  23. 23. 23 13/3/201813/3/2018 CHALLENGES CONCRETE CASES: THE ESCO QUALIFICATION PILLAR Qualification The good and the bad Stakeholder commitment and knowledge of what to do  huge success! Why do I need to open up my data? Are HTML and PDF enough? No “real” open data For how long do I need to keep my data open? Problem in understanding technology

Use LOD Quality Assurance Frameworks – They do exist! Follow the EIF and its tools (SATs, EIDAS, …) – implement Interoperability Roadmaps
