I added another short video of a demonstration of tags used in the Didget Management System.

This video emphasizes the creation of tags and attaching them to a set of Didgets so that we can query based on them or create lists (e.g. Albums) from the query results.
Each Didget can have up to 255 different tags attached to it. There can be tens of thousand of different tags to choose from and each tag value can be a string, a number, a boolean, or other value type. We have a set of predefined tags such as .event.Holiday, .date.Year, and .activity.Sport but the user is free to define any additional tags and immediately begin attaching them to any Didget.
Attaching tags to Didgets and performing queries based on them, works exactly the same way for photos, documents, music, videos, or any other type of Didget.
