Dojo Details:

This is a hands on session on Metadata Governance using Egeria for Governance team, who are interested in implanting mature information governance practises across the information landscape using Egeria, 

If you are familiar with Egeria – you will know that it provides an open set of types to describe you information landscape, allowing you to easily integrate information sources by mapping to a open common way of communicating.

Now you have described your world in metadata, means you have an information picture or your landscape in metadata. This view is across vendors, across technologies and across domains. 

This dojo will show you how an organisation can govern coherently across this landscape. 

The Dojo will cover the following aspects of governance:

Metadata Supply

An Information Supply Chain identifies the flow of a particular type of data across a digital landscape. It is an architectural construct that can provide the focus for data governance activities that ensure data is delivered where it is needed in a timely and efficient manner.


Lineage shows how data flows from its origins to its various destinations. This includes details of processing along the way.


  • Understand not just what was is stored in the metadata now, but what was known at a particular moment in time.
  • Define when a particular element is effective (i.e. visible and active) and when it ceases to be effective.


Duplicate management identifies multiple metadata instances that represent the same concept or resource. 

Metadata Discovery

An automated process that extracts metadata about a digital resource. This metadata may be:

  • embedded within the asset (for example a digital photograph has embedded metadata), or
  • managed by the platform that is hosting the asset (for example, a relational database platform maintains schema information about the data store in its databases), or
  • determined by analysing the content of the asset (for example a quality tool may analyse the data content to determine the types and range of values it contains and, maybe from that analysis, determine a quality score for the data).

Governance Actions

Governance action describes some processing that is part of the governance of an organization’s asset or the metadata that describes them.

Governance Maturity

There are five levels of maturity that build on one another until the organization is able to support a wide range of advanced resource and data use along with appropriate self-service access to data for a majority of people in the organization.
