2.11 (July 2021)¶
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 will require Java 11.
Known issue: use chromium-based browser for UIs
It is recommended to use a chromium-based browser such as Google Chrome, 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 .
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 access server to access the cohort.
Details of these new options can be found in the administration guide.
Data Manager OMAS extension to support capture of event metadata
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.
Information View OMAS, Virtualization Services, Security Officer Services, Gaian connector
The following capabilities have now been removed (they were previously deprecated and/or in not in 'Released' status):
- Information View OMAS
- Virtualization Services and associated connectors
- Security Officer Services, Security sync services and associated connectors including for Apache Ranger
- Gaian database connector and additional authentication/impersonation support
For more details of this change see #5314.
Data Platform Services, Data Platform OMAS, and Cassandra connectors
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 .
Type changes: added, modified, deprecated
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.
And a relationship to connect a GovernanceDefinition with a metadata element that defines the scope where it is applicable.
A new subtype for
TabularFileColumn is added to be able to distinguish between tabular columns from
RelationalColumn (which also inherits from
See type descriptions in model 0530.
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 to allow the capture of properties
related to the API's treatment of the parameters. There are also
See new type descriptions in model 0536.
Types for display of data to end users
New types for
QueryDataField to allow the capture of properties related to the display of data to end users.
See new type descriptions in model 0537.
Updated supertype of
RelationalTableType to inherit from
ComplexSchemaType rather than
TabularColumnType is now deprecated.
See type descriptions in model 0534.
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.
Deprecated type called
TabularColumnType because it restricts tabular columns to primitive types when it
could be a literal for example.
See type descriptions in model 0530.
SimpleDocumentType, StructDocumentType, MapDocumentType
Deprecated types called
MapDocumentType because they
offer little value since the type is typically stored in the
This change makes the document schemas consistent with other types of schema.
See type descriptions in model 0531.
TermISATypeOFRelationship because the ends are defined the wrong way round. When visualizing
end1 should point to end2. This relationship incorrectly has the super type pointing to the subtype. Use the new
IsATypeOfRelationship instead to represent an is-a-type-of relationship between two spine objects.
See new type descriptions in model 0380.
