Blue - Intermediate sessions

Calling the metadata server API

In this session, you will learn some of the API calls that are possible on the metadata server.

Calling API Content

For this exercise, you will be using the following Postman collections: * Egeria-repository-services-local-repository * Egeria-asset-owner-omas

The aim is to show the differences between the fine-grained repository services APIs and the courser-grained, but more specialized access services APIs.

Design philosophy

Start with the the Asset Owner OMAS interface and add a CSV file. This returns a list of assets it has created, one for the directory and one for the filename. Retrieve these assets using the

Now use the repository service API to see how these assets are stored.

What are the differences?

Later on today, you will have a change to work with the Open Metadata Labs that provide a lot more explanation on the APIs and their differences. The purpose of this exercise was to giver you direct experience of the REST APIs.
