Constants for writable formats
org.openrdf.rio.RDFFormat
Represents the concept of an RDF data serialization format. RDF formats are identified by a {@link #getName() name} and can have one or more associatedMIME types, zero or more associated file extensions and can specify a (default) character encoding. Some formats are able to encode context information while other are not; this is indicated by the value of {@link #supportsContexts}. @author Arjohn Kampman
