The MMDA allows the users to name, annotate, store, and organize collections of data files into data aggregates called Data-Aggregates (DAGR for short). A DAGR may contain an arbitrary number of multimedia files, e.g. text documents, images, audio, video, and other previously created DAGRs.

• Clone or download the project
• Run npm install from the project's root directory

• Run npm start
• Navigate to localhost:3000 or 127.0.0.1:3000 from your preferred browser

Environment Variables

To setup the evironment variables for the DB connection you will have to create a .env file in the root directory using the following template:

DB_USERNAME=[YOUR_USERNAME]
DB_PASSWORD=[YOUR_PASSWORD]
DB_CONNECTSTRING=[YOUR_CONNECT_STRING]

Ask your DB admin for your specific credentials.
