This package offers access to the standard database structure. All defined sources are belonging directly to the so called “standard configuration”. Whenever you use a standard configuration for a topic (you configure this in your YAML see: configuration)you can find further information here. All standard sources are sub classes of the core source classes (base-sources) and the basic database source (api-pyramid_oereb-lib-sources-basedatabasesource).
All sources developed in this package are behaving the same. Besides the maybe implemented parameters for the read method of course. The main approach is to establish a session with the configured database and query it. If some error accrues it is closing the session correctly to be aware of hanging sessions.
