当前数据库的理论意义早已超越了传统档案学范畴，并在数据驱动下构成了全新的认知和知识生产范式。数据库结构与人文研究形成同构关系，甚至在一定层面上直接预设了研究路径。元数据与本体的关系时常决定了研究者提问的方式与范围，不同类型的音乐数据库更是反映出差异化的知识组织逻辑。论文通过对音乐数据库类型学建构的梳理，并以作者亲自参与的音乐数据库实践为基础，深入理解元数据与本体结构类型对知识组织内在逻辑的映射，进而展望“以数据库为方法”的民族音乐学数字人文研究景观。

The theoretical significance of current databases has long transcended the scope of traditional archival science,constituting a new paradigm of cognition and knowledge production driven by data.The structure of databases is isomorphic to humanities research,and even directly predetermines research paths at a certain level.The relationship between metadata schemas and ontology often determines the way and scope in which researchers formulate questions,and different types of music databases mirror distinct knowledge organization logics.Through a typological construction of music databases and based on the author's participatory practice in ethnomusicology data-base,this study provides an in-depth understanding of the mapping of metadata and ontology structure types onto the inherent logic of knowledge organization,and it further envisions the landscape of digital humanities for ethnomusicology adopting“database-as-method.”
