Matching Data to Schema Elements
The data you identified in your site survey now needs to be mapped to the existing
directory schema. This process involves the following steps:
•
Identify the type of object the data describes.
Select an object that best matches the data described in your site survey.
Sometimes, a piece of data can describe multiple objects. You need to
determine if the difference needs to be noted in your directory schema. For
example, a telephone number can describe an employee's telephone number
and a conference room's telephone number. It is up to you to determine if these
different sorts of data need to be considered different object in your directory
schema.
•
Select a similar object class from the default schema.
It is best to use the common object classes, such as groups, people, and
organizations.
•
Select a similar attribute from the matching object class.
Select an attribute from within the matching object class that best matches the
piece of data you identified in your site survey.
•
Identify the unmatched data from your site survey.
If there are some pieces of data that do not match the object classes and
attributes defined by the default directory schema, you will need to customize
the schema. See "Customizing the Schema," on page 46 for more information.
For example, the following table maps directory schema elements to the data
identified during the site survey in Chapter 2:
