Crossmark policy page


The journal Data & Metadata is committed to ensuring high quality standards in all its publications.

Crossmark is a multi-publisher initiative from Crossref to provide a standard way for readers to locate the current version of a piece of content. Quantum is committing to maintaining the content it publishes, and to alerting readers to changes if and when they occur.

Research doesn’t stand still: even after publication, articles can be updated with supplementary data or corrections. It’s important to know if the content being cited has been updated, corrected, or retracted - and that’s the assurance that publishers can offer readers by using Crossmark. It’s a standardized button, consistent across platforms, revealing the status of an item of content, and can display any additional metadata the member chooses. Crucially, the Crossmark button embeds in PDFs, which means that members have a way of alerting readers to changes months or even years after it’s been downloaded.

With one click, you can see if content has been updated, corrected, or retracted, and access valuable additional metadata provided by the member, such as key publication dates (submission, revision, acceptance), authors’ ORCID iDs, content type, plagiarism screening status, and information about funding, license, peer review, and location of research data.

For the purposes of Crossmark, there are two categories of updates: minor and major changes.
