Abstract
It is possible to outline three foundational elements for a new PPGIS approach: i) central position of the web site, ii) low specialized open technology and iii) system start up in relation to existing social contexts. Referring in particular to the first element we compare some essential features of the OCSs with the fundamental elements of a collaborative web environment for 'plan-images'. On this basis we define the general architecture of an open content system for planning processes composed of five principal areas: Images, Authentication and contacts, Links, Forum and Tools. At the present state of implementation of the participatory planning web-system only the basic characteristics of the architecture have been taken care of (the management and interaction of users, and the representation and management of the discussion on plans). Aspects, in the above architecture, such as 'links' and 'tools' have been disregarded so far, in order to better focus on basics. One result of such a kind of focalization has been the unification of the forum and images concerns. In fact we realized soon that the representation of all data concerning the discussions about plans is actually the place where images are implicitly available. Another conclusion we can draw is that the decision not to define a specific user type for the independent technical experts seems to be the right one. Also the distinction between official and non-official 'images' seems an aspect to preserve, as it has been welcome. Getting to some more 'functional' aspects, we saw that user-activation is likely to follow automatically user-registration (leaving the admin with the responsibility for later check upon the new user). However, not only the aspects cited till now but all functional aspects of the system should be reconsidered and deepened to increase a kind of access and interaction on site the most flexible and free and, in the same time, the most visible and traceable.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
