Field Content Tags

Tags give extra meta-information about what a field stores

Content tags

We keep the data types to just a few and use tags to note types of content which should be handled specially.

Example: Email

If you want to store an Email in a field, it makes sense for that field to be a text field.

But when emails are presented to the user, it makes sense that they are not just presented simply as text - ideally there should be some indication that this is an email, and perhaps the UI should afford the user of clicking on the email to open a mail client.

This is how you tag a field to denote that it is an email field
