Co-building a Digital Rubbing Archive with Metadata Standards
拓片数字档案的共建与元数据标准
标签：数字档案, 众包共建, 元数据, 开放获取
民间拓片档案正走高校图书馆路线：某金石爱好者社区以统一模板众包扫描——600 dpi 无损 TIFF、色彩卡入镜、正反两面拍摄，元数据按都柏林核心（Dublin Core）扩展"拓工、纸墨、递藏"三个字段，两年收录 4000 余幅并全部以 CC BY-SA 开放。关键经验：①上传端脚本自动校验 dpi 与色卡，不合格退回重扫；②同一版面不同拓本建立"版"与"拓"两级实体，可比较不同拓工的手法差异；③与博物馆合作时预先约定原始文件留存与署名权归属。
Amateur rubbing archives are borrowing library practice: one epigraphy community crowdsources scanning to a template—600 dpi lossless TIFF, colour card in frame, recto and verso—with Dublin Core metadata extended by three fields (rubber, paper and ink, provenance). Two years in it holds 4,000-plus rubbings, all open under CC BY-SA. Lessons: upload scripts validate dpi and colour card, bouncing failures for rescan; separate plate and impression entities let users compare different rubbers of the same design; museum partnerships settle raw-file custody and attribution upfront.
