One of the types of information source that comprises the VHL is the set of components integrators (type 6, see in Typology of Information Sources), constituted through methodologies that define the function and purpose of the sources – such as definitions of the structure of fields, standardization of data description, among other aspects, expressed in the different manuals, guides and procedures. It also makes part of this set of methodologies, technological resources –applications, language protocols, among others – associated with each source of information. The technological resources in VHL are developed and adopted in a coherent manner and consistent with the function of information sources, with the objective of allowing its implementation and operation.

All the methodologies and applications that comprise the VHL, aim to promote and support the management and operation of the information sources in a decentralized way through network cooperation, expanding the visibility and accessibility of the content network.

The development of methodologies and applications is shared through the network, in a decentralized and collaborative manner, under BIREME coordination, seeking to involve and use the different competences installed in institutions in the creation processes from the information sources. The sharing of good practices in the use of methodologies and technologies in the VLH scope valorizes the transparency of interactions between all participants of the network, especially the intensive use of collaborative spaces.

The Developers Network (RedDes), for example, aims to strengthen the social network constituted by the developers of networks VHL, SciELO and ScienTI, promoting the development and innovation of services and products of information collaborative way in the network.

The information sources of VHL include collections of different kinds, according to the typology described in  Typology of Information Sources, which comprise referential information, full texts, directories, and others. The geographic and thematic instances of VHL decide upon the adoption of these sources, according with its demands and needs for specifics information.

Considering that the development of information sources is a dynamic process and is in constant evolution, the content network of VHL enlarges through a continuous process of innovation that seeks to meet the demands of the thematic areas and countries.

Following, the description of methodologies and applications that constitute the information sources of type 6 – Integration components, adopted by VHL instances and that integrate it into a single network:

LILACS methodology, created for the development of the index of Latin American and Caribbean Literature in Health Sciences (LILACS): to collect, organize and provide a network of bibliographic information about the scientific-technical health literature in the countries of Latin America and Caribbean. As a methodology, it comprises a set of manuals and technologies.

LILACS Bibliographic Description and Indexing Web (LILDBI-Web): a software that operates the supply tasks, maintenance and quality control of the information sources referential that follows the methodology LILACS in a decentralized way and online. The applicative is described on> Methodology and Technology > Guides, manuals and technical notes or> Methodology and applications > LILACS

Scientific Electronic Library Online (SciELO): Provides scientific newspapers on the Internet cooperatively in full text and free access through a set of policies, standards, guidelines, procedures and tools for execution of the functions of assessment and selection of magazines, as well as, for the preparation, storage, publication, preservation, control of use and impact of scientific journals operated by SciELO websites. The methodology is one of the components of the SciELO model available in details here.

Collaborative Spaces or Virtual Communities: facilitate and make possible the use of formal channels of communication through social networks that record, recover and expand the dissemination of its ideas and knowledge among its members asynchronously, without restriction of time and location. These web spaces have as main feature areas for insertion and sharing news, documents, images, discussion forums, chats and blogs, and others. The applicative and set of functionality to instantiate these spaces are available here.

Directory of Events (DirEve): methodology that allows it to collect, organize and make available data of scientific events about health, such as congresses, seminars and conferences promoted mainly in countries in Latin America, the Caribbean and in the global South. The technological platform for the DirEVE is described. Access here

Health Information Locator (HIL): methodology that allows it to collect, organize and make available metadata for description of sites and information sources available in the Internet, selected and catalogued according to quality criteria and international patterns. Access the set of manuals and computer programs HIL.

Health Legislation (Leyes) methodology that allows to collect, organize and make available a network of bibliographic information of health legislation in countries in Latin America and the Caribbean. Contains legal rules related to healthcare. Also it covers economic and social determinants that influence in health and are incorporated into international treaties and agreements.

Serials on Health Sciences (SeCS): it records and organizes collections of serial publications allowing the creation of a collective catalog of the cooperating libraries of VHL, enabling your access to publications via Portal of Health Sciences Journals and instances in cooperation with VHL. Access the contents of reference.

Graphic Design and Navigation: the interface graphic model and navigation of the VHL facilitates and increases efficiency of the operation of the VHL and the interoperation with associated instances, that is described here.

Health Sciences Descriptors (DeCS): structure the indexing of articles of scientific periodicals, books, congresses annals, technical reports, and other kinds of material in three languages and the form of vocabulary, also allows searching and recovering subjects of scientific literature in the databases LILACS, MEDLINE, and others. The DeCS follows the tradition of classification systems and respective list of headers of subjects which had been transformed into specialized vocabularies without, however, abandoning the structures of classification systems from which were originated. Its hierarchical structure is based on the division of knowledge into decimal classes and subclasses respecting the conceptual and semantic links. Its terms are presented in a hybrid structure of pre and post coordination. Its methodologies and components are available here.

VHL-Site: Manager of interface that allows creating and managing the portal of an instance of VHL, associated with others methodologies and technologies of VHL. Described here.

Family ISIS: The platform of systems ISIS, stores and recovers information from textual sources of bibliographical kind, operating full texts and directories, with high flexibility to generate and operate indexes of recovery and information. With a history of more than 20 years, it’s widely used in Latin America, Europe, Africa and Middle East, the platform has an important role in the expansion and enriching of the set of solutions for libraries, information centers or in other global areas.

The BIREME maintains and provides applications based on technology ISIS, available on at and that are: XISIS, Wxis-modules / Wxis-php, CISIS, WWWIsis e ISIS-DLL – CDS/ISIS.

Interface for Access on Health Information (iAH): retrieves the information from databases in the Internet or Intranet in an integrated manner and, as one of the integration components, allows the operation, between different instances of VHL. The application counts on manuals and reference guides, available here and has been evolved together with WWWISIS for support new functionality with iAHx denomination.

iAHx: it improves the mechanism iAH of presenting search results in the VHL instances, allowing the visualization of the information sources in a integrated manner, individualized, ordered by pre-determined criteria and selected according to user interest. The component description, in details, can be accessed at here (in Portuguese).

mBVS: it enlarges the availability and portability of the national, thematic and regional instances of the VHL network, allowing access via mobile phones and mobile devices. The initiative coordinated by BIREME is developing with action lines that are being disseminated, but with not yet available technology for the VHL network. More information on  

Timeline: it records events chronologically organized, and presented graphically in form of a timeline, highlighting key dates and/or periods. The component is recorded in the guides and manuals

This set of methodologies and technologies aims to incorporate different networks of sources and information flows, promoting the convergence of social networks, of contents and of learning and informed environments by various geographical and thematic instances in an VHL only network. For this, the VHL network, as a cohesive structure with its participants instances of an organic gear, adopts the central concept of interoperability in organizing its information sources, this subject will be detailed in the next section.
