The basic process for registering your content consists of these steps:
1. Construct your identifiers
When you join Crossref as a member you are issued a DOI prefix. Crossref uses the Digital Object Identifier (DOI) to provide persistence for our members’ metadata records. A DOI is a widely adapted identifier system that provides alpha-numeric identifiers that can be turned into a URL.
Your DOI prefix is unique to your organization, and allows you to create identifiers that are also unique to your organization. We give you your DOI prefix but you as the member must come up with a suffix pattern that works for your organization.
A DOI suffix follows the ‘/’ in a DOI. The specific pattern is up to you but we advise that you keep it consistent, short, and simple. Your DOI suffix can be any alphanumeric string. Limited punctuation is allowed, the approved character set for DOI suffixes is: “a-z”, “A-Z”, “0-9” and “-._;()/”. In the examples below, the Crossref-issued DOI prefix is 10.5555, everything after the ‘/’ is the DOI suffix:
||Persistent identifier (PII)
||title abbreviation, volume, and article # separated by ‘.’
||ISBN and chapter number
2. Create your registration XML
Everything submitted to the Crossref system is Crossref-formatted XML. Many members generate their own XML using our deposit schema (or have a vendor do it for them) but we also have ways to do this manually if you aren’t able to generate XML.
- Our web deposit form accepts manually entered information as well as JATS-formatted XML files.
- If you host your content on the OJS platform from PKP, there is a plugin you can use.
3. Upload your XML
Your XML can be uploaded manually using our system interface but it’s usually submitted via HTTP POST. If you are using the web form, the form uploads your registration files for you. Submissions are usually processed quickly so schedule your submissions accordingly.
All XML submitted to us must be valid to be processed, and we do some additional checking to make sure your submissions meet our standards. It’s important to address errors quickly to ensure your published links work and your metadata gets where it needs to go. You should review your submission logs to make sure your submissions are processed successfully. Submission logs are emailed to the address you include in your registration XML or enter in the web form.
5. Maintain your records
If your content moves, update your resource resolution URLs. If you need to make minor corrections to your metadata, you can do that too. You can also add other metadata if you want to collect and distribute funding data, license information, and other metadata about your content.
