4. Sharing economy Pods & apps (e.g. Common Bike)?
5. Social Linked Beer Pods & apps (e.g. Untappd alike)?
6. Digital Play-a-LOD apps (ontology games for kids)?
7. PLDN community website (with expert profiles)?

5. Solid Use cases? First ideas
8. Reference data Pods, apps and/or lookup services
9. Open dictionaries Pods & apps?
10.Law data Pods & annotation apps?
11.Open research Pods & apps (GO FAIR & EOSC-compliant)?
12.Health & fitness data Pods & apps (MedMij-compliant)?

data & Solid apps with React (Ontola.io)
20.…

7. Solid Use cases? Recent idea
21.Solid data management environments for small heritage
organizations that they can use to manage their collections
online in a uniform way and where their collection data
(e.g. text and images) is stored as Linked Data in Solid data
pods and can be easily shared with many other data users
and organizations (to create e.g. new citizens science
applications with data from multiple data sources)
22.…

8. Vision…, interlink data and knowledge from
different communities in a uniform way

9. Solid Use cases? First conclusions
Many good ideas, but activities are mostly ad-hoc and can have
different priorities over time, which threatens the speed of
development and the desired growth and adoption of Solid in the
Netherlands and worldwide
But what can we reasonably expect when we position the Solid
activities in a historical perspective of previous internet and web
developments? (see next two slides)

10. Internet growth & adoption patterns

11. Solid growth forecast (personal view)
• MIT Research project
• Inrupt
• Local communities
(e.g. PLDN + local leads)
• Global Solid
Movement
Community
Ecosystem
(internet scale)
???

12. Solid growth & adoption: Next steps

13. Solid activities: Solid Meetups
Local leads & activities:
• 9 apr 2019: Solid Utrecht (Pieter van Everdingen)

14. Solid activities: Curriculum & challenges
We would like to work with teachers & students from:
• Universities
• Academies
• Graduate schools
• Secondary schools
• …

15. Solid activities: Development activities
We would like to work with other data and developer
communities to get Solid on the agenda of their activities
(guest presentations/workshops, etc.), e.g.:
• Front-end/back-end/full stack developers
• JavaScript/React/Angular/Vue developers
• Solid development activities at Hackathons
• …

16. Solid activities: More business focus !
We would like to work with business developers to decide
which Solid use cases are most promising for further Solid
activities and also to get more business focus next to the
technical focus we already have

17. Solid activities: More structure & support

19. Solid adoption & growth: Your ideas !
Did we forget anything in the previous slides that would
help giving Solid more momentum?
