Meta entities

Meta entities#

Counts bibliographic resources, agent roles (authors, publishers, editors), and venues in the dataset.

Usage#

uv run python -m oc_meta.run.count.meta_entities <SPARQL_ENDPOINT> [OPTIONS]

Options#

Option

Description

--csv

Path to CSV dump directory (required for venue counting)

--br

Count bibliographic resources (fabio:Expression)

--ar

Count agent roles (pro:author, pro:publisher, pro:editor)

--venues

Count distinct venues (requires --csv)

If no options are specified, all counts are computed.

Examples#

All counts:

uv run python -m oc_meta.run.count.meta_entities http://localhost:8890/sparql --csv /path/to/csv/dump

Only bibliographic resources and roles:

uv run python -m oc_meta.run.count.meta_entities http://localhost:8890/sparql --br --ar

Only venues:

uv run python -m oc_meta.run.count.meta_entities http://localhost:8890/sparql --venues --csv /path/to/csv/dump

How it works#

Count

Method

Bibliographic resources

SPARQL query counting fabio:Expression entities

Agent roles

SPARQL query counting pro:RoleInTime by role type

Venues

CSV dump parsing with disambiguation

Venues are counted from CSV files because the SPARQL query for venue disambiguation can exhaust memory on large datasets.

Venue disambiguation#

Venues are disambiguated based on identifiers:

  • If a venue has only an OMID (no external identifiers like ISSN/ISBN), venues with the same name are counted as one

  • If a venue has external identifiers, it’s counted by its OMID
