“Integrating Standards in Practice”

10th Open Forum on Metadata Registries

July 9-11, 2007New York City, NY USA

“Integrating Standards in Practice”

Solution: Technical Reference Dictionaries / Ontologies

● Develop industry wide (national/international standardized) technical reference dictionaries / product ontologies

● Define Workflow for online maintenance and standardization (ISO Standards as database group)

● Define interfaces (technical, legal, workflow,..) between various reference dictionaries

● Support software vendors accessing reference dictionaries

Product characterization standards – status quo

● Many different information models for product characterization and classification – ISO TC184/SC4: ISO 13584/IEC 61360, ISO

22745, ISO 15926,, …)– ISO/IEC JTC1: ISO/IEC 11179, …– RDF, OWL– …

● Many different product classification standards (eCl@ss, UN/SPSC, NATO (NCS), company-spec., ...)

● Many different product data exchange standards (XML dialects, XML-frameworks, MS-EXCEL, CSV, company-spec., ...)

“Integrating Standards in Practice”

Problems stalling industrial usage

● NO interoperable models for product characterization ontology (classes, properties, classification, terminology, graphical symbols, …)

● NO harmonized industry spanning standardization processes for product characterization ontology development and maintenance

● NO aligned processes to exchange or access product characterization ontology

Industry needs product characterization to capture

product knowledge

“Integrating Standards in Practice”

Consequences

● High efforts to create and maintain product characterization terminology

● Errors occurring using redundant or different product ccharacterization semantics

● Increased communication- and coordination-efforts

● Reduced benefit on usage

There is no e-Business without reliable e-Semantics

ISO 29002 Exchange of product and service characteristic data

● Project Managers:– Dr. Gerald Radack, CTC– Nikolaus Ondracek, Paradine

● ISO 29002 Part 20 – Concept dictionary resolution service (CDRS)– Host: ISO TC184/SC4/WG12– Service definition to resolve reference dictionaries (for

the beginning TC184/SC4 standards ISO 22745, ISO 13584)

– Goal: Harmonize resolution of product knowledge to its terminology and if applicable to its formal semantics independent of underlying ontology representation data model

“Integrating Standards in Practice”

ISO 29002-20: Design Principles (1)

● Architecture– Open for all reference dictionary/ontology standards

– Different Layers for Resolving Requests• allow organizations to provide reference dictionaries tailored to their need • disconnect formal concept ontology providers from terminology providers

– Stateless Protocol

– Abstract Interface Definition (IDL) and WSDL provided

● Distributed Architecture– Allow easy access for providers

– Ensure availability of service

– Ensure performance for queries

– Allow distributed maintenance

“Integrating Standards in Practice”

ISO 29002-20: Design Principles (2)

● Localisation– multi-lingual

● Support of different representation standards– define generic protocols allowing to perform information retrieval

from any kind of product characterization ontologies, whatever be their underlying representation model (e.g., ISO13584, ISO TS 22745-10, OWL,..…).

● Allow different business models– No constraints on business models for operation of the service – Independent from maintenance model

“Integrating Standards in Practice”

Standardized product characterization is reducing the

complexity of all business processes throughout the

supply chain

Conclusion

● Industry heavily needs standardization of product characterization terminology and ontology

● Many industry spanning activities using various representation standards are in progress

● ISO 29002-20 is leveraging use of product ontologies by supporting online access independent of ontology representation models
