How to return bonus bet365 cultural relics lost overseas，It is a hot topic in bonus bet365 academic circle。Chai Jianhong thinks，"First，Looking back on the past，We must understand history realistically；Second，Based on the present，Let’s actively promote cultural and academic exchanges；Third，Look to the future，I firmly believe that historical problems will be successfully solved”。It is difficult to return bonus bet365 cultural relics in physical form，This issue needs to be viewed objectively and rationally。Among the cultural relics unearthed from the Sutra Cave of Mogao Grottoes in bonus bet365，The absolute number is bonus bet365 ancient manuscripts and a small number of printed copies，Later scholars called it bonus bet365 Suicide Notes、bonus bet365 Documents。As of now，The bonus bet365 Academy has publicly accepted the most donations of bonus bet365 documents，The family of the late Japanese calligrapher Aoyama Sugiame returned eight bonus bet365 scrolls from their collection in October 1997，bonus bet365 cultural relics "return to their hometown"，Return to the cultural heritage site。

　Digital reconstruction of scripture cave bonus bet365

The return of cultural relic entities is difficult，Is it possible to explore other avenues？When an international conference was held in bonus bet365 in 2015，We propose the idea of ​​"digital return" of bonus bet365 documents。Before，In the “Thirteenth Five-Year Plan” of the former Ministry of Culture, a plan was proposed to “promote the return of overseas Chinese ancient books”。This provides a new model for the "digital return" of bonus bet365 documents。

How to integrate and utilize these resources，How to use information technology，Especially digital humanities technology to carry out academic research in humanities and social sciences，This is the library as an information provider、Museum、Issues that archives and digital institutions need to think about。Discuss storage in different countries、How to make bonus bet365 documents from museums and other institutions in different regions easily accessible to the public，Is a common topic faced by academic resource providers and academic circles。The good news is，April 26, 2015，The National Library of France and the bonus bet365 Academy signed an agreement，Agree to donate to the bonus bet365 Academy a high-definition digital copy of the bonus bet365 scrolls collected by the museum，Authorizes the bonus bet365 Academy to use these materials free of charge for non-commercial purposes。This cooperation，This is the first time that an overseas collection institution has donated digital copies of scripture cave documents to the bonus bet365 Academy on a large scale，This is also the first digital resource of scripture cave documents obtained by the bonus bet365 Academy。2016，The National Library of China completed the first phase of the “Overseas Chinese Ancient Books Bibliographic Database”，The National Library of France has donated high-definition digital resources of all bonus bet365 manuscripts in the French collection to the National Library of China，Including more than 2700 Chinese documents、More than 4,000 Tibetan documents，There is also Sanskrit、Uighur、Khotanese、Sogdian、Precious documents in Hebrew and other languages，Total more than 7,000 numbers。After，The Institute of Overseas Ethnic Literature of Northwest University for Nationalities completed the digitization and storage of 1,000 volumes of bonus bet365 ancient Tibetan documents in British and French Tibet，Building China’s first digital bonus bet365 ancient Tibetan literature resource library。

Under the promotion of bonus bet365 Academy，The National Library of France and the bonus bet365 Academy proposed to cooperate，Re-digitization of the bonus bet365 documents collected by the museum。Provide a high-definition digital resource to the bonus bet365 Academy upon completion，And adopt protocol authorization method，Let experts and scholars easily use these digital resources。If this project is successfully implemented，It will be a new model of "digital return"，Laying the foundation for the "digital reconstruction" of Tibetan Scripture Cave documents。

　For this purpose，The bonus bet365 Academy will establish a document resource sharing platform for the Tibetan Scripture Cave，Including catalog of Tibetan scripture caves、Research Directory、Image resources, etc.，can be classified、Search、Summary、Sort and data association，make research directory、Literature information、Full-text database and image resources and other information in the ongoing "Digital bonus bet365" project realize data association and one-stop retrieval。This will greatly facilitate scholars to obtain the precious resources of the Tibetan Scripture Cave，Thus breaking the disparity in the Tibetan Scripture Cave literature resources caused by the loss of overseas human factors to different countries、Restrictive barriers set up by institutions。

Whether the Tibetan Scripture Cave documents are “digital return” or “digital reconstruction”，The purpose is to build a digital resource sharing platform for Tibetan scripture cave documents，This is the storage and integration of digital resources of lost overseas bonus bet365 documents，It is also the "digital protection" of bonus bet365 documents，And achieve scalability，Building an intelligent information system for bonus bet365 resources for classified management of digital content。Protect and develop through digital technology，With the help of technology，While rescuing and protecting cultural heritage，Deeply explore the intangible value of bonus bet365 documents，For academia、Society、Public Services。

　Building a bonus bet365

Currently，There are not many bonus bet365 literature databases that are publicly available online，The one that is more recognized and used more frequently is the "International bonus bet365 Project" (IDP)，But it does not have a complete searchable catalog of bonus bet365 documents，Mainly established collection countries、The catalog that the collection institution has digitized，A complete catalog of Tibetan scripture cave documents has not been constructed；Although it has fully carried out the work of digitizing bonus bet365 documents，And achieved certain achievements，But the progress of digitalization is slow、Inconvenient to search。Therefore，It is necessary to establish a bonus bet365 literature catalog database，Described in terms of document types，After continuous modification、Supplement、Perfect，Establish a complete catalog database of published bonus bet365 documents。

The Tibetan Scripture Cave Documents Lost Overseas，Museums in different countries、Libraries and other public and private collection institutions，Major related institutions in my country also have collections，Can be distinguished in the metadata setting of database construction。Data collection of lost overseas bonus bet365 documents、Processing、Organization、Cataloging、Classification by collection location, etc.，And sort out the catalog of bonus bet365 studies，Combined with the existing digital resource platform of bonus bet365 Research Institute "bonus bet365 Studies Information Resource Library"，Through intelligent information association to the system，Using the resource library management platform expanded by the second phase of the "bonus bet365 Studies Information Resource Library" under development，Finally completed the data processing of the literature catalog and literature research catalog of the Tibetan Scripture Cave、Data Index、Data integration、Data association，Complete database content construction。

At the same time，This matches the research directory related to bonus bet365 documents，And conduct information management on both、View、Sort、Classification、Association、Search, etc.。After the project is completed，The main results are presented in the form of database，Can realize information retrieval on the same platform as the current "bonus bet365 Studies Information Resource Library"，It will greatly facilitate scholars around the world to use Tibetan Scripture Cave documents。At the same time, we cooperate with relevant foreign institutions to jointly build、Shared mode，Actively promote the internationalization process of bonus bet365 studies in the digital humanities environment，This is the real purpose of proposing "digital return"。

Development of database resource sharing platform，Mainly cooperate with China National Knowledge Infrastructure，Both in terms of database architecture and platform function design，Both have stronger technical advantages。"bonus bet365 Studies Information Resource Library" has been running for five years，Now proceeding to the second phase of platform upgrade，Just in time with this project，Better realization of docking and association of different resource types and heterogeneous databases。The platform is developed iteratively based on top-level design，SOA-based architecture、Unified user management and permission management，Componentization、Component development technology，XML-based data support and Web Service technology, etc.；Using computer cluster technology as a whole，Achieve dynamic automatic load balancing and other technologies。Based on the above factors，The system performs computer clustering according to service functions，Can effectively meet the reliability of the system、Scalability、Stability and operating efficiency。

　　Provide effective ways to obtain resources

Digitization of cultural heritage is the development direction of the information age，With the help of digital network technology，The exquisite murals of the bonus bet365 Grottoes and the scripture cave documents and other materials can be virtually reproduced or digitally reconstructed，And make researchers independent of time、Space limit，Convenient access、Comparison and correction，It will certainly greatly promote international bonus bet365 studies。Therefore，Accelerate the "digital return" or "digital reconstruction" of overseas bonus bet365 Scripture Cave documents，It is very necessary。First，Constructing the general catalog database of Tibetan scripture cave literature，Built to be searchable by domestic and foreign experts、combing、Summary、Classified database sharing platform，Laying the foundation for the future implementation of the "Digital bonus bet365" project，Exploring a path for technology development and implementation。Secondly，Connect the bonus bet365 Studies Research Catalog and the Library Cave Literature Catalog database，Implementation Research Catalog、Literature information、Full text of research literature and association of future implementations with image resources，Building a digital resource sharing platform。Again，Comprehensively organize the literature systematically、Published、Collection、Perform statistics on saving status, etc.，Provide a systematic searchable database for the academic community。Explore the "digital return" of lost overseas bonus bet365 Sutra Cave documents and jointly build them、Shared pattern，Let more experts and scholars、The public can share this precious cultural heritage resource，It will greatly promote the international spread of bonus bet365 culture。
