How does SEIPID resolution work?

SEIPID Infrastructure directs a platform's Namespace Identifier (NiD) to its public registry record. A scholarly output's SEIPID resolves to its registered source or, when that source is unavailable, to its independent public metadata record.

Stable identity

How does SEIPID keep identifiers connected to their records?

SEIPID Infrastructure provides distinct persistent identities for scholarly platforms and their outputs. A Namespace Identifier (NiD) identifies a registered platform, such as a journal, repository, or publisher, and resolves to its dedicated public metadata record. A SEIPID identifies an individual scholarly work, such as an article, book, or thesis, registered under that platform and directs readers to its registered source.

As journals migrate to new platforms, repositories change domains, or publishers update their websites, authorised users can maintain registered website and source information without replacing existing identifiers. If a scholarly work's source becomes unavailable, its SEIPID continues resolving to that work's public metadata record, preserving its identity and descriptive information.

Resolution model: a NiD leads to its platform metadata record; a SEIPID leads to the registered source when available or the individual work metadata record when unavailable.
Decision path

What happens when a SEIPID is resolved?

When a reader opens a NiD or SEIPID link, SEIPID checks the identifier and its registered record. A NiD leads to the platform’s public metadata record. For a SEIPID, source availability and record status determine whether the reader reaches the scholarly source, the work’s metadata record, or an appropriate public status notice.

01
Open a NiD or SEIPID link
Not found

Unknown identifier

An unregistered identifier returns a clear not-found message.

Not found
Active + healthy

Target available

For an active SEIPID with an available source, the resolver directs readers to the work’s registered source page.

302 redirect
Active + unavailable

Fallback required

If the registered source is unavailable, the SEIPID resolves to the individual work’s independent public metadata record.

Lifecycle status

Tombstone or superseded

A withdrawn or superseded record can show a public status notice or link to an appropriate successor, preserving the context of the original registered identity.

Status-aware record
Continuity

What happens when a source link changes or becomes unavailable?

Scholarly websites, journal platforms, repository domains, and archive records can change over time. SEIPID is designed so that the identifier remains useful even when the original source moves, becomes temporarily unavailable, or needs a public metadata record instead of a direct source link.

01

Source moved

An authorised user can update the registered source URL when a work moves. Its existing SEIPID then directs readers to the updated source when available.

02

Source unavailable

If the source is not available, SEIPID can preserve discovery through a public metadata record instead of leaving the identifier as a dead link.

03

Record still identifiable

The scholarly object remains identifiable through its SEIPID, metadata, and public record relationships even when the hosting location changes.

Continuity outcomes

How does SEIPID maintain continuity when records change?

01

Platform migration

Update the platform’s registered website information and each affected work’s source links. Its NiD and existing SEIPIDs remain unchanged through a website migration.

02

Temporary or lasting outage

The metadata landing record keeps the object identifiable while the source is repaired, moved, or no longer available.

03

Withdrawn or unavailable record

If a record is withdrawn or no longer publicly available, SEIPID can preserve a public notice so the citation does not simply disappear.

04

Superseding record

An approved successor platform or separately registered related work has its own identifier. Public relationships connect it to the earlier record while preserving the original identity and its history.

Frequently Asked Questions (FAQs)

What is the difference between a Namespace ID (NiD) and a SEIPID?

A NiD identifies a registered scholarly platform and is issued after successful namespace registration. The platform has its own public record, whether or not it has registered any scholarly outputs.

A SEIPID identifies an individual scholarly output registered under that NiD, such as an article, book, thesis, or dataset. Each registered output receives its own unique, persistent SEIPID.

For example, a journal has its own NiD, while each article registered under that journal receives its own SEIPID.

What happens if the original website becomes unavailable?

When a registered output’s source becomes inaccessible, its SEIPID resolves to the corresponding public metadata record maintained by SEIPID. Readers can still identify the work, view its descriptive information, and access citation and metadata tools. SEIPID preserves the metadata record; the source platform remains responsible for the full-text files.

Can an issued SEIPID be reused for another scholarly work?

No. Once assigned, a SEIPID remains the permanent identifier for that registered work. Metadata corrections and source-link updates retain the same identifier. A different scholarly work requires its own registration and SEIPID.

What happens to a SEIPID when a work is corrected, retracted, or withdrawn?

The identifier remains associated with its registered scholarly work. Maintain accurate status information and the relevant correction, retraction, withdrawal, or relationship details so readers can understand the record. A separately published notice can receive its own SEIPID and be linked to the affected work. A status change does not justify reusing the original identifier for a different work.
