DIGITAL.CSIC metadata snapshot

Bibliographic metadata of every item in DIGITAL.CSIC, the institutional repository of the Spanish National Research Council (CSIC), harvested through its OAI-PMH interface (https://digital.csic.es/dspace-oai/request, metadataPrefix=dim).

• Snapshot date: 2026-10-14
• Records: 415,130 (deleted items excluded), in 3 Parquet file(s)
• One row per item; id is the item's Handle.

Columns

column	type	source
id	string	Handle of the item, e.g. 10261/1399
handle_uri	string	Link to the original record: dc.identifier.uri (http://hdl.handle.net/...), or built from the Handle when missing
title	string	dc.title
title_alternative	list[string]	dc.title.alternative
authors	list[string]	dc.contributor.author, in record order, as stored ("Last, First")
author_cris_ids	list[string]	DSpace-CRIS researcher-profile id of each author (authority attribute, e.g. rp13268; null when the author is not linked). Aligned with authors
editors	list[string]	dc.contributor.editor
orcids	list[string]	dc.contributor.orcid (not aligned with authors)
abstract	string	dc.description.abstract (all values, newline-joined; language tags are unreliable)
description	string	dc.description (unqualified)
subjects	list[string]	dc.subject* keywords
type	string	dc.type (e.g. artículo, comunicación de congreso)
type_coar	string	dc.type.coar COAR resource type URI
version	string	dc.type.hasVersion (e.g. Publisher's version)
language	string	dc.language.iso
date_issued	string	dc.date.issued as stored (YYYY, YYYY-MM or YYYY-MM-DD)
year	int16	Year of dc.date.issued
date_accessioned	timestamp	dc.date.accessioned: when the item entered the repository
datestamp	timestamp	OAI-PMH datestamp: last modification of the record
publisher	string	dc.publisher
citation	string	dc.identifier.citation values that are not URLs, joined with " ; "
is_part_of	string	dc.relation.ispartof
doi	string	dc.identifier.doi (normalized, no resolver prefix); falls back to a DOI found in other identifiers
issn	list[string]	dc.identifier.issn + dc.identifier.e-issn
isbn	list[string]	dc.identifier.isbn
pmid	string	dc.identifier.pmid
scopus_id	string	dc.identifier.scopus
publisher_version_url	string	dc.relation.publisherversion
license	string	dc.rights.license / dc.rights.uri: licence of the deposited work, not of this metadata
access_rights	string	dc.rights (openAccess, closedAccess, embargoedAccess, ...)
peer_reviewed	bool	From dc.description.peerreviewed
sponsorship	string	dc.description.sponsorship
funders	list[string]	dc.contributor.funder
communities	list[string]	OAI sets com_* (CSIC institutes / centres)
collections	list[string]	OAI sets col_*

Notes

• Multi-valued fields are lists; single-valued text fields keep the first value found.
• communities / collections are DSpace OAI set identifiers (e.g. com_10261_25); the set names can be fetched with verb=ListSets.
• Metadata comes from the repository as-is: language tags, author name forms and dates are not normalized beyond what is described above.

Terms of use

This dataset is released under CC BY-NC-SA 4.0, to the extent of any rights the dataset author holds in it, subject to DIGITAL.CSIC's metadata policy below, which continues to apply to the records themselves. The licence does not grant rights over third-party content in the records (e.g. abstracts, whose copyright may belong to authors or publishers).

This dataset contains metadata only (no full texts or files). Its reuse is governed by the Política de metadatos of DIGITAL.CSIC's policies:

• Non-profit purposes. DIGITAL.CSIC metadata may be reused without explicit permission for non-profit purposes. Any other use requires permission from CSIC (digital.csic@bib.csic.es).
• Link to the original record. Each reused record must mention its OAI identifier or link to the original record in DIGITAL.CSIC. Every row carries this link in handle_uri; keep it in any derived work.
• Please also cite DIGITAL.CSIC (CSIC) as the source of the metadata.
• The license column is the licence of each deposited work (often a Creative Commons licence), not a licence for its metadata. Full texts are subject to DIGITAL.CSIC's separate data policy (systematic harvesting of full texts requires explicit authorization from CSIC).

Personal data

Records contain names of researchers and, where available, ORCID iDs and DIGITAL.CSIC researcher profile ids. No e-mail addresses or other contact details are extracted into the columns above. Withdrawn or deleted items are removed when the dataset is refreshed. Requests to remove personal data from DIGITAL.CSIC go to digital.csic@bib.csic.es; please also open a discussion on this dataset so the copy here can be updated.
