RE: [obix-comment] Contract inheritance

["Brian Frank" <bfrank@tridium.com>]

The root's href should not be inherited because it is the public
identifier for the contract.

But I think your question is related to the children of the root,
perhaps something like this:

  <obj href='Person'>
    <str name='firstName' href='firstName'/>
    <str name='lastName' href='lastName' />
  </obj>

Is that what you are asking - such that instances of Person inherit the
hrefs for firstName and lastName?

I think I like that, although the major downside is that it requires all
implementations of the contract to support addressing down to the
children. 
Personally I think of href as part of the "value side" rather than the
"contract side" because it's a server implementation detail.

What was the rationale for not inheriting href's in contracts?  Since
the
non-root href's will be relative, it would seem to simplify matters if
they
were inherited.  That way derived types would not have to override
elements
simply to assign/reassign href's.
