Metadata policy

This policy defines how metadata associated with all articles published in Investigación en Discapacidad is structured, identified, shared, corrected, and preserved. The purpose is to ensure maximum discoverability, interoperability with indexing services, and long-term accessibility, in alignment with the journal’s open access and preservation policies.

2. Metadata Standards and Formats

The journal uses the following metadata standards:

Standard Application
Dublin Core Basic discovery and interoperability, exposed via OAI-PMH
Schema.org (JSON-LD) Embedded metadata on HTML article pages for search engines
Crossref schema DOI registration and reference linking (the journal assigns a DOI to each article)
JATS XML Not currently produced. The journal publishes articles in HTML and PDF formats only.

3. Mandatory Metadata Fields per Article

For each published article, the journal records and exposes the following metadata:

  • Article title (original language; English translation required)

  • Author(s): full names, affiliations, and ORCID iDs (optional, but recommended)

  • Corresponding author email

  • Structured abstract (original language; English version required)

  • Keywords (3–6) (original language; English version required)

  • Persistent identifier: DOI (assigned via Crossref)

  • Publication date (YYYY-MM-DD)

  • Volume and issue number

  • Article type (e.g., original article, short communication, evidence synthesis, etc.)

  • Complete reference list

4. Persistent Identifiers (PIDs)

  • DOI: A unique DOI is assigned to every article, correction notice (erratum/corrigendum), and retraction notice.

  • ORCID: Optional for authors. Authors are encouraged to provide their ORCID to facilitate disambiguation and interoperability.

  • ISSN: Journal-level identifiers (print 2007-6452; online 2992-779X) are included in metadata records.

5. Metadata Interoperability and Harvesting

  • The journal exposes all metadata via the OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) protocol.

  • Base URL for harvesters: https://dsm.inr.gob.mx/indiscap/index.php/INDISCAP/oai

  • Metadata format supported: oai_dc (Dublin Core).

  • Harvesters with automatic access include: Google Scholar, BASE, CORE, and any repository or indexer that supports OAI-PMH. This facilitates current and future indexing.

6. License for Metadata

To maximize reuse and interoperability, all metadata associated with published articles are placed under the CC0 1.0 Universal (CC0) Public Domain Dedication. This is independent of the license for the full text of articles, which is Creative Commons Attribution 4.0 International (CC BY 4.0). This distinction ensures metadata can be freely harvested and reused without restrictions.

7. Correction, Retraction, and Versioning of Metadata

The journal follows a detailed Corrections and Retractions Policy (available at https://dsm.inr.gob.mx/indiscap/index.php/INDISCAP/CR). In relation to metadata:

  • Minor errors (e.g., typo in author name, missing affiliation) will be corrected directly in the metadata record, and a correction notice (erratum/corrigendum) will be published with its own DOI.

  • Major changes (e.g., authorship change, retraction) are handled via a formal retraction notice. The original metadata remains but is linked to the retraction notice.

  • All correction and retraction notices are prominently displayed on the journal’s website, indexed, and permanently linked to the original article metadata.

  • The original DOI remains valid and resolves to the original article, with a clear link to any correction or retraction.

8. Delivery to Preservation Systems

Full metadata (Dublin Core) is included in the journal’s digital preservation packages deposited with:

  • LOCKSS (Lots of Copies Keep Stuff Safe)

  • CLOCKSS (Controlled LOCKSS)

These systems ensure that metadata and full content remain accessible even if the journal ceases publication. The journal also participates in the PKP Preservation Network (PKP PN) as part of its OJS infrastructure.

9. Self-Archiving and Repository Deposit (Relationship with Metadata)

As stated in the journal’s Open Access Policy (https://dsm.inr.gob.mx/indiscap/index.php/INDISCAP/OA):

  • Authors are encouraged to deposit the final published version of their articles in institutional or subject-specific repositories, or on personal websites.

  • When doing so, authors should include the metadata provided by the journal (at minimum: title, authors, DOI, journal name, publication date) and acknowledge the original source.

  • Repositories harvesting metadata via OAI-PMH will automatically capture the journal’s metadata under CC0.

10. Indexing and Discovery

The journal’s metadata is structured to meet the requirements of major indexing services. Metadata completeness and quality are regularly reviewed to ensure successful indexing.

11. Author Responsibility and Verification

  • At submission, authors must provide accurate metadata (title, author names and affiliations, abstract, keywords, references). ORCID iDs are optional but strongly encouraged.

  • During proof review, authors verify the final metadata before publication.

  • Requests for post-publication metadata corrections follow section 7 of this policy.
