1.4 The XML Documents
1.4.1 Documents
The XML Data in the TANDBERG systems are divided into three main types of documents.
The division is based on whether the information is Read Information, Write Information or
Read-Write information:
1. Status documents (r): Documents holding all available Status Information in the
system.
Supported documents:
a. status.xml
b. history.xml
2. Configuration documents (rw): Documents holding all system configurations.
Supported documents:
a. configuration.xml
b. directory.xml
3. Command documents (w): Documents defining the supported system commands
used to initiate system processes. This is write data, i.e. the parameter values for a
given command are defined by the user and posted to the system. The posted values
will not be returned when reading the document from the system. Reading a
command document from the system returns descriptions of the supported
commands with empty parameter values.
Supported documents:
a. command.xml
4. Meta Documents: Meta documents contain information that can be referenced by
other documents, e.g. value domains of configurations or command parameters.
Supported Meta Documents:
a. valuespace.xml
1.4.2 Status Documents (r)
The Status Documents are characterised by an extensive use of XML attributes. In addition to
holding information, the attributes are used to reflect the structure of the sub-elements, which
are dependent on the state of the system.
