GIS-based family tree system integration

With the advancement of electronization and digitization of family tree, information sharing and function integration have become the bottleneck of the development and application of family tree. To address the problems such as the existing family tree systems are mutually closed and incompatible, family tree information representation is incomplete and non-standard, time and space information implied in family tree information is not well excavated and expressed, family tree information is repeatedly collected by each system, this paper proposes to parse and position family tree information under the Consistently Spatial-temporal Framework by using GIS technique, in order to regularize the expression and sharing of family tree information. Absorbing the VGI idea, people are encouraged to collaboratively collect and share family tree information. This paper discusses some key issues about the integration of family tree systems from aspects of the Consistently Spatial-temporal Framework, information sharing, interoperability, application mode etc. It designs a prototype of integration framework of family tree systems based on GIS and implements it by taking HXJP-GIS system and DZP-PGV system as an example. The practice indicates that the framework is feasible. It provides some new conceptions, reference methods and technical supports to construct the Chinese Family Tree Database and Platform for better protecting and utilizing family tree.
