A role in which the playing entity (material) provides access to another entity. The principal use case is intravenous (or other bodily) access lines that preexist and need to be referred to for medication routing instructions.

A physical association whereby two Entities are in some (even lose) spatial relationship with each other such that they touch each other in some way.

Examples: the colon is connected (and therefore adjacent) to the jejunum; the colon is adjacent to the liver (even if not actually connected.)

UsageConstraints: Adjacency is in principle a symmetrical connection, but scoper and player of the role should, where applicable, be assigned to have scoper be the larger, more central Entity and player the smaller, more distant, appendage.

An adjacency of two Entities held together by a bond which attaches to each of the two entities.

Examples: biceps brachii muscle connected to the radius bone, port 3 on a network switch connected to port 5 on a patch panel.

UsageConstraints: See Adjacency for the assignment of scoper (larger, more central) and player (smaller, more distant).

A connection between two atoms of a molecule.

Examples: double bond between first and second C in ethane, peptide bond between two amino-acid, disulfide bridge between two proteins, chelate and ion associations, even the much weaker van-der-Waals bonds can be considered molecular bonds.

UsageConstraints: See connection and adjacency for the assignment of player and scoper.

A connection between two regional parts.

Examples: the connection between ascending aorta and the aortic arc, connection between descending colon and sigmoid.

UsageConstraints: See connection and adjacency for the assignment of player and scoper.

A material (player) that can be administered to an Entity (scoper).

Relates a place (playing Entity) as the location where a living subject (scoping Entity) was born.

Definition: Relates a place (playing Entity) as the location where a living subject (scoping Entity) died.

A material (player) distributed by a distributor (scoper) who functions between a manufacturer and a buyer or retailer.

Material (player) sold by a retailer (scoper), who also give advice to prospective buyers.

A role played by a place at which the location of an event may be recorded.

A role played by a place at which services may be provided.

A role of a place (player) that is intended to house the provision of services. Scoper is the Entity (typically Organization) that provides these services. This is not synonymous with "ownership."

A role played by a place at which health care services may be provided without prior designation or authorization.

A role played by an entity that has been exposed to a person or animal suffering a contagious disease, or with a location from which a toxin has been distributed. The player of the role is normally a person or animal, but it is possible that other entity types could become exposed. The role is scoped by the source of the exposure, and it is quite possible for a person playing the role of exposed party to also become the scoper a role played by another person. That is to say, once a person has become infected, it is possible, perhaps likely, for that person to infect others.

Management of exposures and tracking exposed parties is a key function within public health, and within most public health contexts - exposed parties are known as "contacts."

Entity that is currently in the possession of a holder (scoper), who holds, or uses it, usually based on some agreement with the owner.

The role of a material (player) that is the physical health chart belonging to an organization (scoper).

A role in which the scoping entity designates an identifier for a playing entity.

Scoped by the manufacturer

A manufactured material (player) that is used for its therapeutic properties. The manufacturer is the scoper.

An entity (player) that is maintained by another entity (scoper). This is typical role held by durable equipment. The scoper assumes responsibility for proper operation, quality, and safety.

An Entity (player) for which someone (scoper) is granted by law the right to call the material (player) his own. This entitles the scoper to make decisions about the disposition of that material.

A product regulated by some governmentatl orgnization. The role is played by Material and scoped by Organization.

Rationale: To support an entity clone used to identify the NDC number for a drug product.

Relates a place entity (player) as the region over which the scoper (typically an Organization) has certain authority (jurisdiction). For example, the Calgary Regional Health Authority (scoper) has authority over the territory "Region 4 of Alberta" (player) in matters of health.

**Description:**An entity (player) that is used by another entity (scoper)

A role a product plays when a guarantee is given to the purchaser by the seller (scoping entity) stating that the product is reliable and free from known defects and that the seller will repair or replace defective parts within a given time limit and under certain conditions.
