OPEN DATA REUSE IV
In version 5 of MELODA, some of the ideas proposed by experts have been examined and the assessment of each level has been revised. In this version, each level is assigned the value it has (1, 2, 3, 4 and 5). To evaluate the degree of reuse of each dataset, two measurements are used: 1) the sum of the scores obtained in each dimension, and 2) for each dimension a descriptive analysis of the frequency of each level is carried out. The first measurement will provide a ranking of datasets according to their degree of reusability; while the second allows us to have a more detailed image for each dataset and identify which dimensions need to
be improved (Abella, Ortiz-de-Urbina-Criado, De- Pablos-Heredero, 2019: 6).
Additionally, to classify the datasets based on MELODA 5, three categories of degree of reuse have been created (Table 3): from 8 to 23 points (the lower end is the sum of category 1 of the 8 dimensions) is inappropriate; from 24 to 47 points (the lower end is the sum of category 2 of the 8 dimensions) is basic; and from 48 to 61 points (the lower end is the sum of category 3 of the 8 dimensions) is advanced.
