Managing changes to content
Why is it important to update content?
• Readers need to know that they can trust that they can use the research
• Publishers and journals are the authority on this• Not bad/negative to update works - it helps to
maintain the scholarly record - this is an important job for publishers to do
What’s the problem?
Updates are shown in different ways
Examples
It’s good to see updates in a consistent way
On HTML and PDF
Solution: Crossmark
• An embedded button for HTML and PDF that, when clicked, shows the researcher publication information that a publisher chooses to include• A great way to show users extra or updated information
about the content they’re viewing so that they can trust it• The information stays with the article and can be
accessed even away from the publisher site•Machine-readable metadata available via the Crossref
REST API
What constitutes a status update?
A change significant enough to affect the crediting or interpretation of the work
Allowed status update typesaddendum clarification correction corrigendum erratumexpression_of_concern new_edition new_version partial_retraction removalretraction withdrawal
Crossmark best practices• Comprehensive deposit of metadata
• Proper display of Crossmark button above or close to the
title of the article• Timely deposits of publication updates
How to get started
2. Create a Crossmark Policy Page
• Brief explanation of Crossmark• Links to policies on corrections and retractions• Assign a DOI for persistent linking• Deposit this page with Crossref
3. Deposit Crossmark Metadata
• DOI of the content to which Crossmark button will be added
• DOI of Crossmark policy page
• DOI of content that this deposit is updating
4. Add Crossref DOI to web and PDF
• HTML metadata<meta name=“dc.identifier” content=“10.5555/12345”>
• PDFeg. https://crossmark.crossref.org/dialog/?doi=10.5555/12345678&domain=pdf&date_stamp=2017-01-14
• Crossmark button code needs the DOI to find the metadata
