Metadata quality
Automatic Approach
• Part of the Continuous Integration process
• Weekly „Link checking“
• False negatives due to timeouts, rate limiting etc.
• Issues have to be solve decentrally.
• Continuous Validation
• Can identify bugs, but
• Validity is just an indicator for quality

Editor's Notes
So obviously open government data is a compound word which is worth Looking at in detailThere is data, there is government and there is the opennessOpen does not only mean that it is available for free, that’s rather publicIf data is made open, we don’t mean public data, open data means:Piece of content which is free to use, reuse and redistribute by anyone, only constrained by the needs to attribute the authorRespectively the source and/or share it under a similar license, like in the case of this Venn diagramThen we have the government which works with data because it’s part of their daily routines (government data)Open Government would meant hat the government works in a transparent fashion to the peopleAnd only in the middle we have all topics united, so the definition I gave you on open data + government contextWhy is open government data is something desirable? The motives are:Transparency: In a vital democracy it’s good if everyone has at least to some extend the possibility to control the governmentInnovation: Because with data that concerns many people the chances are high that you can something useful with itParticipation: If you know what’s going on you can act accordinglyEfficiency: Because people can put data to use that government organization haven’t thought of yetThe core elements to make open government data is: machine-readability, licenses (determine openness), accessibility so it is easy for as much people as possibleNow, these concepts have a really nice sound, but also they are very abstract and get a boring connotation if you hear them over and over againOf course there are these great examples of open data where their usage has saved millions of taxes in health care etc. but let’s look at examples which are more in out own reach, for instance if we want to reach out for fruits
