GML Schema Development
Galdos has worked with the United Kingdom Ministry of Defence on several projects involving the development of GML Application schemas for both GML 3.1.1 and GML 3.2 for AML 2.1, VMap 0, 1, 2 as well as DAFIF (UK version).
The schemas were loaded into the Galdos Cartalinea Web Feature Service (on X-Hive, a native XML database; Oracle Spatial; and ArcSDE on Oracle) and populated with sample data. The GML data was then propagated (using Web Feature Service (WFS) transactions) to other WFS instances, each of which utilized different back end databases (e.g. ArcSDE, Oracle Spatial) thus making it possible to freely exchange data amongst different databases.
This proved that using WFS to disseminate DAFIF, AML, and VMAP is a viable and effective method. Galdos has subsequently created basic SLDs and has deployed the Galdos FreeStyler Feature Portrayal Service (FPS) which uses these SLDs to visualize data being drawn from a WFS.

Galdos produced a high level architecture study outlining how OGC based web services fit into the broader military environment. This study showed how OGC web services and the broader Service Oriented Architecture (SOA) could be implemented in an operational military environment.
