1. Bridging the Paradoxes of the Commons 2.0

2. Semantic Web: The Common Ground

3. Data Metadata Making Sense Creating Value

4. True and Fair Metadata?

5. Approaches Inferring data about data from the data (e. g., Google PageRank) Getting people to create metadata („harness self-interest, not volunteerism“, i. e. make their effort pay)

6. Making Sense: Beyond the Trivial?

7. Is Not Trivial At All Same thing has different meanings in ever changing contexts. What lies beyond foaf, or booking tickets? How to foster innovation at this layer?

8. Where Does The Value End Up?

9. Sharing the Surplus Providing Data Inferring Metadata Making Sense Creating Value

10. Whose Property?

11. The Property Trade-off Common property + No exclusion - Freerider and incentive problem Private property + Transactions, incentives - Welfare losses from monopoly pricing and structural undervaluation due to uncertainty(?)

12. Intellectual Property?

13. Some Intuitions Copyright might apply to data and metadata. Metadata might be derivative works. Making-sense-innovations will often be patentable. Possession will impact strategies and profit sharing.

14. The Emerging Picture

15. Semantic Web ≠ Web 2.0 Data Metadata Making Sense Creating Value Data Metadata Making Sense Creating Value

16. Intermediaries Commercial incentives drive real-world innovations in the Web 2.0. (Think Google, Facebook, etc.)

17. Issues Licensing of data, Framing choices? Infrastructure of metadata? A „GPL“ for data and APIs? Common carriage for private intermediaries?
