+## Abstract
+
+This proposal defines a standard to classify Cardano native assets by the asset name.
+
+## Motivation
+
+As more assets are minted and different standards are used to query data for these assets, it's gettinger harder for 3rd parties to determine the asset type and how to proceed with it. This standard is similar to [CIP-0010](https://github.com/cardano-foundation/CIPs/tree/master/CIP-0010), but focuses on the asset name of an asset.
+
+
+## Specification
+
+To classify assets the `asset_name` needs to be prefixed with an opening and closing parentheses and the label in betwen: `({Label})`.
+
+For example:
+
+UTF-8 encoded: `(123)TestToken`\
+HEX encoded: `283132332954657374546F6B656E`
+
+
+These are the reserved `asset_name_label` values
+
+`asset_name_label`            | description
+----------------------------  | -----------------------
+0 - 15                        | reserved\*
+65536 - 131071                | reserved - private use
+
+For the registry itself, please see [registry.json](./registry.json) in the machine-readable format. Please open your pull request against
+this file.
