pmparser enables one to easily create and maintain a relational database of data from PubMed/MEDLINE. pmparser can download the publicly available XML files, parse them, incorporate PubMed’s regular updates, and combine the data with the NIH Open Citation Collection. PMDB, our implementation of the database, is available on Zenodo (as a PostgreSQL dump) and on Google BigQuery. For a detailed description of pmparser and PMDB, check out the article.
