europepmc-bulk 0.1.1

Bulk, parallel, resumable harvester for the Europe PMC corpus

europepmc-bulk

Bulk, parallel, resumable harvester for the Europe PMC corpus.

europepmc-bulk complements the existing pyeuropepmc package — pyeuropepmc is great for ad-hoc search and per-article analysis; europepmc-bulk is built for harvesting the entire 40M-article corpus with cursor pagination, atomic file writes, resume state, and threaded parallelism.

Features

• REST search with cursor-mark pagination
• Bulk FTP/HTTPS downloads of full-text archives, text-mined CSVs, ID mappings
• Annotations API batch collection
• OAI-PMH incremental updates
• JATS XML parsing
• Atomic file writes for crash safety
• Persistent resume state (interrupt and resume any harvest)
• Token-bucket rate limiter (default 10 req/s, configurable)
• Threaded parallel harvest with shared rate limiter
• Optional async HTTP client (pip install "europepmc-bulk[async]")
• Click CLI mirror of the Python API

Install

pip install europepmc-bulk
# or with async client
pip install "europepmc-bulk[async]"

Quick start

from europepmc_bulk import Config, AbstractHarvester
