data folder

This folder stores files used to build knowledge graph. It is split in two repositories:

• addresses folder contains csv and geojson files which describe addresses and streets from different sources at different times (RDF resources are built during process) ;
• land-registry has RDF resources for the specific case of the plots from the Napoleonic land registry.

⚠️ To get more information about their content, please read their readme : addresses and land-registry

ontology folder

Two files describe the ontology: ontology-addresses.ttl is the core part of the ontology and describe landmarks and addresses whereas ontology-land-registry.ttl integrates specific modules used to describe the Napoleonic land registry documents and landmarks.

Ontology documentation is divided into as many parts as there are modelets:

• addresses with its extension for land registry landmarks ;
• land_registry_documents_use ;
• sources ;
• taxpayers ;
• temporal_evolution.

Each modelet documentation has 3 or 4 files:

• {modelet_name}_scenario.md: the natural-language argument describing the sub-problem to be addressed ;
• {modelet_name}_glossary.md: glossary which defines the main terms involved ;
• {modelet_name}_competency_questions.md: set of informal competence questions (in natural language) which represent the questions to be answered by the knowledge base ;
• {modelet_name}_sparql_queries.md: it translates informal competence questions into SPARQL queries.

scripts folder

This folder contains code to build knowledge graphs. Since addresses and land plots have their own specificities, each one has a folder in which its code allow KG construction.
