Jack,

*try again, with minor changes*

Your original request centred around the IPTC 'PersonInImage' tag. At 
present DigiKam does not allow this IPTC 'PersonInImage'tag to be 
changed, although if the value is set using other tools you can see the 
value in the metadata section of the right panel.

What Erik is describing is an alternative approach used by many on this
list -- the use of Keyword Tags to flag who is in the picture.

Essentially you can create a Keyword Tag for each unique entity and 
check these Keyword Tags if the person is seen in the picture (see 
manual on how to create tags). These Keyword Tags can also be easily 
used to filter your collection to show, say all photos with your Mum in it.

If you are hung up on using the IPTC 'PersonInImage' tag you may wish to 
look at exiv2 on linux or exiftools on Windows/Mac. These 
tools/libraries are able to set this value. All you would need to do is 
set the value using a script of sorts depending on your operating system.

exiv2 -- http://www.exiv2.org/
exiftools -- http://www.sno.phy.queensu.ca/~phil/exiftool/

According to exiv2 manpage the value PersonInImage can be set using the
following command (I check this worked on Ubuntu)...

exiv2 -M"add Xmp.iptcExt.PersonInImage Mr Periwinkle" image.jpg

You will need to check with the packages you normally use whether this 
is going where you/they expect. When I inspect this image in digiKam the 
inserted value is in the "IPTC Extension schema" where the standard says 
it should be -- as stated although showing the value inserted I can not 
edit the data with digiKam.

http://www.exiv2.org/manpage.html
http://www.exiv2.org/tags-xmp-iptc.html
http://www.exiv2.org/tags-xmp-iptcExt.html

I hope this helps.
