Open Source

Value-added collaboration between companies

Optimal added value and the highest level of customer satisfaction cannot be generated alone. Especially in the automotive sector and for manufacturers of industrial components, the usually complex products are the result of an interplay between different companies or suppliers. By using these existing synergies even more broadly, the full potential of semantic data homogenization can unfold. The basis is an open ecosystem with jointly developed open source approaches.

Committees and associations to promote an open ecosystem

Committees and associations around the world are working to maximize synergies and are actively contributing to the open ecosystem. Thanks to the heterogeneity of the participants, specific industry, manufacturing and IT knowledge flows into the development of open source approaches. Together, the defined goals can be achieved faster and more efficiently. Bosch is involved in the leading initiatives on the topic of data homogenization and semantics.

Catena-X

The Catena-X Automotive Network aims to create an open ecosystem for the efficient and secure exchange of information between companies in the automotive industry. The focus is on benefits and added value for all participants in the network while maintaining data sovereignty and data security in accordance with European values and legal requirements (Gaia-X). Bosch is a member of the Catena-X Automotive Network e.V. and is also actively involved in the publicly funded Catena-X development project.

IDTA

The Industrial Digital Twin Association (IDTA) is the central point of contact for digital twin technology in industry – an alliance of active developers working together to make the digital twin usable for industry through open technologies. IDTA's main project is the Asset Administration Shell (ASS), as the go-to standard for implementing digital twins in Industry 4.0 systems. Bosch is an active member of the board and heads the "Open Technology" working group.

Eclipse Foundation

The Eclipse Foundation aims to strengthen collaboration and innovation in open source software by providing an optimal working environment. Bosch is a "Strategic Member" and part of the working group "Eclipse Semantic Modeling Framework (ESMF)”, a sub-project of the IDTA's overarching project "Eclipse Digital Twin". This top-level project drives the development of reference implementations for the activities of the Industrial Digital Twin Association (IDTA).

The purpose of the ESMF is the development of the Semantic Aspect Meta Model (SAMM) and the modeling and development tools to create and use Aspect Models. Bosch is also contributing to Eclipse Tractus-X™ project, the official open-source project in the Catena-X ecosystem under the umbrella of the Eclipse Foundation.

COVESA

This open, collaborative technology alliance is driving the full potential of connected vehicles. Members of COVESA are automotive manufacturers, Tier1 suppliers, and technology companies. Bosch is actively participating in the development and extension of VSS and the VSS ontology to create a common understanding of vehicle signals across the automotive industry for data-driven mobility services.

Open source tools and standardized specifications

The open source tools and specifications developed in numerous initiatives to promote open industry standards are part of Bosch Semantic Stack. At the same time, they are freely usable by all companies that want to drive data homogenization. Non-invasive, low-threshold, and incorporating native IT infrastructure, they also enable small and medium-sized companies to fully participate in digitalization in the automotive sector and in the manufacturing of industrial components.

Aspect Model Editor – low-threshold entry into the SAMM world

The Aspect Model Editor is a graphical no-code editor that enables the intuitive creation of aspect models – and at the same time helps to understand this abstract construct and to use it comprehensively and across companies. With the help of predefined creation rules, selection options and validation of individual work steps, the Aspect Model Editor coaches users through the process. It teaches the Semantic Aspect Meta Model and its underlying semantic concepts step-by-step in a "learning by doing" style.

SAMM-CLI and Software Development Kits – programming interfaces easily

The variety of programming environments used within the open ecosystem makes interface programming necessary. This is where the SAMM Command Line (SAMM CLI) comes into play; a command line interface that makes the development flow between different applications easier and more efficient by automatically generating or validating artifacts. Within the Eclipse Foundation, user-friendly software development kits specifically for Java, JavaScript and Python enable a vibrant community around the SAMM Aspect Meta Model.

Semantic Aspect Meta Model – a global and open specification

To be understood and reused beyond their own organization, aspect models must all have the same specification. This is achieved by using the open and standardized Semantic Aspect Meta Model (SAMM). A meta model specifies globally how aspect models must be defined together with their structure, properties, and relations – a semantic basic recipe, so to speak, according to which every aspect model must be designed to be (machine) readable.

Asset Administration Shell - interoperability for digital twins

The Asset Administration Shell (AAS) has emerged as the manufacturer-independent standard for the implementation of digital twins in Industry 4.0 systems and ensuring seamless interoperability. The AAS enables the cross-manufacturer exchange of information and uses industry-neutral standards. Bosch Semantic Stack provides a portfolio of tools with which ASS-compliant digital twins can be created and managed. All specifications defined by the IDTA for the ASS are automatically fulfilled.
