There are new or refurbished open data portals to be announced.

Switzerland just published in a new look for a better presentation of data. See the press release.



The European Commission published some months ago the European Data Portal.

snip_EuropeanDataPortal is much more than a collection of open data. It is an ecosystem with lots of documents explaining and promoting open data.


SPARQL inside!

The portal offers metadata as linked open data with an SPARQL endpoint for powerful searching.


select ?theme (count(?theme) as ?count) where {?s a dcat:Dataset . ?s dcat:theme ?theme} GROUP BY ?theme LIMIT 100  gives all  data categories/themes and their number of datasets .

Impact studies

Most of all these data are already published on other websites. The advantage of such open data portals are a centralized access and clear licence information, A main intention is to attract developers, to foster data usage and with this economic growth.

A Swiss study (January 2014) assesses the economic impact of Open Government Data: ´The report determined that the economic benefits from OGD for Switzerland lie most likely between CHF0.9 B and CHF1.2 B´.

European Study (November 2015) within the context of the launch of the European Data Portal got these results: “The aim of this study is to collect, assess and aggregate economic evidence to forecast the benefits of the re-use of Open Data for the EU28+. Four key indicators are measured: direct market size, number of jobs created, cost savings, and efficiency gains. Between 2016 and 2020, the market size of Open Data is expected to increase by 36.9%, to a value of 75.7 bn EUR in 2020. The forecasted number of direct Open Data jobs in 2016 is 75,000 jobs. From 2016 to 2020, almost 25,000 extra direct Open Data jobs are created. The forecasted public sector cost savings for the EU28+ in 2020 are 1.7 bn EUR. Efficiency gains are measured in a qualitative approach. ”

Next: LOD

Open and machine-readable formats help to access data and foster the economic impact. Even better when the data have metadata in a standardized description. Linked Open Data (LOD) in RDF format provide this; uses this format describing the harvested datasets (metadata). The next step will and must be data in this format in order to link masses of data in the linked data cloud.

With a first step is been made in Switzerland.
