Configuration Data Storage using GConf
[1] Software Architecture Document, Version 1.1 Revision 1.4, LiMo Foundation, 11 September 2007
LiMo Foundation Platform Release 1 uses GConf from the Gnome Project for configuration data storage and retrieval. GConf provides a simple configuration data storage interface to applications. Some of the features of GConf include:
- Replaceable backend architecture: GConf currently has a single backend that stores configuration data in XML-format text files. However, the architecture allows a Registry-like binary database backend, an LDAP backend or even a full-blown SQL database backend.
- Configuration key documentation: Applications can install documentation along with their configuration data, explaining the possible settings and the effect of each configuration key.
- Data change notification service. All interested applications can be notified when configuration data changes. This means that applications built from components (where each component may be in a separate process) are much easier to write because if one component changes a setting the other components can discover the change and update themselves.
- Abstract client API: Allows changes to the underlying implementation without requiring changes to applications.
- Access locking: Protects configuration data from corruption when multiple applications try to access the data simultaneously.
