Legal reusability is the characteristic of a dataset to allow reuse in different ways from private to fully commercial uses. In views of this study five levels have been standardised. Importance of legal licensing has been analysed (Jasserand & Bernt, 2012). They remark the importance of copyright licensing and provide recommendations on setting clear licensing models of the information released.
Next table shows the five levels included in this dimension. Other legal considerations (i.e. restriction of malicious use of the released information, attribution, misuse, requirements to include the last update’s date, etc.) are not considered, because most of cases they are required as a group and does not limit potential fair uses of the information (Limits the illegal ones). An author cannot waive the attribution right accordingly to the Spanish legislation.
Additionally levels are weighted in order to provide a fair comparison.
| Description |
% weight |
| Level 1.Copyright. Data sources in this level reserve the copyright of data, thus restricting unauthorized use |
0 |
| Level 2. Private use. Data sources in this level will allow the use of the data without processes of approval but only for private uses. Not public use is allowed. |
10 |
| Level 3. Non-commercial reuse. Data sources in this level will allow data reuse but they do not allow commercial uses of the information re-use.(i.e. For a blog, for a non-profit organization) |
25 |
| Level 4. Commercial reuse. Data sources in this level will allow re-use of data, including the commercial reuse.(i.e. For any company in order to create new visualization of data) |
90 |
| Level 5. Only recognition. Data sources in this level will only ask re-users the attribution of the data.i.e. Releasing data with CC BY license. |
