    dcterms:description """The dataset of [EU Digital Agenda Key Indicators](https://digital-agenda-data.eu/datasets/digital_agenda_scoreboard_key_indicators) contains statistical information about the European information society. The dataset is composed of a series of statistical observations with various properties and a very regular structure.

This is a large, typical dataset with statistical information, with a very regular structure. In contrast to [linked-spending](https://w3id.org/riverbench/datasets/linked-spending/dev), this dataset does not include textual information and is more homogenous, making it an interesting comparison point for aggressive compression algorithms."""@en ;
