Short description/
Transmitted information
  • Open Services for Lifecycle Collaboration (OSLC) is a set of specifications that enable integration of software development. It has evolved, and continues to evolve, to areas such as Application Lifecycle Management (ALM), Product lifecycle Management (PLM), IT Operations and more.

Positioning of OSLC in V-Model


  • Reasons for promoting standardization:
    • Enable openness and interoperability for engineering tools
    • Enable cooperation across engineering departments and disciplines
    • Enable traceability throughout the entire life cycle
    • Avoid vendor lock-in
    • Promote data consistency
    • Enable Reusability of existing OSLC REST APIs
  • Based on W3C standards (Linked Data Platform, XML/RDF, HTTP)
  • Inspired by Semantic Web


  • June 2013: Creation of the OASIS-OSLC member section
  • Nov. 2013: Start to transfer the first OSLC community results to OASIS-OSLC

  • Okt. 2020: OSLC Core v3.0 OSLC Query v3.0 OLSC Requirements Management v2.1 and OSLC Change Management v3.0 published

Relevance and Benefit for MBSE

  • The OSLC Core Specification is a Hypermedia API standard mainly adopted in software and systems engineering domains, but with the potential to provide value to any domain with data integration challenges. The OSLC Core specifications expands on the W3C LDP capabilities, to define the essential and common technical elements of OSLC domain specifications and offers guidance on common concerns for creating, updating, retrieving, and linking to lifecycle resources.
  • OSLC is not the only way to build a linked architecture but it reduces implementation effort as far as specifications exist.

Risks and Impediments

  • Main Focus on Software and System Development
  • Federated Architecture can be supported by other Technologies (Graph DB)
  • Obstacle for implementation is the missing methodology and experiance for interdisciplinary collaboration
