Introduction

Each Core Identity can have zero to N employments, whereas an employment is the combination of an organizational unit assignment, an optional function, an optional employment type, a validity range and optional attributes.

Properties

Whenever you are creating or updating an employment, you have to specify the following properties:

Main Employment

If a person has more than one employment, there is often a need to determinate its main employment. This can be used in many places such as mappings. For example a Core Identity can have two employments but you would like to provision its job title to a target system. In order to determinate the job title, the main employment is used.

The rules to choose the main employment are as following:

Only consider employments, which are not in state “deleted”, then:

• Main Employment is set

• Order by

  • Valid From and not expired

  • Percentage

  • Has valid to

  • Valid to

  • Id

The actual implementation might clear up any remaining questions:

return employments
    .Where(a => a.EmploymentState.Id != (uint)CoreIdentityEmploymentStates.Deleted)
    .OrderByDescending(a => a.EmploymentState.Id)
    .ThenByDescending(a => a.MainEmployment)
    .ThenByDescending(a => a.ValidFrom <= DateTime.Now && (!a.ValidTo.HasValue || a.ValidTo.Value >= DateTime.Now.Date))
    .ThenByDescending(a => a.Percentage)
    .ThenBy(a => a.ValidFrom)
    .ThenBy(a => a.ValidTo.HasValue)
    .ThenBy(a => a.ValidTo)
    .ThenBy(a => a.Id);
