README

This folder contains 4 markdown files with the SPARQL requests specialized to build the KG of land plots.

1. Requirements

  1. Create a ````cadastre``` repository in your Graph DB triplestore.
  2. Add the Ric-O ontology into dedicated named graph (or default named graph)

2. Execution

2.1 Automated execution

Have a look to the code folder.

2.2 Manual executation using documentation

The algorithm files have to be executed in the following order :

  1. Custom functions
  2. Sanity checks
  3. Update initial data
  4. Build KG

Requests in 3_Update_Initial_data.md and 4_Build_KG.md can be executed automatically using the python scripts into the python folder.

2.2.1 Initialisation

The following named graphs have to be created using the .rdf files in the data/land-registry folder of this repository.

  • Ontology
http://rdf.geohistoricaldata.org/ontology
- ontology-adresse.ttl
- ontology-cadastre.ttl
- activities.ttl
  • Plots (root plots created from maps and/or initial registers)
http://rdf.geohistoricaldata.org/rootlandmarks
- Gentilly_landmarks_initial_plots.ttl
  • Plots (plots versions created from mutation registers)
http://rdf.geohistoricaldata.org/landmarksversions
- Gentilly_landmarks_plot_mentions.ttl
- Gentilly_sources_folios.ttl
- Gentilly_sources_pages.ttl
- Gentilly_owners_cf_clas_mut.ttl
  • Other landmarks (towns, cadastral sections, streets etc.)
http://rdf.geohistoricaldata.org/otherlandmarks
- landmarks.ttl
- Gentilly_landmarks_lieu_dit.ttl
  • Sources (root sources)
http://rdf.geohistoricaldata.org/sources
- sources.ttl

3. Evaluation

SPARQL requests to answer the competency questions are in the XXX_sparql_request.md file of the /documentation/modelet_XXX folder of this repository.
