1. New [`osdu:wks:master-data--UserProfile:1.0.0`](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/E-R/master-data/UserProfile.1.0.0.md)
taking the
existing [AbstractContact](./abstract/AbstractContact.1.1.0.md) further, enabling standalone records, which can
to include `EffectiveDate` and `TerminationDate` like all the other master-data entities participating
in [AbstractGeoContext](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/E-R/abstract/AbstractGeoContext.1.0.0.md).
3. New [`osdu:wks:dataset--PhysicalMedia:1.0.0`](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/E-R/dataset/PhysicalMedia.1.0.0.md)
representing content, which is not (yet) available in digital form. Intended to be used as placeholders for
on-demand retrieval from StorageFacility. More details in
the [Schema Usage Guide](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/Guides/Chapters/02-GroupType.md#233-physical-media).
2.**Seismic Domain**<br>
The [dataset--FileCollection.SEGY:1.2.0](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/E-R/dataset/FileCollection.SEGY.1.2.0.md)
has been updated to include the [AbstractVectorHeaderMapping:1.1.0](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/E-R/abstract/AbstractVectorHeaderMapping.1.1.0.md)
containing header value override instructions. An additional Boolean flag Is3D has been added to ease the parser's
decision, which header locations to inspect. A relationship to StorageFacility allows references to physical storage
of e.g. tapes and their tape and box labels. All changes
are [summarised in the migration guide](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/Guides/MigrationGuides/M20/dataset--FileCollection.SEGY.1.1.0.md)
3.**Well Delivery Domain**
1. The [`osdu:wks:master-data--PlannedCementJob:1.2.0`](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/E-R/master-data/PlannedCementJob.1.2.0.md)
has been added with populated reference values for well-known schemes. New schema versions now refer to ChronoStratigraphicScheme for
2.[`osdu:wks:reference-data--ChronoStratigraphy:1.1.0`](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/E-R/reference-data/ChronoStratigraphy.1.1.0.md), and
is extended with definitions how attribute values are to be replaced during successful matches.
The [example reference values](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/ReferenceValues/Manifests/reference-data/LOCAL/ParentMatchingRuleSets.1.1.0.json)
are updated.
2.[AliasNameType](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/Guides/MigrationGuides/M20/reference-data--AliasNameType.1.0.0.md) was extended by an External
Data Services specific value `EDSConnectedSourceIdentifier`.
2. A new value set for [`ResourceLifecycleStatus`](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/E-R/reference-data/ResourceLifecycleStatus.1.0.0.md) with
recommended usage described in
the [Schema Usage Guide](https://community.opengroup.org/osdu/data/data-definitions/-/blob/v0.23.0/Guides/Chapters/06-LifecycleProperties.md#62-abstract-common-resources).
