  1. PLib ontologies(ISO 13584 / IEC 61360):Where are we ? Guy Pierra pierra@ensma.fr

  2. Content • Standardization • Tools availability • Who use PLIB? • Conclusion: Vision for the future

  3. 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.

  4. Advantages of the PLib model • Defining multilingual Product semantics: 1 - Parts are structured as a specialization hierarchy:washer / lock 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 B2B transactions 5 - The library model contains all catalogue information • automatic generation of active and multilingual electronic catalogues

  5. 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 IEC 61360-4 • process instruments IEC 61360-4 • Fasteners ISO 13584-511 • measuring instruments ISO 13584-501 • machining tools ISO 13399 • bearings ISO 23768 • mechanics ISO/TC 10 NWI • optics and photonics ISO/TC 172 NWI

  6. New developments • ISO / IEC • A guide is under ballot for using PLib in all ISO and IEC TC • ISO TC184/SC4/WG2 • XML schemas for PLIB exchange (OntoML) have been distributed for review • An improved version of the ontology model has been balloted • Cooperation is initiated with UN/CEFACT for ebXML EDI (CEN/ISSS cCAT) • An international consortium has been set up : OIDDI: Open and Interoperable Domain Dictionary Initiative • to promote the emergence of compatibleandcomplementaryontologies • to ensureorthogonalitybetween dictionariesandbusiness processes • Participants:RosettaNet,ECALS/JEITA, UNSPSC, eCl@ss, IEC SC3D, ISO PLIB • Status: Pendinga proposal for a CEN/ISSS Workshop has been submitted • National Standards: Japan, France, Germany...

  7. Content • Standardization • Tools availability • free suite for standard ontology development (LISI/ENSMA, Fr) • Mediator system for ontology mapping (Semaino, De) • Online dictionary / catalogue server(Paradine, At) • Large size component DBMS (Toshiba Corp., Jap) • free browser/publisher (CNIS, CN), eCommerce server (Komerko,Fr)... • Who use PLIB? • Vision for the future

  12. OntoDB 2/2 Ontology management Extraction tools PLIB Editor-like front end

  13. Query language for PLIB and OBDB OntoQL • A language for creating / updating / querying ontology and ontology based data SELECT #name[en] FROM #CLASS SELECT #code, # version, #preferred_name, … FROM #CLASS WHERE #name[en]=‘Beach Paddles’ SELECT Reference, Configuration, Weight, Color, Length FROM "Beach Paddles" WHERE Color = ‘vert’ or Reference like ‘%3’ or Color = ‘jaune’

  14. OntoWeb 1/2 • Generic Web interface for accessing ontology-based databases • Global architecture: HTTP Server (Apache) Controller(Servlets) View(JSPs) HTTP Request HTTP Response Application Layer(Java Beans, Action classes) Application Server (Tomcat) Query Layer(OntoQL) Business Objects - OntoAPI(Java API) DBMS Server (PostGRES) DBMS Server (SQL Server) Mapping Layer(Hibernate) OntoDB FlatLIB

  16. Mediator BMEcat PDM eClass EXCEL ETIM SAP ProfiClass Software Tool Mediator • Mapping of catalogue data of companies to • Standard dictionaries • Dictionaries of other companies / marketplaces

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

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

  19. 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)

  29. 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: eCl@ss

  30. 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)

  31. 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-projectLMPR = List of Renault prescribed parts • 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 • Integrated catalogue circulated to integrator by December 2005

  33. 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
