Graham,

Coming back to one of your comments on the primer:

I agree that the primer text didn't adequately capture this. Just to
be clear we mean the same thing, entities *are* things that can
change, right? It's just that as soon as an attribute by which they
are characterised changes, then it is no longer that entity. A web
resource is an entity, even if there are also more specific
characterisations.

I found it difficult to extract the PAQ text from the web context and
seemed longer than ideal for the primer intuition section, so went
back to the DM spec and tried to work some text from there.

I tried adding some text (third paragraph) to the primer section
below. Is this adequate?

Thanks,
Simon
