The OGC is requesting review of a proposed GML MIME type. Below is the application formatted using the registration form. Thank you for your time and consideration. Carl Reed, PhD CTO OGC Type name: Application Subtype name: Standards Tree gml+xml Required parameters: None Optional parameters: "charset" The charset parameter of application/gml+xml is handled in the same fashion as for application/xml, as specified in Section 3.2 of [RFC3023] "version": If provided, this parameter indicates the GML version used in the GML document. Only the major and the first minor version number are provided, e.g. "3.2". The value may be provided with or without quotes. i.e., application/gml+xml; version=3.1 shall be treated as identical to application/gml+xml; version="3.1". In cases where elements from multiple GML versions are used, the parameter shall indicate the highest GML version used in the document. The parameter can be used to provide protocol-specific operations, such as version-based content negotiation in HTTP or in the OGC Web Feature Service. Encoding considerations: As per Section 3.2 of [RFC3023] Security considerations: The OGC Geography Markup Language (GML) is a generic format for exchanging geographic information, but application designers must not assume that it provides generic protection against security threats. RFC 3023, section 10, discusses security concerns for generic XML, which are also applicable to GML. Xlink references in GML documents may cause arbitrary URIs to be dereferenced. In this case, the security issues of RFC 3986, section 7, should be considered. Interoperability considerations: Different versions of GML specify different XML Schema documents used for the validation of GML documents. Starting with version 3.2, the GML version information is represented in the namespace. As applications may only support a subset of all published GML versions, the use of the version parameter is recommended. Published specification : GML (Geography Markup Language) is an international standard adopted by both the Open Geospatial Consortium (OGC) and International Organization for Standardization (ISO). The latest version at the time of this writing is 3.2.1 which is published by ISO as ISO 19136:2007. The standard can be accessed freely online at http://www.opengeospatial.org/standards/gml. The OGC GML MIME specification has also been approved by the OGC Membership and is published here: http://portal.opengeospatial.org/files/?artifact_id=37743 Applications which use this media type: GML is a generic device-, platform-, and vendor-neutral XML grammar and is supported by a range of applications creating, providing access to and processing geographic information. The use of GML is in use internationally with hundreds of deployed applications able to create and ingest GML payloads, including all of the major GIS vendors, many database providers, earth browzer applications, and so forth. Additional information: 1. Magic number(s): None. Although no byte sequences can be counted on to consistently identify GML documents, GML documents will have the sequence http://www.opengis.net/gml as part of a namespace declaration to identify the GML namespace. This will usually be towards the top of the document. 2. File extension(s): .xml or .gml 3. Macintosh file type code: TEXT 4. Object Identifiers: None The OGC is an international voluntary consensus standards organization focused on defining and maintaining standards that enable interoperability for using geospatial content and services in any application that requires the use of geospatial content or services. The OGC website is www.opengeospatial.org. Person & email address to contact for further information: Name : Clemens Portele Address:Interactive Instruments, Bonn, Germany Email : portele@interactive-instruments.de Intended usage: Common Restrictions on usage: None Author/Change controller: The GML standard is a work product of the Open Geospatial Consortium (OGC). The OGC and the GML Standards Working Group have change control over the GML standard. MIME types for use in OGC standards and formats are defined by the OGC Members and discussed and approved by the OGC Naming Authority (OGC-NA). The function and role of the OGC-NA is described in RFC 5165 and in the OGC Policies and Procedures here: http://portal.opengeospatial.org/files/?artifact_id=23325 Carl Reed, PhD CTO and Executive Director Standards Program Open Geospatial Consortium www.opengeospatial.org The OGC: Making Location Count! --------------------- This communication, including attachments, is for the exclusive use of addressee and may contain proprietary, confidential or privileged information.
