Access the P-LOD Triplestore

Install using python3 -m pip install git+https://github.com/p-lod/plodlib

From command line try: python3 -m plodlib --method depicts_concepts pompeii

This will show a list of all the concepts that the Pompeii Artistic Landscape Project has recorded at Pompeii.

All of this is in early stages!

plodlib can cache SPARQL query results on disk to speed up repeat lookups (useful for classroom / demo workloads where the same URLs are hit many times in a short window). Caching is off by default — importing the library creates no files. Enable it explicitly at startup:

import plodlib
plodlib.enable_cache()                # defaults: ./cache, 100 MB, 30-minute TTL
# or, with explicit args:
plodlib.enable_cache(directory='/var/lib/plod/cache', size_mb=200, ttl_sec=1800)

Backed by diskcache (SQLite, multi-process safe — gunicorn workers can share the same cache directory). Disable with plodlib.disable_cache(). Invalidation on a triplestore re-ingest: either wait out the TTL or rm -rf the cache dir.
