linkeddate

Linkeddate is a term used in data-management contexts to describe a date value that is linked to one or more other dates or date-related resources. The linkage is intended to ensure consistency across related records and to enable automatic recalculation when source dates change.

In relational databases, a linkeddate can be implemented as a computed column, a trigger-based update, or a foreign-key-linked date field whose value derives from another row’s date. In spreadsheet environments, it appears as a date cell that references other date cells through formulas, so changes propagate automatically. In software applications, linkeddate may be used to reflect dependent schedules, where a date on one record drives or constrains dates on related records.

In semantic web or linked-data contexts, a date associated with a resource may be expressed with a date property connected to other resources via URIs, using properties from standards such as Dublin Core or Schema.org. In project management or scheduling tools, linkeddate commonly represents a dependent date, such as an end date computed from a start date and a duration, or a milestone date that depends on the completion of preceding tasks.

Advantages of linkeddate include improved data consistency and easier tracking of dependencies. Limitations include added system complexity, potential performance costs, and the need for clear ownership of source dates. Since linkeddate is not a formal standard, implementations vary by platform and use case.
