¿Cómo se usa Dublin Core? September 13, 2007

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    En el artículo titulado “Qué es Dublincore”, podemos encontrar la definición de este término, pero en este otro artículo, lo que vamos a ver, es como se emplea.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              Dublin Core presenta dos niveles: el nivel simple o sencillo y el avanzado. El nivel sencillo de Dublin Core contiene quince elementos, mientras que el nivel avanzado aporta tres (Audiencia, Origen y Titular de derechos), además, de un grupo de elementos refinados que se ocupan de la semántica de los elementos de manera útil para el descubrimiento de recursos.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               Cada elemento de Dublin Core es opcional y se puede repetir. Dublin Core Metadata Initiative ha determinado formas estándar para utilizar los elementos y promover el uso de codificación y esquemas de vocabulario, aunque no hay ningún orden prescrito en Dublin Core para presentar o utilizar los elementos.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   Podríamos definir brevemente cada uno de ellos de la siguiente manera:

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               Título:El nombre que se da al recurso. Normalmente, un Título es un nombre por el que el recurso es conocido formalmente.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        Materia: El tema del contenido del recurso. Normalmente, una Materia se expresa como palabras clave, frases clave o códigos de clasificación que describen el tema del recurso

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          Descripción: Debe dar cuenta del contenido del recurso. La Descripción puede incluir: una introducción, una tabla de contenidos, una referencia a una representación gráfica del contenido o texto libre que de cuenta del contenido.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        Tipo: La naturaleza o género del contenido del recurso. El Tipo incluye términos que describen categorías generales, funciones, géneros o niveles para agregar contenido. Lo más recomendable es elegir un valor de un vocabulario controlado.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    Fuente: Una Referencia a un recurso de la cual el propio recurso se deriva. El recurso puede derivarse del recurso de la Fuente totalmente o solo en parte.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      

Relación: Una referencia a un recurso relacionado.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  Google Académico ordena los resultados de tu búsqueda por orden de relevancia. Así, al igual que sucede con las búsquedas web en Google, las referencias más útiles aparecerán al inicio de la página. La tecnología de ranking de Google toma en consideración el texto completo de cada artículo, así como el autor, dónde fue publicado y con qué frecuencia ha sido citado en otras fuentes especializadas.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           Por otro lado, Scholar Google se sirve de las bases de datos de CINDOC, OAISTER, dialnet…En definitiva, de los centros privados.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               Ante esta realidad, mucha gente considera que las posibilidades tecnológicas y de difusión de Google, de las que los centros bibliotecarios privados carecen, hacen a Google Académico, un buscador especializado sin competencia.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    Algunos creen y piensan que estas herramientas quedarán, en un futuro no muy lejano, como recursos de bibliotecarios para bibliotecarios ya que la mayoría de la gente prefiere lo más sencillo y barato, es decir, Google Académico.
