# DIGITAL.CSIC metadata snapshot

Bibliographic metadata of every item in [DIGITAL.CSIC](https://digital.csic.es), 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](https://creativecommons.org/licenses/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](https://digital.csic.es/dc/politicas/):

- **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.
