Clarify 'resource role'

[mbrush]

The 'resources role' is defined from the perspective of a project or publication to which an agent provides a research resource: "Provision of study materials, reagents, materials, patients, laboratory samples, animals, instrumentation, computing resources, or other analysis tools".

If I want to capture the fact that an agent was the creator of a physical resource, e.g. a transgenic mouse, what role would I use? The 'resources role' doesn't fit because it describes the provision of the resource as opposed to its creation. There is no generic 'creator role', nor are there more specific roles describing contributions to physical artifacts - as there are for contributions to software, data artifacts, and publications in the 'data role', 'software role', and 'author role' hierarchies, respectively.

Some thought needs to go into how to support such use cases, and how to treat roles around generation of physical resources in relation to how we have treated roles around informational resources.
