Constants.RdThe package sos4R comes with a set of constant character strings and fixed supported features, for example for names of XML elements, XML Namespace prefixes, or supported formats and models.
Most of these variables should be pretty self-explanatory.
Constants for names of XML elements start with a lowercase character string of the namespace prefix (e.g. "gml"), a unique name of the element (where parts like "type" and special characters may be left out, and other descriptive elements may be added for clarity), and end with "Name".
Examples: codegmlEnvelopeName, ogcGeometryOperandLineStringName, ogcTempOpTMEqualsName.
The OwsExceptionsData() function provides access to the fixed exception codes, meanings and respective HTTP codes and messages.
The mime types are used for automatic detection of the best fitting parser.
See also Defaults for default parameter settings.
