How to add a hyperlink
If you would like to include a hyperlink in your metadata, you will need to format it with an anchor tag <a>.
In the example below, the anchor tag begins with: <a href= and ends with >>. In between the >> at the end is where you will insert your display text.
The link URL follows the href= and as shown below the bolded section represents what the user will see.
<a href=https://archive.org/details/ScreenlandDec1923>Internet Archive</a>
https://archive.org/details/ScreenlandDec1923 represents the webpage url you want to link out to and Internet Archive represents the text that is represented in the LUNA Viewer's data panel.
