Next graph represents the reusability in terms of MELODA metric for every scope of information source and different types of information.
It shows a remarkable difference between those sources coming from national scope and those coming from local and regional. It is related also, that most of the data sources coming from national sources are older (with less attention paid to reusability).
This graph only describes current situation of PSI data sources in Spain and it is the first in its kind currently (Nov 2013). It is created by classifying the data sources by scope and type of information and averaging the MELODA index. Y-axis reflects this average.
