OSLC Training

2-Day Workshop - Data integration using the next Web (Linked Data, OSLC)

This course provides an introduction to Linked Data and Open Services for Lifecycle Collaboration (OSLC) for developing the future generation of data integration solutions based on the next Web. The course will cover both theoretical aspects as well as concrete techniques to implement OSLC solutions through multiple examples.

Course Goals

  • Data integration scenarios and challenges
  • Web-based data integration
  • Open Services for Lifecycle Collaboration (OSLC)
  • OSLC Specifications
  • Standards for web-based data integration
  • Related technologies
  • OSLC adapter implementation
  • Apache Jena
  • OSLC Adapter tutorial
  • Conversion of data into RDF
  • Overview of existing open-source solutions

Who Should Attend

This course benefits project managers, systems engineers, data management experts, standardization specialists, and software developers.

Instructor

Dr. Axel Reichwein has developed since 2012 several OSLC-based integration solutions including OSLC adapters for MagicDraw SysML, Simulink, AMESim, and PTC Integrity, in addition to OSLC-based syn-chronization middleware, triple stores, SPARQL endpoints, and support for the OSLC Tracked Resource Set (TRS) protocol. Many of these solutions are available as open-source on GitHub at https://github.com/ld4mbse. He organized a 2-day Workshop on OSLC at the INCOSE International Workshop 2015. He co-authored an article on OSLC entitled Integration of MBSE Artifacts Using OSLC in the August 2015 issue of the INCOSE INSIGHT magazine. As Co-Chair of the OMG OSLC4MBSE working group, he investigated how OSLC can be used for data management in a broad engineering context. He received a PhD in Aerospace Engineering from the University of Stuttgart and performed postdoctoral research at the Georgia Institute of Technology in system architecture modeling and multidisciplinary data integration.

OSLC Adapter Tutorial Code

The OSLC adapter tutorial code will be shared to developers through a local Git repository packaged as zip file. Each new OSLC adapter concept is introduced through a specific Git commit. By using Git, developers can go back and forth in the history of the development of an OSLC adapter, or choose to start from scratch.
