## Guid
`<podcast:guid>`<br><br>
This element is used to declare a unique, global identifier for a podcast. The value is a UUIDv5, and is easily generated from the RSS feed url, with the **protocol scheme and trailing slashes stripped off**, combined with a unique "podcast" namespace which has a UUID of `ead4c236-bf58-58c6-a2c6-a6b28d128cb6`. Tools like [this one](https://www.uuidtools.com/v5) can help generate these values by hand. Or, language libraries like [this one](https://github.com/sporkmonger/uuidtools) in Ruby are widely available.

Specifically for podcasts, [this tool from RSS Blue](https://tools.rssblue.com/podcast-guid) can help generate a GUID by hand.
A podcast gets assigned a podcast:guid once in its lifetime using its current feed url (at the time of assignment) as the seed value. That GUID is then meant to follow the podcast from then on, for the duration of its life, even if the feed url changes. This means that when a podcast moves from one hosting platform to another, its podcast:guid should be discovered by the new host and imported into the new platform for inclusion into the feed.
