Release 3.2

Release 3.2 (October 2021)

Release 3.2 adds:

• Open Metadata Type changes
• Dependency Updates
• Bug Fixes

Details of these and other changes are in the sections that follow.

Description of Changes

Open Metadata Types

The following changes have been made to the open metadata types:

Description of Changes

Open Metadata Types

The following changes have been made to the open metadata types:

• New types for modeling data processing purposes.
  See new type descriptions in models 0485.

• The following types have been deprecated: BoundedSchemaType, BoundedSchemaElementType,
  ArraySchemaType and SetSchemaType.
  See description in model 0507.

• The ServerEndpoint relationship can now connect to any ITInfrastructure elements, not just SoftwareServers.
  See description in model 0040.

• The OperatingPlatform entity can now record the patch level of the operating system. There are also new types for describing
  the contents of an operating platform.
  See description in model 0030.

• There are now types for distinguishing between virtual machines and virtual containers as well as bare metal hardware.
  There are also new types for specific technologies such as HadoopCluster, KubernetesCluster and DockerContainer
  to provide concrete examples of different types of hosts using popular technologies.
  Finally the DeployedVirtualContainer relationship has been deprecated in favor of a more generic HostedHost relationship.
  See description in model 0035.

• There are new types for define a storage volume that has been attached to a host.
  See description in model 0036.

• A new subtype of software server for reusable business functions (such as microservices) has been added called ApplicationService.
  See description in model 0057.

Beta documentation site

We are in the process of moving our documentation across to a new site at https://odpi.github.io/egeria-docs/ . This is still work in progress so some material is currently missing, and some links will fail.

This site should offer improved usability including navigation & search.

Please continue to refer to the main documentation site for any missing content until this migration is complete.

Deprecation of docker-compose

The docker-compose environment for running our Coco Pharmaceuticals lab demo/tutorial is now deprecated. The configuration is still available, but will not
be further developed or tested, and will be removed in a future release.

Our Kubernetes Helm charts are now recommended to quickly setup the same lab
environment, and the documentation for these has been improved to cover
a Kubernetes introduction, and example based on 'microk8s' which are suited to
an end user desktop environment (and can also be run in enterprise/cloud environments)

Egeria Helm charts repository

The Helm charts are now being developed at https://github.com/odpi/egeria. Charts are now published as a proper Helm Repository, making installation easier. This move also keeps their lifecycle independent of our various code repositories, and issues/features should be opened on that repository.

Charts are now installable without cloning the git repository. Instead first add the repository:

helm repo add egeria https://odpi.github.io/egeria-charts

You can list charts with:

helm search repo egeria

And install with :

helm install lab egeria/odpi-egeria-lab

The documentation is temporarily available at https://odpi.github.io/egeria-charts/site/ but will move to our new cross-repository Egeria docs repository soon.

Coco Pharmaceuticals lab environment changes

The Egeria UI is not available by default in the labs environment & is not tested. This is because at this time we don't have suitable test data or notebook walkthroughs available. To avoid confusion this is now disabled by default. It can be renabled through a feature flag (at cli or in an override file) ie:

helm install --set egeria.egeria-ui=true lab egeria/odpi-egeria-lab

Note that the Egeria UI continues to be developed. This change is purely due to ensuring consistency of the demo/tutorial environment.

For browsing the type system and repository within this environment, use the React UI.

Known Issues

• It is recommended to use a chromium-based browser such as Google Chrome or Microsoft Edge, or alternatively Apple Safari for the Egeria React UI. Some parts of the UI experience such as Dino currently experience problems with Firefox. See odpi/egeria-react-ui#96 .

Release 3.0

Release 3.0 (August 2021)

Release 3.0 adds:

• Requirement to build & run with Java 11 (LTS) or above

Details of these and other changes are in the sections that follow.

Description of Changes

Java 11

As of Release 3.0 of Egeria, Java 11 is required to build and run Egeria.

Egeria will not build/run/be supported on Java 8. Developers are now able to use Java 11 only functionality.

Java releases beyond Java 11 up to the current release have some informal testing, and we do build verification on the current release (currently 16).

See Java for further information.

Release 2.11

Release 2.11 (July 2021)

Release 2.11 adds:

• New option to have multiple topics for a cohort.
• New support for automatic extraction of metadata from event brokers and API managers.

Details of these and other changes are in the sections that follow.

Description of Changes

New option to have multiple topics for a cohort

An open metadata repository cohort
uses three types of events to enable peer-to-peer sharing of metadata.
In previous releases, these events have all been exchanged through a single
event topic. Release 2.11 provides the option for a cohort to
use a dedicated topic for each type of event.
This improves the time to register a new member in the cohort
and allows multiple instances of a Metadata Server
or a Metadata Access Point
to access the cohort.

Details of these new options can be found in the
Administration Guide.

Extensions to the support for Data Managers

The Data Manager OMAS
has been extended to support the capture of metadata from
Event Brokers such as Apache Kafka and API Managers
such as an API Gateway.

There are two new associated
Open Metadata Integration Services (OMISs)
to support integration connectors
that extract metadata from these types of data managers:

• Topic Integrator OMIS
  supports integration connectors extracting metadata
  from Event Brokers.

• API Integrator OMIS
  supports integration connectors extracting API information from API managers.

For more information on the use of the Data Manager OMAS with
these integration services, see the
Data Manager Integration
solution.

Open Metadata Types

The following changes have been made to the open metadata types:

• Deprecation of properties in Asset

  A number of properties that where originally defined in Asset were moved to
  classifications to allow them to be managed independently of the original asset.
  This occurred before the TypeDefPatch support was in place and so these properties
  were not marked as deprecated at that time. In 2.11, this deprecation has now been
  officially recorded in the Asset TypeDef. The properties are:

  • owner - now captured in the Ownership classification
  • ownerType - also captured in the Ownership classification
  • zoneMembership - now captured in the AssetZoneMembership classification
  • latestChange - now captures]d in the LatestChange classification

  See new type description in model 0010.

• New types for APIManager and EventBroker.
  These types inherit from SoftwareServerCapability.
  These are used in the new Data Manager OMAS APIs.

  See new type descriptions in model 0050.

• New type for a Threat governance driver and a relationship to connect
  a GovernanceDefinition
  with a metadata element that defines the scope where it is applicable.

  See new type descriptions in models 0401 and
  0405.

• Deprecated type called TabularColumnType because it restricts tabular columns to primitive types when it could be a literal for example.
  Also a new subtype for TabularColumn called TabularFileColumn is added to be able to distinguish between tabular columns from
  files and RelationalColumn (which also inherits from TabularColumn).

  See type descriptions in model 0530.

• Deprecated types called SimpleDocumentType, StructDocumentType and MapDocumentType because they
  offer little value since the type is typically stored in the TypeEmbeddedAttribute classification.
  This change makes the document schemas consistent with other types of schema.

  See type descriptions in model 0531.

• Updated supertype of RelationalTableType to inherit from ComplexSchemaType rather than TabularColumnType
  since TabularColumnType is now deprecated.

  See type descriptions in model 0534.

• New type called EventTypeList to allow a list of event types to be associated with a topic
  and a specific subtype of SchemaAttribute
  for an attribute in an event type to make it easier to search for
  data fields that are exclusively found in events.

  See new type descriptions in model 0535.

• New types for APIParameter and APIParameter to allow the capture of properties
  related to the API's treatment of the parameters. There are also
  properties for APIOperation.

  See new type descriptions in model 0536.

• New types for DisplayDataSchemaType, DisplayDataContainer, DisplayDataField, QuerySchemaType,
  QueryDataContainer and QueryDataField to allow the capture of properties related to the display of data to end users.

  See new type descriptions in model 0537.

Bug fixes and other updates

• Additional Bug Fixes
• Dependency Updates

For details on both see the commit history in GitHub.

Removed Functionality

The following capabilities have now been removed (they were previously deprecated and/or in not in 'Released' status):

• Information View OMAS.
• Virtualization Services & associated connectors.
• Security Officer Services, Security sync services & associated connectors including for Apache Ranger.
• Gaian database connector & additional authentication/impersonation support.

Much of the above capability can be implemented via Integration Services .
Hadoop specifics may be developed in the future within the Egeria Hadoop GitHub repository.

For more details of this change see #5314.

Similarly, the following services have been deleted:

• Data Platform Services and Data Platform OMAS. For more details see #5344 .
• Data Platform capabilities are already available in Database Integrator and Files Integrator already part of Integration Services.
• Cassandra connectors: cassandra-data-store-connector and cassandra-metadata-extractor-connector will be introduced back
  in the Data Connectors GitHub repository. For more information see #2671 .

Known Issues

• It is recommended to use a chromium-based browser such as Google Chrome or Microsoft Edge, or Apple Safari for the Egeria React UI. Some parts of the UI experience such as Dino currently experience problems with Firefox. See odpi/egeria-react-ui#96 .

Special note on Java Support

• This is expected to be the last release supporting Java 8. The next release will commence the 3.x series of releases and require Java 11.

Release 2.10

Release 2.10 (June 2021)

Release 2.10 adds:

• New and improved open metadata types for governance
• New API for Governance Program OMAS

Details of these and other changes are in the sections that follow.

Note: Please review a copy of this content at https://egeria.odpi.org/release-notes/ to
access any embedded links correctly.

Description of Changes

Metadata Types

• Correction to the Campaign classification.

  The Campaign classification is supposed to connect to a Project entity to indicate the project
  is a grouping of a series of projects designed to achieve a large goal. Unfortunately it was coded to connect to
  the Collection entity. In 2.10, the Campaign classification has been changed to attach to Referenceable
  to allow it to be connected to Project without affecting backward compatibility.

  See new type description in model 0130.

• Extension of the UsedInContext relationship.

  The UsedInContext relationship linked two GlossaryTerm entities together to show that one glossary term described
  the context in which the other was valid. This relationship has been updated to allow the end that describes
  the context to be a Referenceable. This means that the context where glossary terms are valid can be expressed
  as elements such as projects, business capabilities, parts of an organization, subject areas, zones and many more.

  See new type description in model 0360.

• Allowing ownership to be expressed as a PersonRole.

  Issue #5104 described the problem that the
  governance open metadata types allowed owners to be expressed as PersonalProfile or UserIdentity
  entities.
  The properties did not identify if the owner was identified as a GUID or as a qualifiedName.
  In 2.10, a new classification for expressing ownership called, not surprisingly, Ownership,
  was introduced which allows and type and property name for the owner to be specified with the
  owner's identifier. The types for entities such as GovernanceActionType and IncidentReport that include
  ownership properties in them have been updated to deprecate these properties in favor of using
  the Ownership classification. The AssetOwnership classification is also deprecated.

  See new type description in model 0445.

• Update to Certification relationship.

  The Certification relationship supports the identification of the people involved in the certification of an element. 2.10 adds
  new attributes to specify the type and property names of the identifier used to identify these people.
  This is consistent with the new Ownership classification.

  See new type descriptions in model 0482.

• Update to License relationship.

  The License relationship supports the identification of the people involved in the licencing of an element. 2.10 adds
  new attributes to specify the type and property names of the identifier used to identify these people.
  This is consistent with the new Ownership classification.

  See new type descriptions in model 0481.

• Governance role updates.

  The GovernanceOfficer entity now inherits from GovernanceRole rather than PersonRole.
  This means it is just another governance role that can be linked with GovernanceResponsibility
  definitions. In addition there are new types for different types of owners. These are ComponentOwner
  and DataItemOwner.

  See new type descriptions in model 0445.

• Extend the GovernanceResponsibilityAssignment

  The GovernanceResponsibilityAssignment relationship identifies the responsibilities for a particular role.
  It used to link to a GovernanceRole and in 2.10, it has been updated to link to a PersonRole. This means
  that governance responsibilities can be added to any role, such as ProjectManager and CommunityMember,
  rather than just specialized governance roles.

  See new type descriptions in model 0445.

• Deprecating the domain attribute in various governance types.

  The domain attribute is typed by the GovernanceDomain enum. This provides a fixed list of governance domains.
  An extensible mechanism for expressing the governance domain was added in release 2.4 using the
  GovernanceDomainDescription entity and the domainIdentifier attribute.
  In this release, the use of domain is deprecated in GovernanceDefinition,
  GovernanceZone, SubjectAreaDefinition, GovernanceMetric, GovernanceRole and GovernanceOfficer.

  See new type descriptions in model 0401.

• Extensions to governance drivers.

  There are now new subtypes of the GovernanceDriver entity called RegulationArticle and
  BusinessImperative. It is also possible to link governance drivers using the new
  GovernanceDriverLink relationship.

  See new type descriptions in model 0405.

• Update to AssetOrigin classification.

  The AssetOrigin classification supports the identification of the origin of an asset. This can be in terms of the
  organization, business capability and other values. 2.10 adds new attributes to identify if the
  organization or business capability is identified by its GUID or qualifiedName.

  See new type descriptions in model 0440.

• Improve IncidentClassifiers.

  If is possible to define multiple sets of IncidentClassifier values that can be
  used on IncidentReport entities to help to group and prioritize them. The IncidentClassifier entity
  now inherits from Referencable and there is a new classification called IncidentClassifierSet
  to mark a Collection entity as containing IncidentClassifier definitions.

  See new type descriptions in model 0470.

• Deprecation of ResponsibilityStaffContact.

  The ResponsibilityStaffContact relationship has been deprecated in favor of the
  GovernanceResponsibilityAssignment relationship.

New Services for Governance Program OMAS

The APIs defined for Governance Program OMAS have been updated to reflect the changes
to the open metadata types described above. The APIs and client implementations
are in place. The server-side is coming in a future release.

Bug fixes and other updates

• Additional Bug Fixes

  • Cascaded deletes for entities grouped using the Anchors classification
    are now deleting the correct entities. Prior to this release, some entities were
    missed and others were deleted incorrectly.

• Dependency Updates

For details on both see the commit history in GitHub.

Known Issues

• It is recommended to use a chromium-based browser such as Google Chrome or Microsoft Edge, or Apple Safari for the Egeria React UI. Some parts of the UI experience such as Dino currently experience problems with Firefox. See odpi/egeria-react-ui#96 .
• When running the 'Understanding Platform Services' lab, ensure you run the 'egeria-service-config' notebook first and do not restart the python kernel before running this lab. See #4842 .
• The governance samples currently do not work. See See #5300 and See #5299 for more details
• When logging in to the react UI for the coco pharma lab demo, ensure to use http://myhost.mydomain/coco/login as otherwise the login will not work. see odpi/egeria#41
• A few further UI bugs are noted at #5211 (comment)

Release 2.9

Release 2.9 (May 2021)

Release 2.9 adds:

• Changes to metadata types
• Changes to building Egeria on Windows

Details of these and other changes are in the sections that follow.

Description of Changes

Metadata Types

• The UserProfileManager, UserAccessDirectory and MasterDataManager classification for Referenceables has been added
  to model 0056 Asset Managers.
• A new relationship called ActionTarget to link a To Do to the elements that need work has been added
  to model 0137 Actions for People.
• A new attribute called filterExpression has been added to the Port entity in
  model 0217 Ports.
• A new classification called PrimaryCategory has been added to
  model 0335 Primary Category.
• A new classification called GovernanceMeasurements has been added to
  model 0450 Governance Rollout.
• The RelationalColumnType entity in
  model 0534 Relational Schema.
  only allows for a column to be primitive. It could be a literal, enum or external and so this type has been deprecated
  and the appropriate schema types should be used directly.

Building Egeria on Windows

To build Egeria on Windows you should use Windows Subsystem for Linux Version 2 or above & install an
appropriate Linux distribution.

Egeria should then be built & run within this environment.

IDEs such as IntelliJ and VSCode support editing and code management within the Windows GUI alongside build and execution in Linux.

See PR #5084 for more information.

Bug fixes and other updates

• Additional Bug Fixes
• Dependency Updates

For details on both see the commit history in GitHub.

Known Issues

• It is recommended to use a chromium-based browser such as Google Chrome or Microsoft Edge, or Apple Safari for the Egeria React UI. Some parts of the UI experience such as Dino currently experience problems with Firefox. See odpi/egeria-react-ui#96 .
• When running the 'Understanding Platform Services' lab, ensure you run the 'egeria-service-config' notebook first and do not restart the python kernel before running this lab. See #4842 .

Release 2.8

Release 2.8 (April 2021)

Release 2.8 adds:

• New support for event and property filtering for the open metadata server security connector
• Changes to metadata types
• New performance workbench for the CTS (technical preview)
• New interface for retrieving the complete history of a single metadata instance
• Splitting of CTS results into multiple smaller files

Details of these and other changes are in the sections that follow.

Description of Changes

Updates to the Open Metadata Security Connector

Before this release, the repository services support 3 filtering points for managing events for the OMRS Cohort Topic.

• Should an event be sent to the cohort
• Should an event be retrieved from the cohort
• Should a received event be stored in the local repository

These filtering points are set up in the configuration document of the server.
It is possible to specify rules to determine which types of events and which types of metadata elements are filtered out.
However this configuration provides no control to allow filtering of events for specific instances.

This release extends the metadata server security connector so it can be called at these same filter points.
This will be through optional interfaces that the security connector can choose to implement.

If the current rules are set up, they will still be executed. This change complements the existing filtering.

The server security connector also implements the repository security interface called when metadata is being
added/updated/deleted/retrieved through the APIs. Extending the security connector for event filtering means that it can make consistent decisions on the sharing of metadata through the cohorts and through the APIs.

Configuring the server security connector

Configuring the server security connector will not change with this feature.
If the connector needs custom attributes to select rule sets etc, these can be specified in the configuration properties.

See https://egeria.odpi.org/open-metadata-implementation/admin-services/docs/user/configuring-the-server-security-connector.html.

Implementing the server security connector

The security server connector will have two new interfaces that it can implement: one for the cohort events and one for saving events to the local repository.

• The event interface will have two methods, one for sending and one for receiving. The parameters will include the cohort name and the event contents. It can return the event unchanged, return a modified event (eg with sensitive content removed) or return null to say that the event is filtered out.

• The event saving interface will receive the instance header and can return a boolean to indicate if the local repository should store it. If true is returned, the refresh event sequence is initiated. The repository connector then has the ultimate choice when the refreshed instance is returned from the home repository as to whether to store it or not.

There is a single instance of the connector in the server so it is able to maintain counts and cache rules etc. It can also be implemented as a facade to a proprietary service.

More information on the security connector can be found
on this page:

https://egeria.odpi.org/open-metadata-implementation/common-services/metadata-security/metadata-security-apis

Metadata Types

• Updates to the location types in model 0025:

  • Add the mapProjection property to the FixedLocation classification
  • Change the address property to networkAddress in the CyberLocation classification
  • Deprecated HostLocation in favor of the AssetLocation relationship

• Deprecate the RuntimeForProcess relationship since it is superfluous - use ServerAssetUse since
  Application is a SoftwareServerCapability.
  See model 0045.

• Replace the deployedImplementationType property with the businessCapabilityType in the BusinessCapability
  since it is a more descriptive name.
  See model 0440.

Performance workbench

The performance workbench intends to test the response time of all repository (metadata collection) methods for the
technology under test. The volume of the test can be easily configured to also test scalability.

More information is available in the workbench's documentation.

Instance history interface

Two new (optional) methods have been introduced to the metadata collection interface:

• getEntityDetailHistory
• getRelationshipHistory

Both methods take the GUID of the instance for which to retrieve history, an optional range of times between which to
retrieve the historical versions (or if both are null to retrieve all historical versions), and a set of paging
parameters.

If not implemented by a repository, these will simply throw FunctionNotSupported exceptions by default
to indicate that they are not implemented.

CTS results output

Up to this release, the detailed results of a CTS run could only be be retrieved by pulling a huge
(100's of MB) file across the REST interface for the CTS. Aside from not typically working with most REST clients
(like Postman), this had the additional impact of a sudden huge hit on the JVM heap to serialize such a large JSON
structure (immediately grabbing ~1GB of the heap).

While this old interface still exists for backwards compatibility, the new default interface provided in this release
allows users to pull down just an overall summary of the results separately from the full detailed results, and the
detailed results are now broken down into separate files by profile and test case: each of which can therefore be
retrieved individually.

(So, for example, if you see from the summary that only 1-2 profiles are not conformant, you can retrieve just the
details for those profiles rather than all details.)

Changes to deployment of the Polymer based UI

In previous releases, a zuul router component was used within the UI server chassis to route requests
for static content to a separate server.

In this release any routing needs to be setup externally, for example by placing a nginx proxy in front of both the ui
chassis and static content server. This is now done by our docker-compose environment & helm charts so to access
the UI you need to go to the nginx proxy. Further summary information can be found in the documentation for those assets.

Bug fixes and other updates

• Additional Bug Fixes
• Dependency Updates

For details on both see the commit history in GitHub.

Known Issues

• It is recommended to use a chromium-based browser such as Google Chrome or Microsoft Edge, or Apple Safari for the Egeria React UI. Some parts of the UI experience such as Dino currently experience problems with Firefox. See odpi/egeria-react-ui#96 .
• Egeria source code currently fails to build on Windows natively. Please use Linux, MacOS, or compile under WSL/WSL2 on Windows. See #4917
• Several Java samples fail (governance, admin) - #4656, #4662, #4056
• The React UI used by the helm charts and compose is based on react UI release 2.7.0 due to layout issues found with 2.8.0. See #5022
• The platform services notebook may fail to query servers correctly. See #5023
• The building a data catalog notebook may fail if run quickly. See #2688
• The data curation notebook is incomplete and still being developed. The final steps may fail to work in a container environment. See #5021

Release 2.7

Release 2.7 (March 2021)

Release 2.7 adds:

• Performance improvements in the graph repo
• Changes to metadata types
• Changes to the distribution process

Details of these and other changes are in the sections that follow.

Description of Changes

Build & Release changes

• Previously release maven artifacts have been pushed to JCenter (in addition to Maven Central), and snapshots have been pushed to odpi.jfrog.io/odpi/egeria-snapshot. As of 2.7 this no longer occurs and release and snapshots are pushed only to Maven Central.
• Due to the above, maven artifacts may be signed by a different user to previously (and this may change in a future release).

Performance Improvements

• Release 2.7 includes performance improvements to the graph repository's search methods, which select an efficient query strategy based on the properties and type filters supplied to the search.

Metadata Types

• We have removed overloaded properties that existed at multiple levels in a type definition: for example, length was defined both on SchemaAttribute and again on RelationalColumn (which is a subtype of SchemaAttribute). This change removes them from being defined again the lower level (RelationalColumn in this example); however, the property itself will still be available at the lower level due to inheriting it from the supertype.

Bug fixes and other updates

• Additional Bug Fixes
• Dependency Updates

For details on both see the commit history in GitHub.

Known Issues

• It is recommended to use a chromium-based browser such as Google Chrome or Microsoft Edge, or Apple Safari for the Egeria React UI. Some parts of the UI experience such as Dino currently experience problems with Firefox. See odpi/egeria-react-ui#96 .
• When running the 'Understanding Platform Services' lab, ensure you run the 'egeria-service-config' notebook first and do not restart the python kernel before running this lab. See #4842 .

Release 2.5

Release 2.5 ( November 2020)

Below are the highlights of the 2.5 release:

• The following improvements to the presentation-server user interface:

  • The Type Explorer UI

    • supports options to show/hide deprecated types and/or deprecated attributes. Please refer to the Type Explorer help.md for details.
    • preserves the user-selected focus type across reloads of type information from the repository server.

  • The Repository Explorer UI

    • has the Enterprise option enabled by default. It can be disabled to perform more specific, localized queries.
    • now indicates whether an instance was returned by an enterprise or local scope operation against its home repository or is a reference copy or proxy.
    • has a user-settable limit on the number of search results (and a warning to the user if it is exceeded)
    • now colors nodes based on their home metadata collection's ID. This previously used metadata collection's name but a metadata collection's name can be changed, whereas the metadata collection's ID is permanent.
    • has improved help information covering search

  • The Dino UI

    • displays a server's status history in a separate dialog instead of inline in the server details view.

• The following improvements to the repositories:

  • The Graph Repository

    • find methods have reinstated support for core properties, previously temporarily disabled due to property name clashes that are now resolved

• A new type 'OpenMetadataRoot' has been added as the root type for all Open Metadata Types. See the base model

• The admin services guide has some additional information on configuring TLS security

• Improvements to the gradle build scripts, but at this point it remains incomplete and build of egeria still requires maven

• Bug Fixes

• Dependency Updates
