Egeria Road Map and Destination

Egeria is a large project with many different activities adding content to the project. This page provides an overview of the aims of the project and a reflection of where we are today.

Figure 1 shows the five layers of capability that Egeria is aiming for.

Understanding the road map

Figure 3 shows an overview of the status of the functions in Egeria today. Green means that there is function that is either released or technical preview. Orange means there is work going on and red means it is planned but not started.

This chart is being updated with each release.

As you can see, some progress has been made on all layers. However, since they do build on one another, most of the early work has been focused on establishing the frameworks, connector APIs and other services to provide the developer platform. The developer platform provides the libraries and interfaces to build connectors to integrate third party tools along with the runtime to host these connectors and manage the metadata exchange.

Today we have a robust platform called the OMAG Server Platform and the ability to configure OMAG Servers that host specific types of connectors to third party tools. The initial focus was to enable third party metadata servers to connect together in the peer-to-peer open metadata repository cohort. This capability is delivered along with two repository connectors for the following third party connectors:

Through 2020, our focus has shifted to the integration platform as we add connector implementations for popular third party technologies and standards and build out the integration user interface (UI) that will enable an organization to:

The integration UI makes calls to specialized REST services supported by a type of OMAG Server called the View Server. The view server is new for 2020 and enables the REST APIs to the UIs to be deployed in a DMZ and the metadata servers to be behind an additional firewall. It also takes much of the load for supporting end users off of the metadata servers.

In 2020 there is also support for a new type of OMAG Server called the Integration Daemon. This server supports integration services that can host integration connectors dedicated to exchanging metadata with specific third party technologies.

The support for the governance solutions naturally follows along, building on the two lower levels. The governance solutions themselves complement specific metadata and governance solutions available in the market today. Egeria is focused on filling in the gaps to support individuals that are setting up and running an open metadata ecosystem and wish to take advantage of the enterprise perspective it beings.

The first solution is Historical Lineage Exploration. This is approaching its first tech preview release around third quarter 2020. This provides a user interface for finding assets and viewing their lineage along with a dedicated governance server called the Open Lineage Server.

Next will be the Subject Area Management solution closely followed by the others in 2021.
