Call for Participation and Contributions:

You are invited to participate in an Open Forum about the capabilities, uses, content, development and operation of registries. This is the sixth in a series of international conferences on metadata registries. The Open Forum will describe and demonstrate how to use the following:


·       ISO/IEC 11179 Metadata Registries

·       Universal Discovery, Description and Integration (UDDI)

·       OASIS/ebXML Registries

·       SQL Catalogs

·       CASE Tool Repositories

·       Software Component Registries

·       Ontological/Terminological Registries

·       Dublin Core Registries

A major theme will be cooperation between the various registries.  

See the following for a description of the concept for this Open Forum:
Concept Presentation in PowerPoint, Concept Presentation in PDF

The Open Forum will bring together persons implementing, intending to implement, or otherwise interested in these registries to:

· provide a forum for information exchange,

· describe the registries and how to implement and use them

· encourage collaboration in the development and exchange of content between registries,

· encourage collaboration in the development of registry implementations,

· encourage standards development efforts to work together, and

· participate in "tracks" that discuss the relevant standards and the use of registries in the fields of  defense, environment, healthcare, learning technologies & knowledge management, statistics (e.g., census and labor/economic statistics), transportation & aviation, and electronic commerce. Special attention will be given to XML aspects of these registries. 

The various types of registries may be established and operated by individual organizations (such as corporations or government agencies), or by larger aggregations such as trade associations and standards organizations.

You are invited to participate by attending any of the presentations or by contributing articles/presentations/position papers to be viewed on the Open Forum Website.



Open Forum Goals:

The central goal of this Open Forum is to share knowledge and experience about standards and implementation experiences. The Open Forum sessions will examine emerging technologies and describe what people are doing and planning in their implementation efforts. This will disseminate experiences among those who have implementations, those who are beginning to implement, and those who are considering the use of registries.

A related goal is to develop collaborative efforts to share metadata between registries. It is highly desirable to share the cost and effort of developing and maintaining standard metadata.



Issues for the Open Forum:

The following is a list of topics that we expect to address:

· Tutorials on registry fundamentals. What are the key concepts found in selected standards? Tutorial descriptions will cover relevant standards including the six parts of ISO/IEC 11179, XML Registries, UDDI. SQL Catalogs, Business Component Registries, Ontological Registries, etc.

· Implementations and demonstrations. Experiences that participants share to assist us to develop and operate registries. We will describe business cases, design issues, content population and operations.

· Tutorials on capabilities of registries. What are the essential concepts in related areas such as terminology, XML-Schema, and business objects?

· Subject area tracks. What organizations are doing with registries in the areas of health care, environmental protection, statistics (e.g., census and labor/economic statistics), transportation & aviation, defense, learning technologies & knowledge management, and electronic commerce. How can interested organizations participate in these efforts or start their own?


· Cooperation between registries. How we can develop interoperable or cooperating registries, so that users can manage data semantics.

· Discussion of Semantics. Metadata can facilitate access, use, understanding, and sharing of data across time and space by systematically describing the content, structure, and semantics of data residing in information systems, data warehouses, databases, files, documents, messages, etc. Registries are facilities with associated procedures for storing and registering detailed metadata from multiple sources and diverse organizations in a common structured form. This will include fundamental notions about data elements, data semantics, models of metadata attributes, naming and identification issues, classification schemes, value domains, data registration essentials, Registration Authority essentials, etc.

· Terminology. How do we specify and manage thousands of concepts and the associated linguistic expressions that denote semantic content?

· Semantic structures. How do we organize concepts and terms into structured sets that can be deployed in useful technologies? Concepts and terms can be organized into thesauri and topic trees that are deployed via search engines. Concepts/terms can be organized into data element concepts, data definitions and value domains which are deployed as data elements in data base management systems and electronic commerce messages. Other structured sets of concepts/terms include controlled vocabularies, taxonomies, and ontologies that may be deployed in technology ranging from web enabled forms to intelligent information services comprised of query agents, request brokers, resource agents and other Internet middleware.

· Context. How do we accommodate the diversity of languages, naming schemes, name spaces, and discipline-specific terminology that demand alternate forms of  terms to be used for definitions, names, value domain representations, etc.?

· IT enabled data standards. How can a metadata registry be used to improve the design of data? What is necessary to IT enable data standards--that are originally written on paper--by international, national, government and private sources? The content of many standards needs to be restructured in order to record them in metadata registries and to deploy them in information systems.

· Interchange. How can metadata registries facilitate all types of electronic data communication including: EDI, web enabled forms, XML data transfers, etc.

· Understanding. How can registries help make specialized knowledge available to others who want to use the data? If someone from a different organization wants to use data several years after its creation, what metadata will he/she need to make meaningful use of it?

· Discovery. Discussion of the structure and kinds of metadata necessary to help humans and software find data and business services that they need.
