CrossMark is a multi-editor platform from the CrossRef organization that provides a standard way to locate the official version of a document and download it. It allows authors to make corrections to their publication and clicking on the CrossMark icon will inform the reader about the current status of the particular document.

Ciencia Digital accepts 9 types of updates in accordance with Crossmark standards. The definitions of these updates are:

Addendum: Notification of additional information about an item. Addendae are published when editors decide that additional information is crucial for the reader to understand a significant portion of the published contribution.

Erratum: Notification of a major error made by the journal that affects the publication record or scientific integrity of the article, or the reputation of the authors or the journal.

Corrigendum: Notification of a major error made by the author(s) that affects the publication record or scientific integrity of the article, or the reputation of the authors or the journal

Retraction: Notification of invalid results that affect the reliability of a previously published article. The original article is marked as retracted but remains available to readers, and the retraction statement notifying readers of the invalidity of the published article is bidirectionally linked to the original published paper.

Expression of Concern: Journal editors may consider issuing an "Expression of Concern" if they have well-founded concerns and feel that readers should be aware of potentially misleading information contained in an article. However, "Expressions of Concern" should only be issued if an investigation into the issues related to the article has been inconclusive, and if there are strong indicators that the concerns are valid.

 Removal of Items: It is not advisable and is only used in exceptional circumstances for articles from previous versions that have been accepted for publication but have not yet been formally published ("press articles") but may already appear online. Such versions may contain errors, may have been accidentally submitted twice, or violate a journal's ethical publication guidelines (e.g., multiple submissions, false claims of authorship, plagiarism, fraudulent use of data, etc.). In such situations, especially in case of legal/ethical violations or false/inaccurate data that could pose a harmful risk if used, it may be decided to remove the previous version of the article from our electronic platform. Removal of the article means that the content of the article (both the HTML version and the PDF version) is deleted.

Elimination. In an extremely limited number of cases, it may be necessary to remove a published article from our online platform. This will only happen if an article is clearly defamatory, or infringes the legal rights of others, or where the article is, or we have good reason to expect it to be, the subject of a court order, or where the article may pose a serious health risk. In such circumstances, the metadata (i.e. title and author information) of the article will be retained, the text will be replaced with a screenshot or message indicating that the article has been removed for legal reasons.

New version: In cases where an article poses a serious health risk, for example, the authors of the original article may want to remove the defective original and replace it with a corrected version. In such circumstances, the above procedures for retraction will be followed with the difference that the notice of retraction of the article will contain a link to the corrected reissued article along with a history of the document.

Correction: We consider issuing a correction when: ü A small part of a reliable publication reports flawed data or turns out to be misleading, especially if this is the result of an honest mistake.ü The list of authors or contributors is incorrect (e.g., a meritorious author has been omitted or someone who does not meet the authorship criteria has been included).
