The results of the 3rd ed. of Barometer Open Data show how governments, as part of its business as usual, are already collecting and managing a large amount of data in areas as diverse as cartography, cadastre, statistics, budgets and public spending, business records, legislation, transport, trade, health, education, crime, environment, election results or procurement.
In addition, more than three quarters of these official data are also available online in any way through the many web sites administered by the various government agencies. However, only a small proportion of all these sets of data already digitized (about 10 per cent) may be deemed to be really open database and, in addition, the great majority of them are concentrated in the 10 countries leads the ranking.
The five most widespread problems, organized according to, which have been detected in the study conducted by the barometer after analysis of data sets 1,380:
- Open licences: only 18 per cent of the data published are clearly associated with a license to use the data without any restriction beyond the attribution to the original source. This means that in the vast majority of the available data are restrictive licences or simply unknown, preventing their reuse.
- Data sets Únicamente incomplete: 32 per cent of digitized data sets that were analysed are published in a complete with a view to facilitating their download and use. Most of the data are currently fractured and spread among multiple sections of the published or even between different websites rendering their location.
- Not readable formats or reusable hardly machines: Just over half of the data (including a 55 per cent) are published in formats that, in addition to be readable by machines, can also easily be reused. The use of standardized formats is very limited, making it more difficult to interoperability. Likewise, proprietary formats are still in the majority by limiting access to those users that do not have the necessary software.
- Outdated data: up to 26 per cent of the available data are updated as often as it would be appropriate to their nature. Similarly, in most cases there is no indication as to what the update frequency forward. The outdated data lose much of their interest to potential reutilizadores.
- Rates of access: There is still a need to pay a fee to have full access to a 10 per cent of the data published. This not only severely restricts the target groups for the use of such data, but also contributes to increasing the digital divide.
All these problems directly affect distinctive features that are open data and are the key to its potential. While not comply with all these features will not be possible to obtain all social and economic benefits offered by the open database .
