How SEIPID Works?
A SEIPID is a unique, persistent, human-readable identifier expressed as a structured string. It is designed to identify a scholarly entity itself—not its location—and remains stable even if websites, domains, or storage systems change.
A SEIPID is composed of multiple meaningful segments ([PREFIX]:[NAMESPACE]:[SUFFIX]) separated by colons (:). Each segment represents a specific level of identification, such as the registering entity, publication context, or item type. This clear separation ensures readability, consistency, and long-term traceability across different scholarly outputs. Each journal, publisher, or university is assigned a unique prefix and namespace (abbreviation) at registration, ensuring global uniqueness without requiring changes to the underlying system.
A typical journal article SEIPID, for example 000:xijir:v1n1a1, consists of a unique registration number (000), a journal or publisher abbreviation (xijir), followed by structured indicators that identify the scholarly item.
The same prefix–namespace structure applies to other scholarly outputs. Books, theses, conference materials, and institutional records use controlled indicators appropriate to their content type (for example, 045:oxpress:b1e1c0 for a book or 021:seinu:phd1 for a doctoral dissertation). This flexibility allows SEIPID to support diverse scholarly materials without altering its core structure.
Regardless of content type, a SEIPID always resolves through the SEIPID resolver (https://seipid.com/000:xijir:v1n1a1) to a public registry record. This record displays verified metadata, registry status, and official links, allowing information to be updated over time without breaking citations or references.
Digging the SEIPID String
A SEIPID follows a consistent, layered structure that makes scholarly identifiers both machine-resolvable and human-readable.
SEIPID Workflow
SEIPID follows a structured yet flexible workflow that supports both small and established journals. The system is designed to balance automation with human oversight, allowing journals and publishers to register, manage metadata, and generate persistent identifiers with minimal friction while maintaining registry integrity.
From identity verification to identifier generation and ongoing compliance monitoring, each step is documented, auditable, and aligned with long-term scholarly publishing standards.
Why SEIPID?
Because scholarly records must remain accessible, trustworthy, and citable even when platforms change, journals migrate, or websites disappear.
Why not only DOI?
DOI plays a critical role in scholarly publishing. However, many journals and institutions face challenges related to cost, onboarding complexity, scope limitations, and long-term administrative overhead. SEIPID is designed as a complementary, institution-friendly infrastructure that lowers barriers without compromising persistence or accountability.
