Custom Edit form prepopulated with existing values

[Samantha-Jane McNally]

How can I bring up custom forms to edit previous values? 

eg. I have a custom form that displays fields for the following properties:

Acronym - skos:altlabel

Definition - skos:definition

Source - dct:type

Context - dct:subject

Once these have been added to the concept, I have a view that shows these properties in a table view when added.

I would like to be able to edit each row individually using the same custom form I used to enter the values, with the only difference being I would like it to already have the values prepopulated when i launch to edit the row. 

Is this possible?

Hope this makes sense!

Thanks in advance for your time
