IOF Core Patterns

IOF Core patterns are currently under development. Expected release date: December, 2025

IOF Core patterns is a compendium of reusable ontology patterns for industrial data modeling built on the IOF Core vocabulary. It targets common industrial knowledge-graph scenarios and legacy-data mappings to ensure consistent, validated implementations of IOF Core. Patterns address recurring modeling needs; exemplar scenarios currently listed include: (1) change of an object’s location over time, (2) algorithm execution, and (3) assigning a measurement value with a unit.

The collection of patterns is being developed and published as a structured document (LaTeX sources plus a compiled PDF) organized as front matter, main matter, appendix, figures, and scenarios.

Development platform: The project, available at GitHub - iofoundry/IOF-Core-Pattern-v2 is Overleaf-synced. Contributors add new scenarios by creating a scenario folder with image/ and data/ subfolders, authoring a <scenario-name>.tex from the “Scenario Template”, then pushing changes from Overleaf to GitHub. Local development (e.g., diagrams, datasets, queries) happens in the synced subfolders. Direct LaTeX compilation outside Overleaf and changing the folder structure are discouraged.

Current status of development of all scenario could be found here: IOF-Core-Pattern-v2/etc/StatusBoard.csv at main · iofoundry/IOF-Core-Pattern-v2

If you want to contribute new scenario, update or review existing, please join IOF Core Pattern subgroup by sending a request to IOF Core chairs: Jim Logan, Milos Drobnjakovic, or Arkopaul Sarkar. You will be given access to the overleaf project, where the work-in-progress document can be compiled. We encourage you to read the Instruction to authors (Appendix A) for more information on patterns.
