The MIDI Linked Data Cloud

The study of music is highly interdisciplinary, and thus requires the combination of datasets from multiple musical domains, such as catalog metadata (authors, song titles, dates), industrial records (labels, producers, sales), and music notation (scores). While today an abundance of music metadata exists on the Linked Open Data cloud, datasets containing interoperable symbolic descriptions of music itself, i.e. music notation with note and instrument level information, are scarce. This is the MIDI Linked Data Cloud, a dataset that represents multiple collections of digital music in the MIDI standard format as Linked Data. At the time of writing, the dataset comprises 10,215,557,355 triples of 308,443 interconnected MIDI scores, and provides Web-compatible descriptions of their MIDI events.音乐研究具有高度的跨学科性，因此亟需整合多个音乐领域的数据集，例如目录元数据（作者、歌曲标题、发行日期）、行业记录（唱片厂牌、制作人、销量）以及音乐记谱（乐谱）。尽管当前关联开放数据（Linked Open Data）云平台上已存在海量音乐元数据，但包含可互操作的音乐符号描述——即带有音符与乐器层级信息的音乐记谱——的数据集却极为稀缺。本数据集即为MIDI关联数据云（MIDI Linked Data Cloud），它将多批采用MIDI标准格式的数字音乐馆藏以关联数据形式进行呈现。在本文撰写之时，该数据集包含308,443份相互关联的MIDI乐谱所对应的10,215,557,355条三元组（triples），并为其MIDI事件提供了兼容Web的描述信息。
