@ualbertalib/metadata-team, if a collection doesn't have a description, can I leave it out of the AIP?

Another related question. If a collection description contains markdown, should the AIP contain the markdown, how it would render as HTML, or should that markdown be stripped so that the AIP description is just plain text?

MARKDOWN = <<~MARKDOWN.freeze
  **Itaque _est_** ~~incidunt~~. Magnam *repellendus* id. Eos qui **voluptatem**.

  Here's a line for us to start with.

  This line is separated from the one above by two newlines, so it will be a *separate paragraph*.

  This line is also a separate paragraph, but...
  This line is only separated by a single newline, so it's a separate line in the *same paragraph*.

  [I'm an inline-style link with title](https://www.google.com "Google's Homepage")

  URLs and URLs in angle brackets will automatically get turned into links.
  http://www.example.com or <http://www.example.com> and sometimes
  example.com (but not on Github, for example).

Thanks @pgwillia If there is no description then it can be left out. In terms of the markdown, what we really want here is the content as opposed to the display per se. That said, if there is a link to something external it would be ideal to be able to keep the url even if it doesn't display as a hyperlink. Hope that helps!

[pgwillia]

@sfarnel Thanks for the quick response!

I'm hearing that we want the content, including the links. The best solution that matches this is the first example with what the user creates as the description for the collection, not what the user sees on the collection page. If it's okay I'll go with this.
