Digital Cultural Heritage Preservation Practices in Conflict Areas: Example of Saving Ukrainian Cultural Heritage Online (SUCHO)“Saving Ukrainian Cultural Heritage Online”(SUCHO)is an emergency digital cultural heritage protection action initiated by western digital humanists in the context of the 2022 Russia-Ukraine conflict. Within a few months after the outbreak of the conflict, the project rallied more than 1,500 international volunteers, mainly using open-source web archiving tools from the online community and customized metadata solutions, to back up the content of more than 5,000 websites and 50TB of data resources from Ukrainian cultural institutions in the form of online collaboration. After the second half of 2022,the project has entered the follow-up stages of content curation, publicity education and offline support, and produced various types of digital humanities outcomes. Through case analysis, the research believes that the success and sustained operation of the project cannot be separated from the key contributions of the online volunteer community, distributed web archiving, and coordination by the digital humanities team. Although the project itself has some limitations, such as the flaws inherent in the online volunteer community, it provides a bottom-up innovative solution for similar digital cultural heritage crises.
