The project will realize a .NET/Angular based custom software for receiving, managing and distributing documents. Integrated via webservices and file systems into an existing environment, it manages, sorts, aggregates and coagulates documents based on user-defined rules. Metadata of documents are received, validated, managed, and distributed as well. Users can perform role-dependent configurations and request specific collective output of the documents. Thereby, configurable user authorization defines the accessibility of data and application functionality. The output takes place in collective files that contain sorted and summarized documents according to the configurations, which have been additionally provided with generated cover letters and table of contents. Furthermore, validations and checks with data comparison of several master data systems are realized, which technically and functionally check the documents as well as their collective output.
