3.6 Metadata Quality Assurance (MQA) 
The Metadata Quality Assurance is a c omponent to monitor the quality of the metadata that is 
harvested from other portals or sto red manually with the EDP metadata creation form. Currently 
quality measurement is ba sed on metadata schema violation against DCAT-AP 1.1 and availability of 
the dis tributions of a dataset.  The MQA is running checks on a weekly basis. Each check has a 
duration of a couple of days. This is due to the  HTTP GET requests against each single di stribution in 
the portal, checking their availability.  
In addition to the navig ation buttons in the dark blue bar at the top of the page, a drop down menu 
allows the downloading of a report file, in which all the data generated by the MQA is contained. The 
report is available in various formats. The PDF report includes the charts displayed. 
3.6.1 The Global Dashboard View 
This is the landing page of the MQA. It gives an overview of the quality situation across all catalogues, 
datasets and distributions in the P ortal. If the use r wants to  investigate the mentioned issues with 
datasets or distributions in detail, he/she can use the catalogue selection menue on top of the page 
to navigate to the selected catalogue details page. 
An information icon in the upper right  corner is indicating that the user can get explanation texts for 
all diagrams on the page. The introduction text shows the planned schedule for the next check to be 
performed by the MQA. The bottom of the page show s the date when the last check started. I f the 
MQA is currently running a check, then a spinning wheel beside the last check date is indicating this.
