[Crm-sig] Rights model

Dear Robert, Stephen,

I think these questions are too complex for an e-mail discussion. It is 
absolutely non-trivial to talk about
50% ownership. The CRM was clearly not made to describe business 
transaction in the way you mention below. That needs a careful extension 
and systematic description of the questions. We had formed a team to 
investigate business models analyzing spectrum, but the partners from 
Collection Trust dropped out later.

The first action would be to restart that work, form a team, and recover 
all arguments in the minutes.

As CRM-SIG, we are interested in robust models that we can recommend as 
standards. That requires a complete understanding of the issues.

The reasoning about owning a physical thing is very different from 
owning an Information Object. Metaphoric analogies natural language is 
built on can be very deceiving.

Any user of the CRM can make his own extensions any time. It is not a 
virtue to reuse CRM constructs for areas not intended to. That causes 
the typical mess of pseudo-compatiblity.

If we describe physical ownership as a E30 Right, we come in conflict 
with the property.

I propose to split the questions.

Martin

Ownership of an object is clearly a Right, but is it divisible with P148_has_component (via inheritance from E89)?  For example, if two Persons each own 50% of the value of an object, is there an Ownership Right, which has two component Rights, each of which have a dimension of 50% ?

For example, E30 is not “Copyright” or “Apache 2.0” or “Ownership” … it is “The holding of copyright of an object by Martin”, “the use of Apache 2.0 for some code by Rob”, or “Ownership of a house by Emma”.
