DOI Policy

Digital Object Identifier (DOI) Policy

1. DOI assignment

Every article published in IJCIE is assigned a permanent Digital Object Identifier at the time of publication. The DOI is displayed on the article landing page and printed in the published PDF.

2. Registration agency and prefix

IJCIE registers DOIs with Crossref under the journal's own prefix 10.67513, through a sponsoring Crossref member. Crossref DOIs resolve to the article landing page on this website.

Articles published before the journal obtained its Crossref prefix were assigned DOIs through Zenodo, under the prefix 10.5281. Those DOIs remain valid, permanent and citable; they are not withdrawn, reissued or duplicated, because a published article must keep the single identifier that was printed with it. A Zenodo DOI resolves to the deposited record for that article, from which the journal version is linked. Both routes give the article a persistent, resolvable identifier maintained by a recognised registration agency.

No article carries two DOIs. If you find an IJCIE article that appears to, report it to info@ijcie.com so that the duplicate can be withdrawn.

3. What the DOI is for

The DOI is the stable, citable address of the article. It is unaffected by changes to the journal's website structure, hosting or domain. Authors and readers should always cite the DOI rather than a browser URL.

4. Citing an IJCIE article

Include the DOI as the final element of the reference, in the form doi: 10.xxxxx/xxxxxx or as a resolvable link https://doi.org/10.xxxxx/xxxxxx.

5. Metadata deposited with the DOI

The deposited record includes the title, all authors with ORCID identifiers where supplied, their affiliations, the abstract, the journal title and ISSN, volume, issue, page or article number, the publication date, the licence URL and the reference list. Depositing the reference list allows citation linking, so that works cited by IJCIE articles receive the citation.

6. Corrections, retractions and updates

Correction and retraction notices are themselves assigned DOIs and are deposited as update records linked to the original article, so that the relationship propagates to indexing services. If an error is found in deposited metadata, the record is corrected and re-deposited.

7. Persistence undertaking

IJCIE undertakes to maintain the resolution of every DOI it has registered, including in the event that the journal ceases publication, in line with the Archiving and Preservation Policy.

8. Reporting a broken DOI

A DOI that does not resolve, or resolves to the wrong article, should be reported to info@ijcie.com with the DOI and the article title. Registration records are corrected as a priority.
