20. Crossref DOI display guidelines
• Always be displayed as a full URL link
• An example of the best practice in displaying a Crossref DOI link is:
https://doi.org/10.1629/22161
• Old format was http://dx.doi.org/
21. Your landing page
• A full bibliographic citation so that the user can verify they have been
delivered to the correct item
• The DOI displayed as a URL, per display guidelines
• A way to access full text: access to full text is completely controlled
by the publisher but the landing page must be accessible to
everyone.
23. more metadata
reference lists, funding data, ORCIDs, license data, clinical trial numbers,
errata, retractions, updates and more through our Crossmark service,
JATS-formatted abstracts, relationships between items…
24. Ways to register
content
Upload XML file (https://doi.crossref.org)
The manual web deposit form (https://apps.crossref.org/webdeposit)
OJS Crossref plugin (https://docs.pkp.sfu.ca/crossref-ojs-
manual/en/config)
Metadata Manager (https://www.crossref.org/metadatamanager/)
25. Create XML
Crossref Schema
Metadata deposit schema: for everything
Metadata deposit schema 4.4.2 (documentation)
Resource schema: for adding most non-bibliographic metadata to existing
records
doi_resources4.3.6.xsd (documentation)
30. OJS/Crossref integrations
As of OJS 3.1.2
• Reference linking and depositing
• Funding metadata
• iThenticate plugin
https://docs.pkp.sfu.ca/crossref-ojs-manual/en/
33. Please note...
The plugin will deposit DOIs on publication, but your DOIs
will still take time to be processed. It is not immediate.
The plugin does not automatically update DOIs if metadata
changes. That has to be done manually.
If a DOI deposit has failed, you can click on the failure link
for a report
more info at: PKP's Community forum https://forum.pkp.sfu.ca/ and
PKP documentation https://docs.pkp.sfu.ca
45. Keeping metadata up to date
• Correct metadata errors
• Add more metadata to an existing record
• Update URLs
46. What if something changes
• Change/correction to the metadata
• E.g. author’s name is entered incorrectly
• Change to the URL
• E.g. your publication moves to another site or
you transfer your content to another member
Do not re-assign another DOI
There is never a charge to update DOIs
52. Correcting your metadata if you have already
deposited it
• Resubmit metadata via XML - overwriting the old record
with new information
• Redeposit via the Web Deposit Form
• Edit the metadata record in Metadata Manager
58. Reports
• Our Conflict and Resolution reports can help you
identify existing metadata errors. You can fix these
with no charge.
• The Conflict report includes information about
conflicts that have been created by members when
two (or more) metadata records share similar or
identical metadata.
59. Resolution reports
• Resolution reports are sent out via email at the beginning of
each month
• When a researcher clicks on a DOI link for an article, that
counts as one DOI resolution. No information is captured about
who the user is or where they are coming from.
• A separate report is generated for each DOI prefix.
• If you have a high number of failures - don’t panic, but do pay
attention! Sometimes this can user error in typing or cutting-
and-pasting DOIs or the DOI has been distributed but not
deposited.
60. Why reports are important
• Make sure your content is properly registered
• See how content is being used
• Catch any errors
Make sure the right person in your organization gets
them! If not, please write to [email protected].
67. A tool to use where:
You can see what metadata you are registering with
Crossref
You can track progress of your metadata
You’re able to see how you measure up to other members
What are they?
68. Why did we create them?
Members are not always aware of what metadata they’re
sending to Crossref
Members can see what’s missing and can fix the gaps
And can track progress of their metadata in an easy and
user-friendly way
71. Access the reports at https://www.crossref.org/members/prep/
and you can find documentation to help on our website.
73. ● Greater discovery of your content

88. Members are provided with access to Turnitin’s powerful text comparison
tool, iThenticate. This allows them to compare submitted manuscripts against
the largest comparison database of scientific, technical and medical content in
the world.
Similarity Check members contribute their own published content into
iThenticate’s database of full-text literature.
Similarity Check
89. What is iThenticate?
Turnitin’s plagiarism detection software
• Text-based screening
• Compares against content from
○ 1 billion web pages,
○ 60 million items from Crossref members
○ 105 million items from other content partners such as Pearson,
Cengage, EBSCOHost etc.
90. How the service works
• Upload a document to iThenticate
• A similarity report is produced
• Compare side-by-side
• Editor makes a decision about
whether the similarity detected is
legitimate or if further investigation is
required
• When members publish new content,
they provide a link to their full-text
which Turnitin use to index the item
and add it into their database
92. What issues are publishers looking for?
• Poor, missing, or incomplete references (can be fixed)
• Self-plagiarism/text recycling (can be fixed)
• Unattributed use of parts of another person’s work
• Submitting another person’s work as your own
• Is the author attempting to mislead/misrepresent?
94. How much does it cost?
• Annual administrative fee equal to 20% of your Crossref membership fee, paid to Crossref along with your annual
membership fee.
• Each document run through Similarity Check is charged at a per-document-checking fee. There is a separate invoice
for Similarity Check document checking fees.
• If you work with a sponsor, they’ll receive the invoices for your use of the service.
• Invoices for the per document checking fees Similarity Check service will be sent, from Crossref, in January (for the
previous year). You can check how many documents you’ve checked in the Reports section in iThenticate.
95. Crossmark is a great way to
show users extra or updated
information about the
content they’re viewing so
that they can trust it
96. Crossmark
• An embedded button for HTML and PDF that, when clicked,
tells the reader if any changes have been made since
publication
• 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
100. Deposit additional metadata
• Funding data
• License information
• ORCID iDs
• Clinical trial numbers
• Any additional custom metadata
• Publication history
• Similarity Check deposited
• etc.
102. Uptake
• Over 1000 publishers depositing Crossmark metadata
• 148,000 updates to content
• Majority corrections or errata
• ~5,000 of the updates are retractions
103. How to participate
1. Create a Crossmark policy page and assign it a DOI.
2. Deposit Crossmark metadata as part of your regular
metadata deposits.
a. This can also be deposited as stand-alone data for
backfile content
3. Add the Crossmark button to your articles (web and
PDF)
From January 2020 we have removed the fees for this
service.
107. Make Data Count
Since 2014, the Make Data Count (MDC) initiative has focused on building the social and
technical infrastructure for the development of research data metrics. With funding from the
National Science Foundation, Gordon and Betty Moore Foundation, and Alfred P. Sloan
Foundation, the initiative has transformed from a research project with an aim to understand
what researchers value about their data, to an infrastructure development project, and now into
a full-fledged adoption initiative.
Additional funding from the Sloan Foundation to focus on widespread adoption of standardized
data usage and data citation practices, the building blocks for open research data metrics.
108. Make Data Count: aims
1. Increased adoption of standardized data usage across repositories through
enhanced processing and reporting services
2. Increased implementations of proper data citation practices at
publishers by working in conjunction with publisher advocacy groups
and societies
3. Promotion of bibliometrics qualitative and quantitative studies around data
usage and citation behaviors
