Registries

Using this term loosely, there are several types of registries in the area of data management and interchange.

The registries have some related (overlapping?) content, which is extended and utilized in different ways.

The registries vary according to the intended purpose, granularity of contents, the level of semantics management.

Types of Registries

OASIS/ebXML XML Registries – XML Artifacts Register XML Artifacts - Includes schemas and DTDs. XML schema relate to a

paper form, EDI document, or reporting requirement. Emphasis on syntactic (structure) information.

ISO 11179 Metadata Registries – Data Semantics Register Data Elements, components of data elements and groups of data

elements. For example, country codes for customer place of residence. Includes: data element concepts, data elements (including representation), value domains, and (multiple) taxonomies.

Emphasis on semantic information such as definitions of data elements and value meanings, and stewardship responsibilities.

Universal Description, Discovery, and Integration (UDDI) Registries – Web-based Business Services A White page directory of the business activities of firms. Emphasis on interface specifications.

6October 2001

Types of Registries(continued)

Database System Registries (System Catalogs/Data Dictionaries/ Repositories) – Schema, integrity & operational info. Includes all elements of database schemas: data elements, relations, integrity

constraints. Emphasis on information required to make database systems work for queries,

etc., not on semantic management.

Case Tool Registries (Encyclopedias/Repositories) – Data model and application program logic Includes information needed to create a database and potentially the program

code for a system. Contains database schemas. Emphasis not on semantic management.

Ontological Registries – Concept Structures Includes relations among concepts (subsumption, inheritance,…) and axioms for

inference among concepts, e.g., temporal/spatial reasoning, etc. Emphasis is on semantics.

7October 2001

Types of Registries(continued)

Software Component Registries -- Software Components Reuse software components built on specific vender platforms

such as EJB, COM, CORBA IDL etc. Include basic common elementary objects and object patterns Emphasis on reusability of software component to build flexible

and standardized business systems.

How can we work toward interoperability? Standards developers Software developers Practitioners

27October 2001

XML Registry Efforts

OASIS Registry/Repository Specification OASIS and ebXML have merged into a single OASIS

Technical Committee chaired by NIST. OASIS specifications strength is in its classification

capabilities. Associations among objects make it easy to compare versions of similar objects.

OASIS allows organizations to register, classify, capture associations and dependencies, and record additional metadata for their objects of choice.

XML interface provides easy access. Members can exchange information with one another.

Major advantage is that the interface can remain stable for each interchange partner.

28October 2001

XML Registry Efforts (continued)

OASIS Registry/Repository Specification (continued) Registered objects associated with two pieces of information:

An electronic file consisting of a specific digital instance. The file containing the registered object is maintained by a repository.

Metadata for naming, describing, and locating the registered object and identifying its associations and relationships with other objects. The metadata is maintained by the registry.

Registry and repository are tied together in that the metadata includes a globally unique locator for a file.

Benefits of storing metadata in a registry include: reuse of data and metadata, efficient version control, unified understanding of registered objects, and promotion of consistency across organizational areas.

May be a driving force in commercial implementations that are interoperable between trading partners and meet government needs.

29October 2001

Speaking the Same Language

Company X publishes an XML Schema in a public repository.

Company Z retrieves XML Schema from repository and generates XML document from it.

Company Z sends XML document to Company X over shared communications link.

Company X verifies correctness of received XML document by checking it against well-known Schema.

Metadata Registry Efforts

ISO/IEC 11179 – Metadata Registries Background Specifies basic aspects of the kind and quality of metadata

necessary to describe data, and the management and administration of that metadata in a metadata registry.

Applies to the formulation of data representations, meanings, and relationships between them to be shared, independent of the organization that produces the data.

Focuses on semantics (the meaning of data) and management of semantic change.

Does not apply to the physical representation of data as bit and bytes; metadata refers to descriptions of other data.

31October 2001

Metadata Registry Efforts (continued)

Major aspects of ISO/IEC 11179 family of international standards apply to activities including:

The definition, specification and contents of data element dictionaries or data registries, including interchanging or referencing among various collections of data elements.

The design and specification of application-oriented data models, databases and message types for data interchange.

The actual use of data in communications and information processing systems. Interchanging or referencing among various collections of data elements.

Major implementations for ISO/IEC exist for environment, healthcare, intelligent transportation system, aviation, demographic and other programmatic areas.

The desire is to make these metadata registries interoperate with XML registries, with the 11179 registries handling deeper levels of semantic management.

Business Registry Efforts

UDDI effort defines a set of specifications making business accelerate use of B2B and commerce over the Internet easier.

This direct application-to-application integration is a core building block of the digital economy and will help reduce many of the configuration and compatibility problems.

UDDI is based on existing Internet standards and is platform and implementation neutral.

A formal standard is expected. Specification may have relevance to XML and metadata registries that could be registered in UDDI registries.

36October 2001

Database Catalog Efforts

SQL has the concept of a catalog Has info that database needs to operate

Not necessarily sharable

SQL has concept of Schema Metadata accessible by SQL

Relational systems may have a “dictionary”, but not specified by a standard

Area of possible coordination between SC 32 WGs

37October 2001

CASE Tool Repository Efforts

There are several proprietary encyclopedia/repository products.

Difficult to specify common model SC 7/WG 11 & CDIF (CASE Tool Interchange Format

committee) have established a common core of content and an interchange specification

OMG: UML metamodel describes UML Objects, the Meta Object Facility (MOF) provides a container & XMI provides for metadata transfer

OMG: UML Profile (set of stereotypes for particular domain

38October 2001

Software Component Registry Efforts

Commercial base software component registries are available in the market.

Flashline.com, ComponentAA, ComponentSquar.com Sometime, those components are called Business

Objects Software components are developed and reused among

specific vender platforms, such as EJB (Enterprise Java Beans), COM, CORBA with their own manner

No common framework is available so far, to share components among registries

39October 2001

Interoperability

Interoperability approaches Standards developers

Liaison between Standards committees. Software developers

Interoperability conformance testing. Practioners

Single points of data entry, interchange between software.

40October 2001

Four General Registry AreasA Work in Progress

Discovery mechanisms. Repositories of XML artifacts. Semantic registries–Business content mapping. Application Program Interfaces (APIs).

Work with NIST and others in the XML Working Group to prepare report covering registries including descriptions of:
