Receive notification messages for changes on your Twins

Get notified about what is going on in your Digital Twin Registry. You can now receive messages for changes to your Twins. Be informed when Twins or aspects have been created, retrieved, updated, or deleted.

  • Look up the notifications via your web browser — directly in the Digital Twin Registry web app.

  • Consume the Kafka notification messages, for example, by a Spring Boot consumer.

To enable this feature for your tenant, send an email to support.semantic-stack@bosch.com.

Read more: Send Notification Messages for state changes.

Give write access only to selected users of your Asset Administration Shells

Distinguish between users who can only retrieve your Asset Administration Shells and users who can create, update, or delete shells. You can now selectively grant read or write access to your users by assigning one of the dedicated roles:

  • AAS Viewer for read access

  • AAS Manager for write access

Keep local identifiers confidential through Business Partner Numbers (BPN)

You can now provide your business partners with individual Business Partner Numbers (BPN).

With such a BPN being a mandatory part of API calls to the Digital Twin Registry, your business partners will not see any of the local identifiers of your assets when consuming your assets' data. This way, you can ensure that third parties get the data they need while you will not reveal internal IDs, for example, part numbers, to your business partners.

New API version with increased performance due to cursor-based paging

Out now: the Digital Twin Registry API v2externallink 20.

We have improved the performance of the Digital Twin Registry API by moving to cursor-based paging. This enables the Digital Twin Registry API to efficiently serve data even for very large data sets.

Read more: Find Twins in the Digital Twin Registry > Paging.

Breaking change announcement: The Digital Twin Registry API v1 will be deprecated by September 30, 2023. Please migrate your API calls to Digital Twin Registry API v2 in a timely manner.

SAMM Aspect Models supported

The Digital Twin Registry now also accepts SAMM Aspect Models.

Currently, you can work with both BAMM and SAMM Aspect Models. This is due to the transition of the open-source specification for Aspect Models — from BAMM Aspect Meta Model to the Semantic Aspect Meta Model (SAMM), with a new home at the Eclipse Semantic Modeling Framework.

Breaking change announcement: The Digital Twin Registry will only support SAMM Aspect Models by September 30, 2023. Please migrate any legacy BAMM Aspect Models to SAMM Aspect Models in a timely manner.

Use SAMM Aspect Models

Following the recent release of the Semantic Aspect Meta Model (SAMM)externallink 20, you can now work with Aspect Models based on SAMM.

Legacy Aspect Models based on the BAMM Aspect Meta Model are not supported anymore by the Aspect Model Catalog.

View the available namespaces for your tenant

You can now look up the namespaces that have been activated for your tenant.

Read more: Namespaces > The namespaces on your tenant.

Manage the release state of your namespaces

Completing the namespace management feature, you can now transition your namespaces from draft, to released, to deprecated.

Note that your Aspect Models — as they are organized under namespaces — get the same release state as the namespace they belong to.

Read more: Namespace state management.

Delete DRAFT namespaces

A namespace that is still in the DRAFT release state can now be deleted from the Aspect Model Catalog.

Note that RELEASED namespaces can only be DEPRECATED but not deleted. This helps to prevent breaking changes for users who employ Aspect Models of an already RELEASED namespace.

Read more: Namespace state management > Delete a namespace.

2023.R2 (DTR + AMC)

At a glance:

When using the Digital Twin Registry to expose data for your business partners, you want your organization’s legal notice, data protection notice, etc., to be provided. The same is true when working together on Aspect Models with the Aspect Model Catalog.

You can now add your organization’s legal texts to the Digital Twin Registry and the Aspect Model Catalog. Your legal information gets displayed in the footer area of the graphical user interface in the web applications.

Now generally available — Bosch Semantic Stack with the Digital Twin Registry!

Digital Twin Registry

DTR-7.1.0

Feature overview:

  • Manage Twins

    • Register, merge, delete, and look up Twins for your assets.

    • Typically, a Twin represents your assets, for example, machines, vehicles, or generally any product instances or product types.

  • Manage local identifiers

    • Add local identifiers to your twins.

    • By that, each twin can be found by searching for such local identifiers like vehicle identification numbers (VIN) or serial numbers etc.

  • Manage aspects

    • Each Twin can carry various aspects, pointing to the implemented aspect API which provides data for your Twin.

    • By adding aspects iteratively, you can start small while your Twins can grow and provide more and more data over time.

  • Add or delete aspect endpoints

  • Bundle your Twins in groups

    • With Digital Twin Groups, you can organize a set of Twins into one entity.

    • A Twin can be part of several Digital Twin Groups.

    • Easy operations or management for large sets of Twins.

    • Read more: Digital Twin Groups.

  • Work with templates

    • Aspect templates are an abstraction over aspects sharing common features among multiple Twins.

    • Instances of aspect templates are called virtual aspects.

    • With endpoint templates, virtual aspects are rendered at runtime as if they were concrete aspects.

    • Aspect templates are created in association with Digital Twin Groups.

    • Read more: Aspect templates.
