In the portal's datasets, you can view their star rating according to the guide developed by Tim Berners-Lee. This system shows the degree of openness and technical usability of a dataset.

The first star is awarded to any data that is open at a basic level and available under an open license. We can find PDF files or image formats such as JPEG, PNG or TIFF, which are difficult to reuse.

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.

Publishing information openly from public administrations makes it possible to promote the institutional transparency and increase the confidence of citizens. It also enhances the involvement of society as a whole in policy issues and contributes to more effective decision-making through the analysis of data. 

Open access to data also provides an opportunity for companies, both large and small, to create new services, boost their efficiency and identify new business opportunities.
