VHL Portals Network
The Portals of the VHL instances reflect and express the operation of the three dimensions that integrate the operational framework of cooperative networking of VHL, which are: social networks, of contents and of learning and informed environments.
The portal of a VHL instance integrates the information sources, which are operated in a decentralized way in network represented through the formation of its contents network. In the same manner its social network is represented in the portal through information about the participating institutions of the instance, the advisory committee as well as through the publishing of documents produced by the network: meeting report, projects, work plans, matrix of responsibilities, and others. The learning and informed environments for interaction and exchange of knowledge among the actors of social network is represented in the portal, mainly in the incorporation of functionalities and communication resources in the network as well as by the record of information flows that are generated by social network, for example, by the news and debates in forums in the collaborative spaces.
The development of portals of VHL instances is based on patterns that aim enable the interoperability, the integrality and the convergence of the instances among themselves and among these with the regional portal of VHL. These patterns are applied to different elements that compose a portal: information architecture (navigation structure and organization of information sources), accessibility patterns (access to the largest possible number of people, independent of their physical conditions), drawing of interface (formatting contents for different accesses devices), visual programming and technological implementation.
Conceptually the portal VHL tends to be expressed as an aggregator environment of applications (widgets) developed by network web services of information sources. From this concept and considering that the spaces of collaboration in the Web should permeate its own environment of the portal, ensuring mechanisms and collaborations tools among the users in contents development published in its information sources, the aggregator concept (mashup) can be extrapolated for the development of these collaboration spaces and personalized spaces of users: “my spaces”. In this analysis in the context of VHL and its associated networks, the Regional Portal of VHL became more and more integrated to collaborative spaces of the user, be them related to context of regional information sources of VHL, or of a thematic VHL, other associated network and so on.
To facilitate the construction of VHL aligned to these patterns, the VHL Model offers an application for construction and management of the portal (main Page) of VHL, as well as the integration of its information sources. This application is the VHL Site (see Methodologies of Information sources of VHL > VHL Site)
The adoption of a same pattern of graphic design and navigation following the patterns and international standards is used to facilitate the access of users, increase the efficiency of VHL operation and with the intention of offer a well architected and structured environment. The interfaces presuppose the adoption of international patterns and set of standards and to create and interpret web contents (web standards). The separation between content and layout for example is what enables the production of access interfaces and publication of contents in different formats suited to various media, such as computer screens, printers, aural devices, handhelds, among others. The definitions of navigation and graphic design are detailed in the Guide of Graphic Design VHL.
The VHL instances can also develop Hot Sites e Knowledge Hubs as actions of communication related to commemorative dates and specific events in its thematic areas and regions promoting and disseminating selected and relevant content. The contents of these sites follow having the VHL as repository, from which they offer a showcase of highlights from strategies and researches pre drawn up.
Thus, the patterns applied to the portals of the VHL instances, are one more of the mechanisms that integrate the parts into a whole, giving the VHL the fullest realization of its network sense.
