# How to Add and Edit Metadata and Tags
## Metadata
### 1. Adding a Metadata Entry
On both the Collection Taxonomy and Asset Specific Taxonomy tabs, Click the button to add a data entry to it. Fill in the `key` and `value` fields in the newly-created row, and click the button when you’re done or click to cancel.
{% hint style="info" %}
You can add almost **any key** and **any value**. However, there are a few reserved metadata keys that cannot be added or edited.
{% endhint %}
{% embed url="" %}
On the Collection Taxonomy tab you can also tick the checkbox to apply the metadata entry to **all assets individually.**
{% embed url="" %}
### 2. Adding Multiple Data Entries
Click the three dots and "Upload CSV" to upload a **.csv** file that contains pairs of keys and values to be added as data entries to the global database. Your metadata file should contain only two columns: one for **keys** and the second for **values**.
Here is a sample file you can use:
{% file src="/files/-M9tGw0oesRNMKmCPf0\_" %}
### 3. Editing a Data Entry
Click on the button to edit the data entry. Click the button when you’re done or click to cancel.
### 4. Deleting a Data Entry
Click on the button to delete the data entry and confirm the deletion, when prompted. Be sure to delete the metadata from all assets, if you added it for both the collection and for each asset individually.
### 5. Downloading All Data Entries
Click the three dots and click "Download CSV" to download a **.csv** file that contains pairs of keys and values representing the global database.
### 5. Required Keys
Admins also have a "Required Keys" database, allowing them to set keys that all other users must add to new assets added to the collection. Adding, editing and deleting required keys are done in the same manner as in the Metadata Database. Uploading and downloading csv files and locking the database or deleting all required keys is also done in the same manner as in the Metadata Database (clicking the three dots).
## Tags
You can add tags to both collections and specific assets. You can manually add any tag to your asset or collection, and the platform will also suggest other relevant tags for your to include.
If enabled on upload, the platform will use AI to auto-generate tags and add them to your asset. You can then manually add more tags to your asset or your collection. AI-generated tags looks like this (and can be removed like any other tag):
