@dangl/angular-ava is an UI library for Angular applications. It's used to render trees of AVA Projects. AVA in German stands for Ausschreibung, Vergabe & Abrechnung (Tendering, awarding & billing), they represent services and elements of construction projects. Additionally, it has components for displaying invoice views for e.g. the XRechnung standard for electronic invoices.
AVACloud by DanglIT GmbH is one way of creating such data structures.
