What is GML

1.

The Geography Markup Language is a XML grammar defined by the Open Geospatial Consortium (OGC) to adequately express and transfer, in a neutral way, the encoding of geographic features. Its purpose is to foster the integration of geographic data sources. Learn more in: Spatial Data Infrastructures

2.

The Geography Markup Language is a XML grammar defined by OGC to express geographical features. To help users and developers to structure and facilitate the creation of GML-based application, GML provides GML profiles that are XML schemas that extend the very GML specification in a modular fashion. A GML profile is a GML subset for a concrete context or application but without the need for the full GML grammar, simplifying thus the adoption of GML and facilitating its rapid usage. Some common examples of GML profiles that have been published are Point Profile, for applications with point geometric data, and GML Simple Features profile, supporting vector feature requests and responses as the case of WFS.
