Methodology
How NagameAlert works
NagameAlert brings together publications from AESAN, RAPNA, RASFF, Safety Gate and OECD, preserves their provenance and organises them into a common structure. It does not issue alerts or replace the originating systems and authorities.

Information journey
From the official source to NagameAlert
- 01
Official publication
An authority or official system publishes an alert, notification, recall or another communication with its own structure and scope.
- 02
Incorporation
NagameAlert retains its provenance, identity, reference and the data available in the publication.
- 03
Organisation
Selected fields are structured under common criteria to support search, filters and navigation.
- 04
Presentation
The information is shown in a consistent structure while retaining access to the official publication.
Source and processing
What belongs to each layer
The boundary between what the issuing system published and what NagameAlert processes is central to this methodology.
Source information
Official source
- Published reference and identifiers.
- Publication date and possible updates.
- Product, risk, measures, countries or batches when available.
- Text and other information available in the issuing system.
Available information depends on each system and each publication. Not every source provides the same fields or level of detail.
NagameAlert processing
NagameAlert
- Organisation of fields under a common structure.
- Classifications needed to organise the archive.
- Filters, navigation and consistent presentation.
- Geographic relationships where the available information supports them.
Organising information does not change its provenance or turn derived data into official information.
Sources and updates
Five sources. Updated independently.
Each system publishes information in its own structure and at its own pace. NagameAlert consults the sources independently to incorporate new publications and update those that change.
Availability and historical depth depend on the issuing system. An update on NagameAlert does not replace checking the official record.
How to read the records
Three distinctions that must remain clear
The systems publish different things
An alert, an information notification, a border rejection and a recall have different meanings and scopes. NagameAlert preserves the available type; it does not treat them as synonyms.
Geography expresses relationships
Origin, notifying country, distribution, affected territory and recall economy describe different relationships. For OECD, recall economy is not presented as product origin.
Absence and current status are not assumed
A missing field is not interpreted as no risk, distribution or measure. A historical record remaining online does not prove that the situation remains current.
Criteria and limits
What NagameAlert does not do
It does not invent
Missing data is not filled in through assumptions or presented as a known fact.
It does not replace
The official publication remains the primary reference for checking scope, measures and updates.
It does not misattribute
NagameAlert classifications or processing are not presented as though they came from the authority.
It does not group automatically
Similar publications are not treated as one incident by default; that relationship requires evidence and specific criteria.
Traceability
Every publication can be traced to its source
NagameAlert retains access to the official publication so that the product, risk, scope, measures and possible updates can be checked in the issuing system.
