The newest version!
/*
* SemanticWebBuilder es una plataforma para el desarrollo de portales y aplicaciones de integración,
* colaboración y conocimiento, que gracias al uso de tecnología semántica puede generar contextos de
* información alrededor de algún tema de interés o bien integrar información y aplicaciones de diferentes
* fuentes, donde a la información se le asigna un significado, de forma que pueda ser interpretada y
* procesada por personas y/o sistemas, es una creación original del Fondo de Información y Documentación
* para la Industria INFOTEC, cuyo registro se encuentra actualmente en trámite.
*
* INFOTEC pone a su disposición la herramienta SemanticWebBuilder a través de su licenciamiento abierto al público (‘open source’),
* en virtud del cual, usted podrá usarlo en las mismas condiciones con que INFOTEC lo ha diseñado y puesto a su disposición;
* aprender de él; distribuirlo a terceros; acceder a su código fuente y modificarlo, y combinarlo o enlazarlo con otro software,
* todo ello de conformidad con los términos y condiciones de la LICENCIA ABIERTA AL PÚBLICO que otorga INFOTEC para la utilización
