Web application for labeling documents generating RDFa and TEI output, developed for the digital edition of Aldo Moro opera omnia.

The project is build on the database management system Mongo.

First you need to create a Mongo collection where there has to be at least two tables: one named users for saving users, and another named metadata for stored the metadata information of every marked up document.

To set up MongoDB inside the project you need to create a .env file in order to store the connection information.

Inside the file you need to declare a DB_CONNECT variable assigning the url for your Mongo collection.

DB_CONNECT = mongodb+srv://"username":"password"@"clustername"-rwpos.mongodb.net/"collection"?retryWrites=true&w=majority

For the authentication management we use the JSON Web Token standard.

The encryption is based upon three parts:

• Header
• Payload
• Signature

The header typically consists of two parts: the type of the token, which is JWT, and the signing algorithm being used, such as HMAC SHA256 or RSA.

The second part of the token is the payload, which contains the claims. Claims are statements about an entity (typically, the user) and additional data. We store here the information about the username.

To create the signature part you have to take the encoded header, the encoded payload, a secret, the algorithm specified in the header, and sign that.

The secret object will be store inside the .env file in the variable TOKEN_SECRET.

TOKEN_SECRET = tH1s_1s_An_eXAmpl3_0F_SEcreT_String

First you need to install Node.js in your computer following the how to install guide from the official web site (https://nodejs.org/en/download/package-manager/ "Node.js").

From the terminal install all dependencies inside package.json using the node packet manager called npm.

npm install

Start the server on localhost:3000

npm start

It will execute node index.js to start the server.

To execute it on developer mode, run the following command

npm run dev

This time is going to run nodemon a tool that will restart automatically the server when an edited file is saved.

KwicKwocKwac will run on localhost:3000

Inside the doc folder there is a complete documentation of the application accessible also from the documentation button in the app menu.
