NPM ecology network dataset

The dataset contains the dataset of the NPM ecology network. npm_openrank_top100.csv file contains the result of top 100 OpenRank repositories in npm ecology. npm_ecology.json file contains the original network of npm ecology open source repositories, use `CALL apoc.import.json('npm_ecology.json')` to import the network into Neo4j database. npm_ecology.dump file is generated by Neo4j dump command, use `bin/neo4j-admin load --from=npm_ecology.dump --database=npmecology --force` to load the data into Neo4j database. This will be much faster than loading from JSON file.本数据集涵盖NPM（Node Package Manager）生态网络的相关数据集。 `npm_openrank_top100.csv` 文件包含NPM生态中排名前100的OpenRank仓库的计算结果。 `npm_ecology.json` 文件包含NPM生态开源仓库的原始网络数据，可通过执行`CALL apoc.import.json('npm_ecology.json')`命令将该网络导入Neo4j数据库。 `npm_ecology.dump` 文件由Neo4j的dump命令生成，可通过执行`bin/neo4j-admin load --from=npm_ecology.dump --database=npmecology --force`命令将数据加载至Neo4j数据库，该方式相比从JSON文件导入数据速度更快。
