This project involves the development of an open source database to enable the linked exploration of data in the platform, including energy demand, supply and technology data. Data in the HUES platform is highly diverse and rapidly growing. Currently, this data is stored in separate platform modules using different data structures and file formats, making it difficult to explore holistically. We will migrate this data using a tool Mongify to migrate database from MySQL to MongoDB. The development of server based scripts to automatically extract relevant data from the modules of the HUES platform, and write this data to a common database. In the new database everything can be retrieved in the form of JSON objects. The development of a web-based portal for querying, visualizing and downloading data will be the last part of the project development.
