally : over 3 Million Euros of yearly savings each Group – 35% from information capture/update, – 20% from claims, – 45%st from production losses • For all other actors : no figures, but : – Reduction of claims – Cost of transcodification/translation of catalogues (formats and contents) 30

Three level structure of the project • The NPM consortium activity (Michelin, Alcan, Galia, Saint Gobain, Schneider, Air liquide…) • Continue development of a shared NPM ontology • Develop a French standard on the previous prescriptions • PSA and Renault’s common project • Adoption of the 3 concepts • replace each Company’s tools (as old as 25 years) and migrate to a PLIB -based storage structure • The LMPR Renault pre-project prescribed parts LMPR = List of Renault – Size of the project: – 4000 articles, 145 manufacturers, 211 classes – Documention package linked to each family, sometimes to each article – Time schedule of the project – PLIBEditor deployed in the 145 manufacturers June 2005 31

Conclusion: Vision for the next 5 years • Over the next 5 years, all global players will have changed – their current item databases (with same attributes for all products) – for PLib-like databases (Structured classes with specific properties). • Over the next 5 years, all global players will have changed their requirements about product information: – product = product + characterization data – full electronic exchange not only for e-commerce (commercial data) but also for engineering (technical data) • integration of engineering and procurement • PLIB is just in time: – – the technology is mature the technology is good New competitors emerge just to hurry up to promoting it and establishing it in Europa, in Asia …and elsewhere 33
