ArXiv OAI-PMH arXivRaw publication metadata

This dataset contains OAI-PMH metadata for all ArXiv publications up until 2024-04-23 in the arXivRaw XML format.

The metadata has been harvested using the metha Go package v0.3.3 [1] on go1.18. Specifically, harvesting was run on a small HPC cluster using the following SLURM script. The script had to be scheduled twice due to the connection being reset by the peer (see combined-slurm.out). metha caters for these situations and is able to pick up where it left off with cumulative harvesting.

Dataset contents

This deposit of the dataset contains the following files:

• metha-output-OAI-PMH-arXivRaw-until-2024-03-24.tar.gz: an archive file containing the archive files (gzipped, *.xml.gz) produced by metha, which in turn contain the XML metadata files. The gzipped files contained in the archive are named following the pattern YYYY-MM-DD-<8-digit zero-padded 0-index file count>.xml.gz, e.g., 2024-03-24-00000001.xml.gz.
• README.md: This file, containing basic information about the dataset and deposit.
• combined-slurm.out: The combined SLURM log for the two consecutive SLURM runs that have produced the dataset. Run-specific information has been retracted.

Reproducibility

As the OAI-PMH metadata is not static but may change at any time, this dataset isn't fully reproducible. However, running the same metha version on the same go version with the same commands should yield very similar results, but will contain newer metadata.
