Comparison: Amount of published datasets in some national data catalogs


To provide a better picture about status of OpenData in countries where COMSODE consortium members are located, here comes a basic comparison of the amount of published datasets in national data catalogs.

For the sake of speed and efficiency, I’m including numbers from catalogs which provide publicly accessible API: Czech Republic (CZ), Italy (IT) and Slovakia (SK).

To have better reference, also numbers from Austria (AT) and UK data catalogs are included.

number of datasets 195 6644 205 1043 16662
number of resources 1689 87073 512 11164 113544
number of datasets with open license 22 (11.3%) 1102 (16.6%) 1 (0.5%) 1041 (99.8%) 8723 (52.4%)
number of datasets without open license 173 5542 204 2 7939

Some observations

  • Czech Republic and Slovakia are far behind others when it comes to both total number of datasets and number of datasets with open license, with UK taking the lead.
  • Austria has almost all of its datasets clearly marked with open license.
  • There is a big difference between Slovakia and Czech Republic when it comes to number of resources. While number of datasets is similar, this may be attributed to different dataset cataloging methodologies being applied in both countries.
Sources and methodology

API of each particular data catalog was used:


Counts are obtained using simple “list” and “search” queries, no filtering or evaluation applied.

Whether the dataset is licensed under open license is determined using “isopen=true” attribute.

    Hi, I would like to know the source of Czech national catalogue. Based on the fact that Czech National Open Data catalogue does not exist. Could you please provide some source for Czech one? Thanks.
