As one of the original creators of GML, Galdos Systems has significant expertise in creating schemas in the Geography Markup Language. GML application schemas provide an essential ingredient in geospatial data sharing by specifying a common language for filters, queryies, and responses.
GML schemas are the way to establish the community vocabulary in a shared application domain. Schemas and frameworks such as the Common Alerting Protocol (CAP) and the National Information Exchange Model (NIEM) are used to define specific data structures for messages in domains such as emergency management.
Sometimes, a complete GML schema is not necessary to describe the data for a domain. A GML Profile is an expression of a subset of a GMLschema that is used within a specific application domain. At other times, a GML schema may be made up of a number of sub-schemas, each of which describes a specific part of the dataset.
As one of the original creators of GML, Galdos is an active participant in the Open Geospatial Consortium (OGC), which maintains GML. Galdos is the co-chair of the OGC GML standards working group.
Additional details on various Galdos projects are available in the Case Studies.
