# Additional Attributes Specification

In addition to current fields available for specifying attributes, Solflare will integrate additional fields for describing attributes.

#### Some of them are:

* `display_type: "Date"` - will display the `value` as a date, use a unix timestamp to specify it
* `max_value: Number` - if the `value` is also a number, it will be displayed as a bar chart with a maximum value
* `trait_count: Number` - if the asset is part of a collection, this number represents the total count of other assets with the same trait type and value

The only mandatory fields to describe an attribute are: `trait_type` and `trait_value`.
