Publication for Capella provides a seamlessly integrated view of your system architecture to authorized stakeholders.

You can publish Capella models on a web server, and connect them with third-party repositories using traceability links to requirements, change requests, test cases, releases, and more.

The supported repositories include Siemens Polarion® and IBM Jazz.

Keep models and requirements in-synch

Digital thread from
requirements to architecture

Avoid errors by efficiently maintaining consistency and alignment between Capella models and artifacts managed in third-party repositories (like ALMs).

Drag&drop requirements into Capella

Better communication
and collaboration

Break silos between teams by providing online access to system architecture and facilitating engineering teams to reuse work items and system elements.

Drag&drop requirements into Capella

sources of truth

Author system design and work items with dedicated but connected tools and make this data available across different engineering disciplines.

Collaboration on an Integrated View


Drag&drop requirements into Capella


Define an integrated system architecture federated with third-party repositories, and decide when to expose this consistent content to other stakeholders.

Drag&drop requirements into Capella


Create requirements, issues, test cases, etc, in third-party repositories, and collaborate with systems engineers to align these artifacts with the system architecture.

Integrated View

Benefit from an integrated and consistent view of the system architecture: a detailed model with verified traceability relationships to related engineering artifacts.

Keep models and requirements in-synch


Control how the Capella models are exposed to stakeholders, and how they can be integrated with various third-party repositories containing engineering artifacts.

Systems Engineer

From the Capella Workbench

  • Publish Capella models on the Publication server.
  • Manage traceability links between Capella model elements and artifacts defined in connected repositories.

 Other Engineers

From a Third-Party Repository connected to the Publication server

  • Manage traceability links between artifacts defined in a connected repository and Capella model elements.

Integrated View Consumer

From a Web Browser

  • Find an element in a published Capella model.
  • Browse its properties, relations and diagrams.
  • View its traceability links and related artifacts.

Project Lead

From the Publication Server

  • Configure the type of links between the Capella model elements of a project and third-party artifacts.
  • Connect third-party repositories to the Publication server.
  • Manage authorized users on a per-project basis.

Integration using standard APIs

Third-party repositories such as Application Lifecycle Management Systems (ALM) and Requirements Management Systems (RMS) allow you to efficiently capture, organize, and link artifacts: requirements, tasks, issues, change requests, test cases, releases, etc. Rather than spreadsheets, using such tools is the best solution to efficiently manage your projects.

To enable traceability with objects managed in other repositories, some ALM and RMS tools support OSLC (Open Services for Lifecycle Collaboration), a set of specifications for APIs to interact with data on the web: searching, visualizing, and analyzing.

OSLC (Architecture Management) is an OSLC specification for exposing fine-grained architectural data to external systems via a modern Linked Data approach: no import/export between tools, resources are connected together to create a virtual continuity between repositories and to make it easier for tools to work together in different areas. 

By supporting this specification, Publication for Capella enables the traceability between any system element in Capella and any artifact in OSLC-compliant tools.
