Analysis of the Spanish case

The model analyzed only studies the line 1 in the scheme of the global model, meaning the relation between the revenue for the professional re-users and the reusability of information.
Next illustration describes the elements of the proposed model to be checked against the data of the Spanish Market.

PSI Policies
Public Sector Information policies represent those regulations and action plans from the public administrations stimulating the publication of information and how to do it. As described in the economical background point there are strong differences between market potential estimations and actual data.
It is supposed, and this research tries to provide some modelling, that these policies will report benefits for the society, and that some of these benefits will be economical. To what extent should be determined in order to set the right amount of support to those policies.
Technical standards
Technical standard represents the technical mechanisms implemented by the public bodies in order to release the information. They could range from closed standards (so the re-user has to purchase some licensed tool in order to access the information) to open standards with additional meta data enrichment.
Access
Access represents the procedures needed for the re-users in order to retrieve the information. It could range from manual request (even not online) to an online request that could provide a single data into the dataset connected with other data in different sources.
Legal
Legal represents the license that the public body provides to the released data. Could range from copyright (and therefore, no rights to reuse) to only attribution. Other ‘minor’ differences are the request of not to distortion the information, and include updating dates in the reuse.
Interoperability
Interoperability will represent the extension and diffusion of how the structured information is released. It could range from a global standard with world-wide adoption to a, do it yourself, and no agreement on the structure of the information.
This factor has not been considered in the practical part of present study but it is noted here because some hints within the analysed data seems to assign it an important role.
MELODA
Three out of the four described factors compose MELODA metric. And in a close future interoperability will be included as well.
Reusability
It is the composed characteristic of released information which makes them simple, inexpensive, legal and connectible to other sources. It is composed of these 4 factors although in this analysis, only three of them have been included.
Scope
Scope represents the geographic range of affected information. It could range from local to international.
Type
Type represents the different types of information. In this work MEPSIR classification will be used in order to make possible the analysis with the provided data (MEPSIR, 2006).
Economic impact
It is the real dimension that the society should take into account in order to determine the level of investment on PSI policies. Available analysis are quite partial as long as they only includes direct effects and possibly without a full coverage of the affected companies. A more general analysis should come from models like depicted in the global model.
