|---|
The purpose of this specification is to precisely document the
syntax and semantics of the XML format that is used to communicate
between the Config4GNU subsystem and the underlying configuration
file parsers.
- Config4GNU subsystem
Also known as the "middle layer," this component of the
Config4GNU system exists in between the front-ends and the
back-ends. It provides routines that are common to all
front-ends so that code does not need to be duplicated.
It automatically invokes the necessary back-ends when
configuration files need to be read or written.
- Configuration file parsers
Also known as the "back-ends," these programs read and/or
write native-format configuration files. They translate
between a standard XML format, which is described in this
document, and the native format of the configuration file.
They are automatically invoked by the middle layer as needed.
- Nodes
Identifies some aspect of the configuration. It is a location
on the configuration hierarchy that Config4GNU presents to
the user. As part of a hierarchy, it has one "parent" node
and zero or more "child" nodes. Is also composed of
properties.
- Property
This is one configuration setting. Properties are attached
to a configuration node. Properties are composed of a name
and a value.
