## What is the CAC Ontology?
The Crimes Against Children (CAC) Ontology Family is a community-developed evolving 
standard that provides a structured (ontology-based) specification for representing 
information commonly analyzed and exchanged by people and systems during investigations 
involving digital evidence related to crimes against children.

The power of CAC Ontology is that it provides a common language to support automated 
normalization, combination and validation of varied information sources to facilitate 
analysis and exploration of investigative questions (who, what, when, timeline, where, how, and why). 
In addition to representing tool results, CAC Ontology ensures that analysis results 
can be traced back to their source(s), keeping track of when, where and who used which 
tools to perform investigative actions on data sources.

CAC Ontology extends the Unified Cyber Ontology (UCO), the Cyber-investigation Analysis 
Standard Expression (CASE) Ontology, and the Unified Foundational Ontology (gUFO). 
This powerful combination provides specialized modules for modeling child exploitation 
investigations, operations, legal processes, reporting, offender tradecraft, victim and 
survivor related information, and digital forensics activities with high semantic precision.

## How to find entity documentation
Entity pages follow predictable URL patterns:

- Classes: https://cacontology.projectvic.org/class-<slug>.html
- Properties: https://cacontology.projectvic.org/prop-<slug>.html
- Shapes: https://cacontology.projectvic.org/shape-<slug>.html
- Concepts: https://cacontology.projectvic.org/concept-<slug>.html

The <slug> is the lowercase concatenation of the namespace prefix and local name.
Example: The property `forensics#priorityClassification` has the URL:
  https://cacontology.projectvic.org/prop-cacontology-forensicspriorityclassification.html

## Key navigation pages (recommended starting points)
- Entities A-Z: https://cacontology.projectvic.org/entities-az.html
- Classes tree: https://cacontology.projectvic.org/entities-tree-classes.html
- Properties tree: https://cacontology.projectvic.org/entities-tree-properties.html
- Shapes tree: https://cacontology.projectvic.org/entities-tree-shapes.html
- Concepts tree: https://cacontology.projectvic.org/entities-tree-concepts.html
- Statistics: https://cacontology.projectvic.org/stats.html

## Machine-friendly artifacts (recommended for bulk lookup)
- Sitemap: https://cacontology.projectvic.org/sitemap.xml
- Entity index (JSONL): https://cacontology.projectvic.org/entities.jsonl
- Merged ontology (Turtle): https://cacontology.projectvic.org/cacontology.ttl
- Merged ontology (Turtle, gzipped): https://cacontology.projectvic.org/cacontology.ttl.gz

## Entity index format (entities.jsonl)
Each line is a JSON object with:
- iri: Full IRI of the entity
- type: Class, Property, Concept, or Shape
- label: Human-readable label
- comment: Description/definition
- doc_url: Direct URL to the documentation page

## Notes
- Canonical ontology IRIs use hash fragments (e.g., .../forensics#priorityClassification).
- For human-readable docs, use the HTML pages above.
- The sitemap lists all available HTML documentation pages.
