ISO/IEC JTC 1/SC 32 Data Management and Interchange
SC 32 PERIOD REVIEW
Excellent progress has been made in developing SQL, SQL MM,
RDA, Open-Edi, Metadata Registry standards, and we expect that progress to
continue in the future. Excellent progress
has been made in developing SQL. The remaining parts of the SQL:1999 standards
have been completed. An aggressive schedule for the next complete revision of
ISO/IEC 9075 has been set with a target end date of 1st quarter 2003.
The ISO/IEC 15944
standards have been approved to be freely available. This includes:
Information technology - Business Agreement Semantic Descriptive Techniques Part 1: Business Operational Aspects of Open-edi for Implementation
Information technology - Business Agreement Semantic Descriptive Techniques Part 2: Registration of Scenarios and their Components
And two additional parts.
JTC 1 has approved the ISO/IEC 11179 Metadata Registry family of standards to be freely available. These await ISO and IEC approval.
SC 32 MARKET REQUIREMENTS
Market requirements for SC 32 standards are driven by the rapid pace of hardware and software advancement as well as by the explosive growth of Internet/Intranet/Extranet applications. These drive a stream of market requirements that are addressed by SC 32 standards for data management and interchange, including metadata management. The data management market continues to grow rapidly in line with the geometric increase in the volume of data stored and served.
An SC 32 study period has found an increasing market demand for semantics management. This is needed for data in databases, EDI messages, text in documents (which may be stored in databases), etc. While there are several ISO standards for various terminology content and structure, there is little connection between those standards and their potential use for data management and interchange. SC 32 is exploring the market requirements for semantics management and the existing standards in order to articulate and then fill the unmet need.
Users are driving the market demand for metadata registries that describe the structure and meaning data. Major organizations are implementing metadata registries according to SC 32 standards and in the process are creating demand for extensions and broader coverage. This work is especially driven by the public access requirements of users and by market forces requiring the capability to share metadata between organizations.
The market demand for SQL database
products remains strong. The clear acceptance of the new SQL:1999 standards by
the database vendors is very encouraging. The development of new parts and new
features within the 9075 family of standards continues to be driven by
perceived market priorities; the effort applied and the scheduling of the
various parts has been adjusted accordingly.
Market demand of EDI and electronic commerce products grows as firms struggle to move into the electronic marketplace. Standards for EDI functions are necessary to facilitate this demand. The SC 32 work related to Open edi work and metadata registries is supporting JTC 1 involvement with the ISO IEC UN/ECE MoU Management Group.
Each part of SQL/MM standards is based on explicit requirements from a domain market. Especially, SQL/MM Part 2: Spatial specifying Spatial Data Management received much attention from TC 204, TC 211, and OGC (Open GIS Consortium) and is being developed under close coordination with TC 211 and OGC. Thus, we believe that our standards meet real market requirements.

SC 32 FOCUS NEXT WORK PERIOD
SC 32 has refined its program of work to ensure that it is focusing on those standards that will meet market requirements. SC 32 plans to continue to focus on developing standards for SQL, SQL/MM, Open edi and data semantics. SQL work is expected to be particularly active. The metadata registry market is becoming more active with implementations of ISO/IEC 11179.
Database Languages (WG
3) work is active with the focus on a completely revised set of ISO/IEC 9075
parts as well as two new parts addressing more Java support and XML
support. WG 3 has assumed some of the
projects from the former WG 5.
The Open-Edi (WG 1) is concentrating on on is the second part of ISO/IEC 15944: Information technology - Business Agreement Semantic Descriptive Techniques Part 2: Registration of Scenarios and their Components, and the fourth part of ISO/IEC 15944: Information technology - Business Agreement Semantic Descriptive Techniques Part 4: Business Transactions and Scenarios - Accounting and Economic Ontologyand ISO/IEC 18038 Identification, mapping and IT-enablement of existing standards for widely used encodable value domains. A key characteristic of commerce world-wide is that it makes extensive use of enumerated lists, code sets, etc. representing possible choices of common aspects in business transactions. The problem is that most of these code sets in use world-wide are paper-based and, even if available in electronic form, lack a computer-processable version. The objective of this standardization work is (1) the development of a tool to facilitate the creation of IT-enabled versions of existing sets of "codes representing X", and (2) to do so, in a manner which will support localization and multilingual requirements of the marketplace.
The Metadata Working Group (WG 2) is progressing the metadata registries with revisions to the ISO/IEC 11179 family of metadata registry standards. Part 3 of ISO/IEC 11179 was revised to incorporate a structure of a metadata registry and is now at ITTF for FDIS ballot. Technical reports on metadata registry content are progressing. The content TR addresses the exchange of metadata among ISO/IEC 11179-based registries that depends not only on standard-conforming software, but also on contents that are compatible across registries. The goal of this project is to produce Technical Reports that will promote a common understanding of the content of metadata registry data elements so that they can be shared among registries. The intent is to provide guidance by example in registering data elements. WG 2 intends to recommend using XML for accessing and interchanging information in 11179 conformant data registries. We expect that specific XML tags and data structures will be algorithmically derived from the normative UML data model specified in 11179 part 3. The Object Management Group (OMG) has already adopted a standard for XMI (XML Model Interchange), which we expect to recommend as one mechanism for such algorithmic derivation of XML representation from UML models. Work is also underway to foster interoperation between ISO/IEC 11179 metadata registries, XML registries, Universal Description, Discovery and Integration (UDDI) registries, database catalogs, ontology registries and CASE tool repositories. The SC 32 work is positioned to meet the deeper semantic management aspects of data management and interchange.
SC 32 OPPORTUNITIES
The Internet, electronic commerce, semantics management, object technologies, and XML represent major areas of opportunity where market forces are creating demand for SC 32 standards. We will continue to work with the others involved to identify the specific standardization needs and to respond with current and newly proposed standards.
XML represents a major area of opportunity where market forces are creating demand for standards and SC 32 is continually monitoring the work in this area and will react as soon as it sees and appropriate opportunity.
