We have a longstanding issue (partially cleaned in #806) due to the choice of naming for the type Physician, which represents "a doctor's office" and has a variety of supertypes:

• Thing > Organization > LocalBusiness > MedicalBusiness > Physician
• Thing > Place > LocalBusiness > MedicalBusiness > Physician
• Thing > Organization > MedicalOrganization > Physician

The current poor typing as a LocalBusiness (via MedicalBusiness) brings in the subtype of Place. In #806 we decoupled MedicalOrganization from this hierarchy (although note that such organizations can have an address). We should continue this cleanup by removing the assertion that a Physician is a MedicalBusiness, leaving it typed just as a MedicalOrganization. For association with places we can draw attention to the address and hospitalAffiliation properties, with potential to add /practicesAt for more specificity and to cover clinics etc.

Changes

1.) remove: Physician subClassOf LocalBusiness.

2.) Reword definition. Instead of "A physician's office", something like:

An individual physician, considered as a [[MedicalOrganization]]. For their official address use [[address], for affiliations to hospitals use [[hospitalAffiliation]]. The (todo) [[practicesAt]] property can be used to indicate [[MedicalOrganization]] hospitals, clinkics, pharmacies etc. where this physician practices. If there is a need to describe the physician as a [[Person]], the [[founder]] property can be used.

3.) add /usNPI, a /Property whose value is /Text (using /Number doesn't add much here); domainIncludes /Physician.

A US NPI (National Provider Number) is a unique 10-digit identification number issued to health care providers in the US.

4.) Add /practicesAt, a /Property whose value is a /MedicalOrganization; domainIncludes /Physician.

Definition:

Indicates a medical organization where this physician practices.
