for efficiency reasons, DIGGS also provides a means of encoding the
ResultSet in an arbitrary external encoding, such as a binary file. This encoding
may be "well-known" but this is not required. This mode uses the diggs:ResultFile
element. The values in the dataValues element of the measurement are transmitted in
a external file that is referenced from the XML structure described by
diggs:ResultFileType. The external file is referenced by the diggs:fileReference
property that is an anyURI This means that the external file may be located remotely
from the referencing DIGGS instance. The diggs:compression property points to a
definition of a compression algorithm through an anyURI. This may be a retrievable,
computable definition or simply a reference to an unambiguous name for the
compression method. The diggs:mimeType property points to a definition of the file
mime type. The diggs:fileStructure property is defined by a codelist, but should be
"Record Interleaved" to preserve the required structure of the dataValues property,
whereby each record contains a set of fields in parameter order, with each record in
document order associated with a value, in order, in the location or timeDomain
property of the measurement. Note that if any compression algorithm is applied, the
structure above applies only to the pre-compression or post-decompression structure
of the file.
