What is a dataset?
Datasets can be defined as data that are "related, suitably structured and organized so they can be appropriately treated (processed) to obtain information" (definition extracted from Open Data. Strategic guide for its implementation. FEMP minimum data sets that should be published.).
Every dataset comprises one or more resources or distributions, available in different formats (file, web service, etc.). By reusable formats we refer to structured data formats, which can be read or interpreted by automatic machines. Likewise, these formats are called open formats if it is not a copyrighted format.
