The Actor archetype is highly generic You can capture data for individual actors either
by using softcoded values (see Chapter 13) or by creating specific entity types as this chapter does for customer (Section 10.7) and vendor (Section 10.20)
10.3 Address
An Address is a means for communicating with an Actor (Figure 10.5, Figure 10.6) An ad-dress can be a postal adad-dress, email adad-dress, phone number, or URL An adad-dress can serve
various purposes (AddressRoleTypes, see Section 10.18) such as shipping, billing, business,
and home Thus the same address might be used both as a business address and a home ad-dress
10.4 Asset
An Asset is something of value (Figure 10.7, Figure 10.8) An OwnedAsset is an asset that
is owned outright A RentedAsset is the use of an OwnedAsset for some time period Thus, for example, a bicycle that is owned is an OwnedAsset A bicycle that is rented for some time period is a RentedAsset An OwnedAsset may or may not be individually identified — if an OwnedAsset lacks identity, AssetOwnership can involve a multiple quantity.
For another example, consider a timeshare The underlying property is an OwnedAsset The timeshare itself is a RentedAsset available for some time interval Timeshares can be
is-sued for a particular unit but are often tradeable and substitutable by a comparable unit

Trang 210.5 Contract
A Contract is an agreement for the supply of products (Figure 10.9, Figure 10.10) (Section
10.17 discusses Product.) Many Actors (various persons and organizations in a variety of
roles) can participate in a contract Businesses use contracts as a means for conducting

10.6 Course
A Course is a series of lessons about a subject (Figure 10.11, Figure 10.12). A ListedCourse
is an entry in a course catalog and is sponsored by a SchoolDistrict or some other education forum A ScheduledCourse is a specific offering of a ListedCourse and is delivered by a

Trang 4Teacher at a School using any number of Textbooks There is a CourseRegistration for each Student who participates in a ScheduledCourse Note that the Course archetype has two Item Description templates (see Chapter 5) ListedCourse corresponds to ItemDescription and ScheduledCourse corresponds to Item Similarly, ScheduledCourse corresponds to ItemDe-scription and CourseRegistration corresponds to Item.
10.7 Customer
A Customer is someone involved in the purchase of products (Figure 10.13, Figure 10.14)
Customer reifies the customer role for a TangibleActor (in this case a person or organization,

see Section 10.2) Customers are critically important to business and there is special data to collect for them, such as sales data, credit information, and discount schedules You could use softcoding (see Chapter 13) to capture customer data, but an alternative is to define a
dis-tinct Customer entity type as shown here.
