The survey studies existing open data platforms, focusing on the technical aspects. We surveyed over fifty Open Data repositories operated by national, regional and communal governments, as well as international organizations. Features such as standardization, discoverability and machine-readability of data were taken into account. Furthermore, a subset of five repositories was examined in more detail, additionally analyzing data and metadata quality.
The results of the survey were accepted paper at the Web Science Track@WWW'12 ("The State Of Open Data - Limits of Current Open Data Platforms", [bibtex].). The raw data on which the paper is based can be downloaded on this page.
