Model your domain
Define any relationship your domain needs, with your own types, participant roles and properties.
Connected information. One environment.
Your information.
Connected.
A unified web database for the subjects, relationships and workflows that matter to you.
Model your domain, rooted in Topic Maps. Work with connected information in one environment and build dedicated websites on that model.

The platform
One environment.
Your data and workflows.
AToM⁴ brings records, relationships, searches and task views into one web environment. Its ontology defines your domain, providing a shared model for your team's work and dedicated websites.
Work in context
Move from a record to related information and see how the pieces belong together.
Find what matters
Use searches, filters and structured queries to build useful views of your data.
Build dedicated websites
Create websites and portals for different audiences from the connected information your team manages in AToM.
Built-in taxonomies and hierarchies
Classify information from several perspectives and preserve the structure of complex publications.
Group Tree
Built-in multidimensional taxonomies
Classify the same record from different perspectives, with hierarchical categories and single or multiple choices within each branch.
One publication
- Subject
- Health
- Geography
- Europe
- Document type
- Report
Hierarchy
Hierarchies for large publications
Keep publications organised in ordered trees with thousands of branches. Volumes, chapters and sections remain individual records you can open and work with.

Projects built on AToM
Different domains.
A shared foundation.
From specialist workspaces to public websites, projects across the AToM platform family put connected information to work.

CATOOL
Manage metadata once,
at the right level.
A connected workspace for multilingual publications. Common metadata belongs to the Work, language-specific information to the Expression, and edition details to the Manifestation.

Zákony pro lidi
Connected legal information, made for people.
Built on AToM, the Czech Republic's most visited legal portal connects legislation and case law for professionals and the wider public.
- Preserve structure. Legal texts are assembled from smaller parts in the database into readable documents.
- Reveal context. Connect legislation and international treaties with related court decisions.
- Open access. Read current legislation free of charge, with advanced tools available through Zákony pro lidi Plus.
A dedicated public website turns a structured, connected information model into a service people use in everyday life.
EU document workflows
Indexing and Legal Analysis
From EU documents to connected, checked metadata.
AToM brings document records, controlled vocabularies and legal relationships into the same workspace as the tasks used to process them.
- Describe consistently. EuroVoc and EU authority tables support classification and metadata entry.
- Keep context. Link related legal documents and search through their relationships.
- Coordinate the team. Shared task views, deadlines and automatic checks support the production workflow.
Analysts focus on expert work while AToM handles routine checks and prepares structured delivery outputs.
Discuss document workflowsThe working environment
Built for the pace
of real work.
Find a record, follow its relationships and work at the right level. CATOOL shows how AToM⁴ brings specialist cataloguing tasks into one connected workspace.
Keep context visible. Related records remain part of the same working picture.
Use a shared vocabulary. Multilingual labels and concept relationships support consistent description.
Inspect the output. See how the publication metadata comes together in a MARC preview.
Rooted in Topic Maps
Meaning is part
of the model.
AToM stands for AION Topic Maps. Information becomes more useful when you can see what it is about, how subjects relate, and where to find the resources that describe them.
AToM⁴ builds on the principles of Topic Maps: subjects, associations and information resources. Your ontology defines the relationship types, participant roles and properties that give these connections meaning.
A closer look at the standard
The ISO/IEC 13250 family defines Topic Maps. Its data model describes topics, associations and occurrences, and how topic maps are interpreted and merged. AToM has developed a practical web database model from these roots.
ISO/IEC 13250-2 data modelSubjects
The people, publications, concepts or other things your information is about.
Relationships
Connections you define, with explicit participant roles and properties on the relationships themselves.
Information resources
The descriptions and sources that tell you more about a subject.
The platform’s evolution
Three generations.
One connected idea.
From a web database with Topic Maps roots to today’s connected workspaces, AToM builds on years of practical use.
Main periods of development and use
2010–2015
AToM2
2D · Information on a plane
Establishing a universal web database, rooted in Topic Maps, for modelling subjects, properties and relationships.
2016–2023
AToM3
3D · Relationships with depth
Richer properties on associations give relationships their own detail, as the shared environment develops across legal information, indexing and knowledge projects.
2024–today
AToM4
4D · Information in motion
Building on AToM³ with a modern web interface and specialist workspaces, including CATOOL for multilingual publication metadata.
If the superscripts were dimensions, AToM² would lay information out, AToM³ would give relationships depth, and AToM⁴ would set the whole picture in motion. No special glasses required.
