Ensuring consistency between different baselines of models can be a challenge

Data exchange is a manual process with some drawbacks Employment of

different product structures, e.g. items “as specified” vs. “as built”

Redundancy by having the same data in different tools

Space System Data Repository

ECSS-E-TM-10-23 is an emerging European Standard facilitating the alignment of tools for improved data sharing

Open Services for Lifecycle Collaboration (OSLC) is an emerging technology for controlled information exchange


OSLC announced: OSLC became an open-source project

OSLC became part of the OASIS Open Standards Network

Many new Working Groups get started

OSLC Architecture matures: More and more specifications will be released

Eclipse Lyo project created: Provides tutorials as well as projects to ease OSLC-Adapter creation

IBM in-house development: Searching for a way to integrate all their frameworks building on the experience of the Web

25.03.2015

OSLC enables linking of data to gain information that can facilitate applying of knowledge

Enables integration at data level via links between related resources • Originally IBM initiative for tool integration • Inspired by the World Wide Web • OSLC is part of OASIS • Resources are defined in terms of W3C Resource Description Framework
