OGC Recommendation Available to the Public.Business/Technology Editors WAYLAND, Mass.--(BUSINESS WIRE)--Aug. 21, 2001 The Open GIS Consortium, Inc. (OGC OGC Office of Government Commerce (UK government) OGC Open Geospatial Consortium, Inc. OGC Office of the General Counsel OGC Open GIS Consortium, Inc. ) announces that an OpenGIS(c) Recommendation has been made available to the public. The paper titled "Recommended Definition Data for Coordinate Reference Systems and Coordinate Transformations" is available for public review at http://www.opengis.org/techno/specs.htm. This Recommendation Paper specifies a data model for metadata in support of the OpenGIS Coordinate Reference Systems (CRS CRS Course CRS Certified Residential Specialist (real estate certification) CRS Central Reservation System CRS Can't Remember Stuff (polite form) CRS Cost Reduction Strategy CRS Consumer Relations Specialist ) and Coordinate Transformations (CT) Implementation Specifications, and specifies standard definition data for the data model. Because the specified data model is more general than an OpenGIS Implementation Specification and more specific than the OpenGIS Abstract Specification, the work is being delivered in a Recommendation Paper. Representatives from three OGC member organizations, BAE SYSTEMS Mission Solutions, the Petrotechnical Open Software Corporation (POSC POSC Petrotechnical Open Software Corporation POSC Payroll Online Service Center (state of Maryland) POSC Personnel Occupational Specialty Code ), and Shell International Exploration and Production B.V. developed the model using object-oriented analysis and design Object-oriented analysis and design (OOAD) is a software engineering approach that models a system as a group of interacting objects. Each object represents some entity of interest in the system being modeled, and is characterised by its class, its state (data elements), and its thinking. This specification harmonizes and improves the relevant XML work previously done by OGC. This OGC standard data model for coordinate reference systems and coordinate transformation definition data is intended for initial use with OGC's OpenGIS Geography Markup Language The Geography Markup Language (GML) is the XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. (GML) and Coordinate Transformation (CT) Implementation Specifications. That is, each of these two specifications is expected to use a subset and/or superset A group of commands or functions that exceed the capabilities of the original specification. Software or hardware components designed for the original specification will also operate with the superset product. However, components designed for the superset will not work with the original. of the Definition Data described in the Recommendation Paper. Future revisions of this specification will convert the current XML Document Type Definitions (DTD (Document Type Definition) A language that describes the contents of an SGML document. The DTD is also used with XML, and the DTD definitions may be embedded within an XML document or in a separate file. ) to XML Schema. Comments regarding this Recommendation Paper should be forwarded to the OGC Coordinate Transformation Working Group at ct.wg@opengis.org. OGC is an international industry consortium of over 200 companies, government agencies and universities participating in a consensus process to develop publicly available geoprocessing specifications. OpenGIS Specifications establish common interfaces that "geo-enable" the Web and mainstream IT, enabling technology developers to make complex spatial information and services accessible and useful with all kinds of applications.
