- 27. The price ofPSI: the “free data” approach • The peculiar cost structure of digital data collecting, processing and delivering (high fixed costs, zero marginal cost) strongly influences the possible pricing strategies to be adopted by PSI holders. • Pollock (2008): a price that equals marginal costs (i.e. PSI free of charge) is socially optimal provided that elasticity of demand and positive externalities overcome a given threshold. ✓ Empirics: those conditions are likely to be verified in most of the PSI domains. 27

Use HTTP URIs so that people can look up those names. 3. When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL) 4. Include links to other URIs. so that they can discover more things. Ref: http://www.w3.org/DesignIssues/ LinkedData.html 30
