Requirement Specification of an Information Bank

An information bank is a data storage solution where users can store data they own. Nowadays our data are scattered over the internet stored by large companies, government agencies, or simply lost. Sooner or later there will be information banks that offer free or at least cheap solutions to store our data, the data owned by ourselves. The main use case is the following: Mr. X buys a sofa and gets a PDF file which describes how to clean the sofa. Mr. X. uploads this PDF to his information bank account. Then, after 3 years of using the sofa, he split some coffee on it. He completely forgot how to clean his sofa, but he knows that most probably he uploaded the corresponding information to his information bank account. So, he logs into his account and asks a Large Language Model-based artificial intelligence trained on his data how to clean his sofa. He should not check the name of the sofa, since he owns only one, so the AI understands that he is looking for the information from the ‘how to clean the XYZ sofa’ PDF. We collect use cases and requirements relevant to designing such an information bank.
