The document discusses open data and how it can be used to understand the world. It describes how open government data and open data in general can increase transparency and create value when more people can access and utilize data. The document outlines possible paths for organizations to publish open data, factors for success, and how to ensure quality. It also discusses combining data from different sources and using standards to better integrate and link open data.

• What are possible paths for organizations
that want to make open data available?
• Start small or think big?
• What organizational and technical success
factors exist?

21. Quality and provenance
• Within the publishing organization, how is
data quality assured, maintained and
communicated?
• How can developers ascertain that the data
used has sufficient quality?
• What are limitations to the sustainability of
applications built on open data?

can be most easily reused?
• How to enable the discovery of relevant
data within the multitude of available data
sets?
• How to enable applications to integrate
data from large numbers of formerly
unknown data sources?

★★★★ All the above plus, Use open standards from W3C
(RDF and SPARQL) to identify things, so that people can
point at your stuff
★★★★★ All the above, plus: Link your data to other
people’s data to provide context
