Guidance on Metadata Life Cycle Management

Date of publication: January 10, 2024

Preamble

This guidance provides advice on how departmental officials can effectively manage metadata consistent with the information and data life cycle in respect of the following:

1. Metadata and the information life cycle

Like other types of information and data, it is important that metadata is actively managed to ensure its ongoing relevance, usefulness and links to the information and data it describes. The information life cycle can be used as the basis for outlining metadata life cycle management activities. This guidance offers an approach to managing metadata throughout the phases of its own life cycle that is based on the information life cycle.

2. Metadata life cycle management

The objective of metadata life cycle management is to optimize understanding of information and data, maximize its appropriate use and reuse, and reduce departmental time and effort in managing, locating and understanding information and data holdings. The table below describes activities, expected outcomes and relevant stakeholders that may be associated with each phase of the metadata life cycle. Departmental officials can use this approach to develop processes, procedures, and training to ensure that metadata life cycle management activities are effectively controlled and executed to meet business requirements. A metadata needs assessment (see Guidance on Assessing Metadata Needs) can further aid departmental officials in prioritizing metadata management activities and in focusing effort and energy on those activities that yield the greatest benefit to the department, the Government of Canada and Canadians.
