OGC Invites Comment on GML Simple Features Specification Profile.WAYLAND, Mass. -- The Open Geospatial Consortium The Open Geospatial Consortium (OGC) is an international voluntary consensus standards organization. In the OGC, more than 330 commercial, governmental, nonprofit and research organizations worldwide collaborate in an open consensus process encouraging development and 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. ) invites public comment on a candidate specification that will soon be presented for approval by OGC members as an OpenGIS(R) Implementation Specification Profile. The OGC candidate specification, "GML GML Geography Markup Language (XML components for encoding geospatial data) GML Greek Mythology Link (website) GML Generalized Markup Language simple features profile" is available for downloading from http://www.opengeospatial.org/specs/?page=requests&request=rfc22. Comments can be submitted to gmlsf-rfc@opengeospatial.org during a thirty-day public review period ending August 4th, 2005. Comments received will be consolidated and reviewed by OGC members for incorporation into the proposed specification. The 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. (TM) (GML) is an XML grammar for the encoding of geographic information. The GML simple features profile defines a restricted profile of GML that allow simple features, such as points, lines, and polygons, to be described using GML application schemas Geography Markup Language provides the basis for domain- or community-specific "Application Schemas", which in turn support data interoperability within a community of interest. Application schemas are normally designed using ISO 19103 conformant UML, and then the GML Application created . This profile specification defines rigid coding patterns for the use of a subset of XML Schema constructs (XML Schema profile) and rigid coding patterns for the use of a subset of GML constructs (GML profile). It prescribes the encoding of GML application schemas in sufficient detail that client applications do not need to deal with the entire scope of XML-Schema and GML but only need to accommodate a restricted subset of both specifications in order to be able to interpret schema documents generated by servers offering data encoded in GML. Easier interpretation of GML application schemas will enhance interoperability between clients and servers and make the task of implementing client applications easier. The following organizations submitted the draft specification for consideration: Cadcorp Ltd. (UK), CubeWerx Inc. (Canada), ESRI (Environmental Systems Research Institute, Inc., Redlands, CA, www.esri.com) The world's leading developer of geographic information systems (GIS) software, including programs that plot ZIP codes and addresses, demographic information and detailed, color-coded data. (USA), Galdos (Canada), Interactive Instruments (Germany) and PCI (1) (Payment Card Industry) See PCI DSS. (2) (Peripheral Component Interconnect) The most widely used I/O bus (peripheral bus). Geomatics (Canada). BAE Systems (USA), CSIRO CSIRO Commonwealth Scientific & Industrial Research Organization (Australia) (Australia), and the US Census Bureau also contributed to the effort. OGC is an international industry consortium of more than 280 companies, government agencies and universities participating in a consensus process to develop publicly available interface specifications. OpenGIS(R) Specifications support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. The specifications empower technology developers to make complex spatial information and services accessible and useful with all kinds of applications.
