The digiKam source code is huge.
start to use the application before to play with code. Import image and look how metadata are parsed and stored in database. It's mostly done in imagescanner.cpp
Look also the properties of items registered in DB. It's mostly available through imageinfo.cpp.
The items info from DB are visible by right sidebar from AlbumGUI. Look properties tabs.
The main features of digiKam is the capability to search items, all based on DB. From left sidebar of album GUI, look Date view, TimeLine, Geolocation, and Advanced search (which is the most powerfull tool).
All these view are implemented in core/utilities.
