Research On The Collaborative Service System For Cross Regional Digital Resources Of Hakka Cultural Heritage

It is a significant work that using digital technology to save,display and spread the material and non-material cultural heritage effectively.Digital technology digitizing the Hakka culture resources,it creates good condition for spreading,data servicing and sharing of Hakka culture resources.Due to the Hakka people and its culture are distributed in different areas widely,and the Hakka culture digital resources preserved by regional,it form the dispersion characteristics of Hakka culture data,to a certain extent,it has formed a new "information isolated island",limiting the sharing of the Hakka culture digital resources data services.In order to improve the sharing and utilizing of the Hakka culture digital resources in different regions,this paper attempts to bring the service aggregation technology and database middleware technology in the collaborative services of the Hakka culture digital resources in different regions,to achieve the combination of different sites of the Hakka culture digital resources and makes multi-site Hakka culture resources providing services collaboratively,and promoting the sharing of Hakka culture digital resources.This paper studies the collaborative services of the multi-site Hakka culture digital resources mainly from the following methods:(1)The theory and technique.The REST framework and applies REST style geographic information service in the map service of Hakka culture have been explained firstly.Then the REST style geographic information service,its hierarchical model and technique of multi-database middleware have been investigated.And the data resources of Hakka culture needed in this paper will be stated finally.(2)Service aggregation of multi-sites Hakka culture map data.For the complexity of digitalized map service of Hakka culture heritage,the service release and access method were stated on multi-sites Hakka culture map data service.And then the metadata specification,which matches the practical situation of Hakka culture map service,was stipulated.Meanwhile,the discovery mechanism and aggregating procedure has been raised for Hakka culture map service,laying a solid foundation for multi-service aggregation.(3)The data cooperative service of multi-sites Hakka tangible culture heritage.In view of the situation that the digitalized data was been independently stored in different sites of different areas and based on the investigation on multi-database middleware,the integrating mode and framework has been summarized of multi-sites Hakka culture data summarizes,its data storage regulation has been designed,and ultimately the cooperative service procedure for the data in different sites has been proposed based on multi-database middleware.(4)The realization of cooperative service prototype system of Hakka culture digitalized resources.The cooperative service prototype system of Hakka culture digitalized resources has been designed and developed,being able to provide requesters with Hakka culture map service of different sites.Meanwhile,the service data aggregation of the Hakka culture map could be realized to search the different Hakka culture map services by selecting different areas and achieve cooperative service.Being able to provide requesters with Hakka material cultural heritage data of different sites and display it.The collaborative service of Hakka cultural data between different regions is realized.
