Defining digital identity

Here is something I have come up with in my quest for the definition of digital identity. This is only a working definition and all comments and suggestions are welcome.

"Digital identity refers to any digital representation (whole or partial)
of an entity,
in tangible or abstract form,
either self-created,
externally assigned
or consequentially generated."

Watch this space.
