You may want to work with your team to define your set of badges and how you intend for them to work in Canvas using module completion requirements before creating badges. For easy collaborative system design discussions, you can download and use the Badgr Simple Learning Pathway Worksheet (XLSX).
Tags are like keywords. They may be added badges to help locate and sort badges more easily by topic; especially when using Badgr Pathways. Examples include things like programming, open-source, bit-coin, volunteer, hand-crafted, dogs, astronomy, etc. Additionally, tags will only be comprised of lowercase characters.
Users may add an expiration date when authoring a badge. The expiration date is relative to the badge award date. For example, if the badge is created with a 1 month expiration, if awarded January 1, the badge will expire February 1. If the same badge is awarded March 1, it will expire April 1.
This feature is useful, for example, if you have a certificate program where the certificate is valid for 2 years and applicants can take an online test any day of the year to qualify. The day they pass the test, they can be awarded a badge that will expire in exactly 2 years.
