Acessing data file by name of parent folder

support

Given this example from the docs:

<div>Short Description of {{.Site.Data.User0123.Name}}: <p>{{ index .Site.Data.User0123 "Short Description" | markdownify }}</p></div>
How can I make “User0123” a variable that gets the value of the current Section?

So that when I display http://www.example.com/peter/

I get the values from tha data file peter.yaml

TIA
