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

LESSONS
CONCRETE CASES: THE ESCO QUALIFICATION PILLAR
Qualification
Publish raw data and not HTML or PDFs – make data Reusable
Add metadata – make data Comprehensive and Interoperable by a wider public
Use contextually - intuitive links to optimize data browsing – make data Findable
Data stored in stable locations and encoded in URIs – make data Accessible
Use open licenses like CC 4.0 and implement license conflict mechanisms – make data Reusable
Open Standards and Tech Stacks are now mature!  use them!
Use LOD Quality Assurance Frameworks – They do exist!
Follow the EIF and its tools (SATs, EIDAS, …) – implement Interoperability Roadmaps
