• 309 degree programs
• 10,000+ teaching modules
• Semantic metadata on instructors, curricula, and disciplinary sectors
• Released under CC-BY 4.0
• Usable in Neo4j and CSV formats

Getting Started (Neo4J)

1. Clone the repository:

git clone https://github.com/umbfer/SapientIAGraph.git
cd SapientIAGraph

2. Restore the Neo4j dump:

Make sure your Neo4j instance is stopped before restoring the database.

neo4j stop
neo4j-admin restore --from=data/SapientIAGraph_neo4j.dump --database=siag.db --force
neo4j start

If you're using Neo4j Desktop, place the dump in the import folder of your project and use the "Restore from Dump" option in the interface.

3. Set the active database in neo4j.conf (if needed):

dbms.default_database=siag.db

4. Open Neo4j Browser at http://localhost:7474 and start exploring.

5. Try the example queries in docs/example_queries.md
