华夏家谱GIS的数据组织与系统架构

华夏文明源远流长,家谱、正史与方志共同构成了中华文明史的三个重要成分,其中,家谱以家族中的个人信息为基本记录单元,以人与人之间的关系为框架,形成了富有中国特色的对家族从空间分布到时间演化的完整描述体系,家谱资料的蕴含信息和记录粒度是其他历史资料所不能比拟的。家谱GIS扩展了现有家谱信息描述的概念,通过强化其中蕴含的空间信息,以家族谱系为基础,在空间信息技术的支持下,重构个人的空间活动,重现一个家族的兴衰、繁衍与变迁,实现从宏观到微观角度家族历史的全面地反映。本文分析了家谱与GIS的关系,提出了家谱GIS构建所必须的统一的历史地理时空描述框架;在此基础上分析了家谱中信息的组织模式,设计了的家谱的核心数据模型;在Web2.0理念下,以公众参与的开放式系统构建为基础,设计了家谱GIS的系统架构并进行了系统实现。

Data Organization and System Architecture of Sino-family-tree GIS

Family tree,official history and chorography jointly build the entire history datum in China.The family tree,also called pedigree,is much informative in society,ethnology,custom,geography,population,economy,people and religion.It is significant to carry the data mining and regularization work on family tree for reconstructing spatial-temporal pedigree,reproducing the civilization skeleton of China and developing the national culture as well as spirit.However,due to the lack of technology,the traditional record and expression pattern can not reflect the movement,rise and fall of the family in spatial and temporal space accurately.So Family Tree GIS conception was proposed and it is combined with GIS as its technology supporting.The spatial relationships underlying family tree are imposed and the reconstruction,integration and recurrence of the family tree is its core study content.In detail,Family tree data model and the spatio-temporal supporting framework are designed according to the characteristics of traditional family tree.And then,some key technologies used in building family-tree GIS are discussed especially such as SOA based on Web Service,XML and XML Schema technology,distributed GIS platform oriented the public and the Web 2.0,also technology of management and drawing mass vector data,technique of generation SVG based on DOT,asynchronous network calling and interaction based on AJAX,XML are discussed.Thirdly,the framework of family tree GIS was proposed and the prototype system was introduced in this paper.Finally,taking a family-tree as a study case,building,analysis and representation of the family-tree is discussed.The experiments have shown that the family tree GIS we proposed is a good approach for the study of conventional family tree,and it will be helpful for future researches on family tree.
