HARTS does not include an enterprise view and only a limited viewpoint specification. The only enterprise construct included is implicit: the Enterprise Object, which can be an institution, consortium, agency, corporation or individual, bounds the scope of a physical object. A single enterprise object will own an instance of a physical object. Similarly, a single enterprise object might operate, maintain, install, certify or regulate a physical object. Specific enterprise objects are not defined in HARTS, but the physical objects are scoped with these enterprise roles in mind.
