Scholarship that remains findable
To support a globally accessible scholarly ecosystem in which scholarly platforms and their outputs remain consistently identifiable, citable, and discoverable over time.
About the SEIPID Infrastructure
A persistent identifier infrastructure built to keep scholarly platforms and their outputs identifiable, citable, and discoverable across changing digital environments.
The platform
A stable identity layer for scholarly platforms and outputs
SEIPID is the Scholarly Entity International Persistent Identifier Infrastructure, governed and operated by Xpertno Research Center (XRC). It issues persistent identifiers (SEIPIDs) to all types of scholarly outputs and Namespace Identifiers (NiDs) to registered scholarly platforms.
After successful namespace registration, a journal, repository, archive, publisher, scholarly press, or conference organisation receives its own persistent NiD and dedicated public metadata record, whether or not it has registered any scholarly outputs. Each scholarly output registered under that platform receives its own unique SEIPID and independent metadata record. These records help preserve scholarly identity when websites change, platforms migrate, or original source locations become unavailable.
Beyond resolution, SEIPID tracks the citations between registered works — building a public cited-by view at article, journal, and author level, with author totals carried through to XPENID profiles.
Purpose
Vision & Mission
SEIPID is designed around the practical needs of a scholarly record that continues to move across platforms, institutions, and publishing systems.
Persistence through structured metadata
To provide cost-efficient persistent identifiers linked to stable metadata landing records, supporting long-term continuity and discovery across evolving digital platforms.
Continuity
What the infrastructure is built to protect
Stable identity
Persistent NiDs identify registered scholarly platforms, while SEIPIDs identify individual scholarly outputs, giving both a durable reference independent of changing web locations.
Metadata resolution
A NiD resolves to the platform's public metadata record. A SEIPID resolves to the work's registered source, or to its public metadata record when that source is unavailable.
Citation continuity
The persistent record helps citations remain meaningful when domains, journal platforms, and source URLs change.
Stewardship
Governed and maintained by XRC
SEIPID is developed, governed, operated, and maintained by Xpertno Research Center (XRC). XRC provides the institutional stewardship behind registry policy, technical operations, metadata management, and long-term platform development.
Designed for modern scholarly communication
Digital-First Scholarly Infrastructure
Scholarly communication has moved beyond the limits of print. Research now travels across journal platforms, repositories, databases, institutional websites, author profiles, and AI-driven discovery systems. In this changing environment, the identity of a scholarly platform or work should not depend on one website, one file location, or one publishing format.
SEIPID is built as a digital-first identification infrastructure for scholarly platforms and their outputs. It creates metadata-linked records that help scholarly entities remain discoverable, traceable, and contextually connected across different digital environments. The system can support journal articles, books, chapters, theses, datasets, reports, software, proceedings, and other eligible scholarly outputs.
Rather than replacing publishers, repositories, or archives, SEIPID works as a persistent identification layer around the scholarly record. The full text remains under the control of its publisher, repository, or rights holder, while SEIPID strengthens the identity, metadata, continuity, and discoverability of the research object.
