The implementation of persistent identifiers for spatial objects is one of the most immediate challenges in the implementation of the INSPIRE Directive. Nowadays, some EU Member States have governance structures, processes, standards, guidelines and tools to create, maintain, manage and use persistent identifiers in their respective SDI. However, their approaches are different and their initiatives present different levels of maturity. INSPIRE currently recommends the use of HTTP URI for the implementation of those persistent identifiers. In addition, it is considered a good practice to enable resolving or dereferencing these URIs. For example, resolving the HTTP URI of a spatial object will result in downloading a file that represents the spatial object. However, the challenges that such recommendation implies (e.g. governance, cost-effectiveness, etc.) have not been addressed by the INSPIRE Directive neither the Commission Regulations that develop it. Moreover, INSPIRE will not going to organise a common framework. That is, each EU Member State will establish and manage their own framework with their own resources. The implementation in Spain of INSPIRE identifiers is conditioned by national norms such as the National Interoperability Framework (ENI), which is aligned with the European Interoperability Strategy and the European Interoperability Framework, and the Spanish Technical Standards for Interoperability (NTI), which implement the ENI. An example is the NTI for the Reuse of Information Resources that sets out the basic guidelines for the use of HTTP URI for identifying reusable information published by public sector entities. Another determining factor for the implementation of INSPIRE identifiers is the high degree of organisational and territorial dispersion of the production of spatial information among public bodies in Spain. All of these kinds of constraints can be found in other Member States of the European Union. This submission shows the progress made so far in the development of a solution to the challenge posed by HTTP URI in Spain given the aforementioned conditions. This solution should be able to register these HTTP URI as persistent identifiers of INSPIRE spatial objects and later extend this register to other kinds of INSPIRE resources, such as spatial datasets. In addition, the solution should be able to resolve HTTP URI into queries to INSPIRE download services. In other words, this solution will allow the implementation of a framework for resolvable persistent identifiers for INSPIRE resources in Spain.
