A methodology for comparing and measuring Open Data Social Value

There are different dimensions to support the assessment and benchmarking of the social value of open data initiatives. We propose a methodology that compares and evaluates open data social value according to a spectrum of measures going from intensional completeness to subjective  meaning. We first suggest that open data made available online by an organization can be modelled in terms of the corresponding integrated conceptual schema, as a uniform construct. Then, a global schema is created with the integrated schemas, and intensional as well as extensional social value on data can be defined over such conceptual schemas.

UnifiedViews 2.0 – What’s new

UnifiedViews logoUnifiedViews is an Extract-Transform-Load (ETL) framework that allows users – publishers, consumers, or analysts – to define, execute, monitor, debug, schedule, and share RDF data processing tasks. UnifiedViews is one of the core components of  Open Data Node – publication platform for Open data.

The data processing tasks may use custom plugins created by users. UnifiedViews differs from other ETL frameworks by natively supporting RDF data and ontologies. UnifiedViews has a graphical user interface for the administration, debugging, and monitoring of the ETL process. In this blog post, we focus on the description of new features of UnifiedViews 2.0, which was released on April 2, 2015; please see the website for documentation of UnifiedViews, to get information how UnifiedViews may be obtained, and to see the community around UnifiedViews.

Understanding Data Accessibility

In current practice there are two distinct methods how to facilitate access to the data:

  • batch access implemented by making available files with contents of dataset
  • query based access to selected parts of data available through application interface (APIs)
