The 2004 Commission of the European Community publication “Proposal for a Directive of the European parliament and of the council establishing an infrastructure for spatial information in the Community (INSPIRE)” established an infrastructure for spatial information for the European Union. It also endorsed standard ISO-19115 and acceleration of the Spatial Data Infrastructure (SDI) within Europe: SDI had to be made accessible to any user via the internet. This is the context within which IDENA aims for integrated and open internet access to geographic information of the corporate Information System of Navarre.

IDENA Objectives
More particularly, IDENA objectives with respect to data include the establishment of five services: documentation, localisation, viewing, downloading and pay service. The documentation of all information will be done according to standard metadata definitions. The localisation service enables a search for information based on criteria of the INSPIRE directive through a metadata catalogue. The viewing service allows the free viewing of search results, both for metadata and data. The download service offers the free download of basic data. Finally, the pay service facilitates the dissemination of paid data through electronic commerce.
For the component part of the system IDENA objectives include development of a map viewer, implementation services for access to spatial data services and development of a features server (WFS), a coverage server (WCS) and a map server (WMS). Both the data and the component parts are based on the standards and protocols recommended by INSPIRE - ISO 19100 and Open Geospatial Consortium (OGC) - for interoperation with other SDIs on various levels.

Three-tool Portal
The IDENA portal consists of three main tools.

• Map Viewer, which enables viewing of spatial information of Navarre, querying and identification of features, connecting with other information servers that follow the same standards and protocols and visualising spatial data on other scales.
• Metadata Browser, which enables searching of metadata based on the INSPIRE criteria. The result is a list of five main characteristics (title, summary, editor, format and additions) and some data visualisation options.
  
• Shop, which includes the following tasks or elements: shopping cart, on-line downloads, physical product orders, payment, tracking of orders and authentication. The telematic platform of the Government of Navarre enables the purchase of geographic information using electronic signature, a payment method and Safe Electronic Communication. This utility is not yet operational in the IDENA portal.

• organising data to enable users to arrive at a better understanding of its contents, with as main results avoiding duplication and error and preserving investment in data
  
• facilitating transfer of data by offering information on, for example, file formats, volume and localisation
  
• on-line distribution of data by incorporating addresses from which files can be downloaded, either free of charge or prepaid, through descriptions of how to carry out the necessary steps
  
• facilitating search for data in a complex corporate database; metadata standards allow a user to make a query that is redirected to the various metadata catalogues registered in the main server and results in a list of metadata originating from differing servers
  
• avoidance of wrong use of data by description of origin, initial intended use and allowed processes
  
• assurance of integrity and safety of data.
