alexandria3k 3.2.0

Efficient relational database queries over the entire Crossref abnd ORCID data sets

Alexandria3k

The alexandria3k package supplies a library and a command-line tool providing efficient relational query access to diverse publication open data sets. The largest one is the entire Crossref data set (157 GB compressed, 1 TB uncompressed). This contains publication metadata from about 134 million publications from all major international publishers with full citation data for 60 million of them. Alternatively, works can be selected from the PubMed data set (43 GB compressed, 327 GB uncompressed), which comprises more than 36 million citations for biomedical literature from MEDLINE, life science journals, and online books, with rich domain-specific metadata, such as MeSH indexing, funding, genetic, and chemical details. In addition, the Crossref and PubMed data sets can be linked with the ORCID summary data set (25 GB compressed, 435 GB uncompressed), containing about 78 million author records, the United States Patent Office issued patents (11 GB compressed, 115 GB uncompressed), containing about 5.4 million records, as well as data sets of funder bodies, journal names, open access journals, and research organizations.

The alexandria3k package installation contains all elements required to run it. It does not require the installation, configuration, and maintenance of a third party relational or graph database. It can therefore be used out-of-the-box for performing reproducible publication research on the desktop.
