Resumen
Existen escenarios donde la información que gestionan los usuarios tiene una dinámica tal
que hace difícil su modelado, tanto por el contenido como por el grado de colaboración. En
muchos de ellos, un documento geo-referenciado, colaborativo, con imágenes y enlaces a
otros recursos, incluidos multimedios puede recoger la información necesaria. Para la
gestión colaborativa de estos documentos están concebidas las Wikis, una de las
herramientas fundamentales de la Web 2.0. Con el fin de brindar soportes geográficos
algunas de estas plataformas incorporan extensiones desarrolladas, generalmente, de
manera independiente a los estándares de las Infraestructuras de Datos Espaciales (IDEs);
las que rigen lo concerniente a la información espacial en la Web. Esta independencia
constituye una limitación para la generalización de las extensiones y la integración con
otras tecnologías de las IDEs más maduras como son los servicios de catálogos, de mapas y
de objetos geográficos. Este trabajo ofrece una definición e implementación de una
plataforma llamada GeoWiki que logra la integración entre los métodos propios de las
Wikis y los estándares IDEs, a partir de una extensión espacial a uno de los motores Wikis
existentes. Los servicios espaciales que incorpora mejoran la colaboración, pues garantizan
la vinculación de geometrías tipo puntos, líneas y polígonos, personalizaciones de estas,
ediciones espaciales de tipo “lo que ves es lo que obtienes” que generan texto wiki
correspondiente y búsquedas de contenidos con referencias espaciales enmarcadas en un
contexto geográfico.
In some scenarios, users face a challenge while editing documents because they have to manage complex information in a collaborative environment. In many of such scenarios, a document includes georeferenced content, images, text and links to other resources like multimedia content. Well-known tools to manage this kind of document in a collaborative environment are the Wikis, an essential kind of tool in the Web 2.0. In order to provide access to geographical content, some Wiki platforms include in-house developed extensions. Such extensions are often developed without following any standard of the Spatial-Data Infrastructure (SDI) which contain the guidelines regarding the usage of spatial information in the Web. The lack of support for the standards has two consequences: i) it is hard to generalize such extensions to many Wiki platforms and, ii) it is quite complicated to integrate them with more mature SDI technologies as services of catalogues, maps and geographical objects. We propose in this work the definition and implementation of GeoWiki, a platform aims to integrate features of Wikis and the SID’s standards based on a new defined extension to an already existent Wiki engine. The proposed extensions improve the collaborative work as well as the quality of the edited document because it provides new features like: linking of geometries as points, lines, polygons and any combination of them; “What You See is What You Get” editing which is able to generate spatial Wiki contents and; searching content with geospatial references.
