Attribute

A category of information to which a value will be assigned. The category is the general information, while the value is the more specific information.

Example

1. An attribute called Manufacturer is configured, and

2. When the object is created, the value of the attribute Manufacturer is specified as General Electric.

Data Item

A data item is an item in the class template that contains a point definition. A data item becomes a CIMPLICITY point when the class is instantiated into an object.

Instantiation

Producing a particular object from its point class template. This involves allocation of a structure with the types specified by the template and initialization of attributes with either default values or those provided by the user.

Just-in-Time Data Item

Just-in-Time (JIT) data items are not written to the point database when an object is instantiated; rather, the point configuration is created on demand. JIT data items are exclusive to classes.
