Configuration Details

`doi_author_affiliations`

Flattened author-affiliation pairs extracted from DataCite records. Each row represents one author-affiliation relationship.

Schema:

doi (string): The DOI of the work
author_idx (int): Index of the author within the work
author_name (string): Name of the author
affiliation_idx (int): Index of the affiliation for this author
affiliation (string): Raw affiliation string
affiliation_hash (string): MD5 hash of the normalized affiliation string

`enriched_records`

Original DataCite records enriched with ROR IDs where matches were found.

Schema:

doi (string): The DOI of the work
creators (list): List of creator objects with nested affiliation data including matched ROR IDs

`ror_matches`

Successful affiliation-to-ROR matches.

Schema:

affiliation (string): Raw affiliation string
affiliation_hash (string): MD5 hash of the normalized affiliation string
ror_id (string): Matched ROR ID

`ror_matches_failed`

Affiliations that could not be matched to a ROR ID.

Schema:

affiliation (string): Raw affiliation string
affiliation_hash (string): MD5 hash of the normalized affiliation string
error (string): Reason for match failure

`unique_affiliations`

List of all unique affiliation strings found in the dataset.

Schema:

affiliation (string): Raw affiliation string

`existing_assignments`

Pre-existing ROR assignments found in DataCite records. Each row represents one author-affiliation-ROR relationship that was already present in the source data.

Schema:

doi (string): The DOI of the work
author_idx (int): Index of the author within the work
author_name (string): Name of the author
affiliation (string): Raw affiliation string
ror_id (string): Pre-existing ROR ID in the DataCite record
ror_name (string): Name of the ROR organization

`existing_assignments_aggregated`

Aggregated view of pre-existing ROR assignments, grouped by affiliation string and ROR ID.

Schema:

affiliation (string): Raw affiliation string
affiliation_hash (string): MD5 hash of the normalized affiliation string
ror_id (string): Pre-existing ROR ID
ror_name (string): Name of the ROR organization
count (int): Number of occurrences of this affiliation-ROR pair

`disagreements`

Cases where the newly matched ROR ID differs from a pre-existing ROR assignment, or where multiple conflicting ROR IDs exist.

Schema (type="match"):

type (string): "match" - disagreement between new match and existing assignment
affiliation (string): Raw affiliation string
affiliation_hash (string): MD5 hash of the normalized affiliation string
existing_ror_id (string): Pre-existing ROR ID in DataCite
existing_ror_name (string): Name of existing ROR organization
existing_count (int): Occurrences of this existing assignment
matched_ror_id (string): Newly matched ROR ID
matched_ror_name (string): Name of newly matched organization

Schema (type="user"):

type (string): "user" - multiple conflicting user-submitted ROR IDs
affiliation (string): Raw affiliation string
affiliation_hash (string): MD5 hash of the normalized affiliation string
ror_ids (list): List of conflicting ROR assignments with counts
