Editing Geography Markup Language (section)

===Towards ISO – GML 3.0 broadens the scope of GML===
While a basic coding existed for most of the new objects introduced by the GML/G-XML agreement, and for some introduced by Galdos within the [[Open Geospatial Consortium|OGC process]] (notably coverages), it soon became apparent that few of these encodings were compliant with the abstract specifications developed by the ISO TC/211, specifications which were increasingly becoming the basis for all OGC specifications.  GML geometry, for example, had been based on an earlier and only partly documented geometry model (Simple Features Geometry) and this was insufficient to support the more extensive and complex geometries described in TC/211.  The management of GML development was also altered in this time frame with the participation of many more individuals. Significant contributions in this time frame were made by Milan Trninic (Galdos) (default styles, CRS), Ron Lake (Galdos) (Observations), Richard Martell (Galdos) (dynamic features).

On June 12, 2002, Mr. Ron Lake was recognized by the OGC for his work in creating GML by being presented the Gardels award.<ref>{{Cite web|url=http://portal.opengeospatial.org/files/?artifact_id=9477|title=award citation for Ron Lake}}</ref> The citation on the award reads “In particular, this award recognizes your great achievement in creating the Geography Markup Language, (GML), and your uniquely sensitive and effective work to promote the reconciliation of national differences to promote meaningful standardization of GML on a global level.” Simon Cox (CSIRO)<ref>{{Cite web|url=http://portal.opengeospatial.org/files/?artifact_id=16038|title=award citation for Simon Cox}}</ref> and Clemens Portele (Interactive Instruments)<ref>{{Cite web|url=http://portal.opengeospatial.org/files/?artifact_id=22940|title=award citation for Clemens Portele}}</ref> also subsequently received the Gardels award, in part for their contributions to GML.
