Legend

Each cell in the tables above indicated location-specific support for each attribute in terms of supported populations and currency of the information. The following codes are used to indicate this.

The supported population is described by one-letter codes that indicate the supported eduPerson affiliation:
- Faculty
- Student
- STaff
- ALum
- Member
- Affiliate
- Employee
- Library-walk-in
- An X indicates support for all affiliations.
The currency of the information is described by a code that indicates the number of Hours, Days, Weeks, or Months that the information may be out of date. For example, "10H" indicates ten seconds, and "2M" indicates two months. N indicates that there is no currency standard for this attribute (e.g., it is managed by the user).
If further explanation is needed, an asterisk ("*") is linked to a separate page that is named after the campus.
Examples:
- An attribute that is always up to date for all users: X
- An attribute that is made current for employees once a week, but has no currency standard for other affiliations. There are some exceptions that need explanation, however: FTE 1W *
