The portal is public-centred, which means its content is organised on the basis of the types of people accessing the site and their specific information needs.
The basic information is presented in a clear and easy-to-understand manner, and the different sections of the site cover the possible needs of every user.
The site is supported by a detailed subject thesaurus and a parallel system, to make it easier to search the content and bring up directly relevant material. This classification allows an effective search both of full texts and of terms in the subject thesaurus.
At the same time, users are provided with a set of web tools and the relevant institutional framework, and there is an attempt to avoid the use of unfamiliar terminology, with constant explanation of the terms referred to.
The site code has been checked both in terms of accessibility on the basis of theWeb Content Accessibility Guidelines V.2 of W3C and in terms of the general applicability of the code (based on the standards of theW3C World Wide Web Consortium).
