1. “Integrating Standards in Practice”
10th Open Forum on Metadata Registries
July 9-11, 2007
New York City, NY USA
Concept dictionary resolution service ISO (CDRS)
Nikolaus Ondracek, Paradine
An international conference to share and advance knowledge and experience about standards;
the technologies that build upon them, and implementation experiences. 

2. Mass with SI-unit: 1kg: 1 kg IS NOT equal 1 kg ? calculated scaled
estimated
compared
1 kg IS NOT equal 1 kg ?

3. Product – Specification Sheet
Easy to understand
(for German speakers)

4. Compare products – e.g. bearings
Supplier 2
Ready for
E-Business ?
Supplier 3
Supplier 1
d corresponds to: FW of supplier d1 of supplier A1 of supplier 3
roller bearing

5. 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

6. Projects following ISO/IEC Guide 77
IEC (IS)– electrical/electronically properties
ISO (IS)– measurement instruments
ISO (IS)– mechanical fasteners
ISO (DIS) – precision tools
ISO (DIS)– optic und photonic
IEC (CD) – industrial measurement instruments
ISO TC 4 (WD) – bearings
ISO TC 59 - (PWI) - HVC devices
...

7. Other relevant ISO projects
ISO Electronic business eXtensible Markup Language (ebXML)
ISO – Integration of lifecycle data for process plants including oil and gas production facilities
ISO – Open Technical Dictionary
ISO/IEC – Information technology — Metadata registries (MDR)
ISO 8000 – Industrial Data quality (ISO TC184/SC4) ….

8. 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 UN/SPSC, NATO (NCS), company-spec., ...)
Many different product data exchange standards (XML dialects, XML-frameworks, MS-EXCEL, CSV, company-spec., ...)

9. 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

10. There is no e-Business without reliable e-Semantics
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

11. ISO 29002 Exchange of product and service characteristic data
Project Managers:
Dr. Gerald Radack, CTC

ISO 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

13. 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

14. 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 , OWL,..…).
Allow different business models
No constraints on business models for operation of the service
Independent from maintenance model

15. ISO 29002: Concept Identifier based on ISO 11179-5

22. Conclusion
Industry heavily needs standardization of product characterization terminology and ontology
Many industry spanning activities using various representation standards are in progress
ISO is leveraging use of product ontologies by supporting online access independent of ontology representation models
Standardized product characterization is reducing the complexity of all business processes throughout the supply chain
