 In the command line, navigate to the directory where this repository is stored on your local machine and run:
 
-`docker-compose up -d --build`
+`docker compose up -d --build`
 
 Docker should build the application environment comprising a Python container running Flask and a database container running MariaDB.
 
 
 To take down the environment, run:
 
-`docker-compose down`
+`docker compose down`
 
 ### populating the database
 
 To intially create the database and a database user:
 
-`docker-compose exec -it db mariadb -u root -p`
+`docker compose exec -it db mariadb -u root -p`
 
 Enter your root password as defined in .env.dev.
 
 
 Restart the containers to allow Flask to build the database tables:
 
-`docker-compose down`
-`docker-compose up -d --build`
+`docker compose down`
+`docker compose up -d --build`
 
 You can then use database_functions.sh and an SQL file to populate the database e.g.
 

web/app/models.py

     # all resource types
     id = db.Column(db.Integer, primary_key=True) # primary keys are required by SQLAlchemy
     created = db.Column(db.DateTime, default=datetime.utcnow)
+    updated = db.Column(db.DateTime, onupdate=datetime.utcnow)
     published = db.Column(db.Boolean)
     type = db.Column(db.Text)
     name = db.Column(db.Text)
     description = db.Column(db.Text)
-    videoUrl = db.Column(db.Text)
     # tools
     developer = db.Column(db.Text)
     developerUrl = db.Column(db.Text)
     bookUrl = db.Column(db.Text)
     isbn = db.Column(db.Text)
     typology = db.Column(db.Text)
+    # all
+    videoUrl = db.Column(db.Text)
 
 # table for relationships
 class Relationship(db.Model):
