The first star brings a number of benefits for the consumer of the data as well as for the publisher. Consumers can view and print data or download data to a personal computer or USB flash drive, enter the data into any other system, perform analysis and share it with anyone they want in the way they want.
For the publisher, it is simple because there is no need to stick to the formats used. In addition, it will not be necessary to explain repeatedly to all those interested in the data that it can be used for any purpose, as long as it is distributed using an open license.
Publishing data on the Web in any format under an open license is a major step in opening data. However, data consumers might find it difficult to extract the data from these documents without having to manually type them into other systems.
