Creating Triples

Single Triple

[2]
Created triple with ID: e03e6364-7397-4656-9ea0-6f6ac4a3b4e1
  Albert Einstein ā†’ born_in ā†’ Ulm, Germany

Batch Triple Creation

[3]
āœ… Created 8 triples!
Triple IDs: ['026e49a8-a061-4974-aa84-35e12254af79', '11689681-bc94-41b3-88ba-ddb9009fa4f5', '9f0c3992-9d56-4d78-a783-35858f3dc33b']...

Querying Triples

Basic Query with Pagination

[4]
šŸ“Š Retrieved 10 triples:

Filtering Triples Locally

After querying, you can filter triples client-side:

[6]
šŸ”¬ Triples about Einstein (7):
  Albert Einstein ā†’ won ā†’ Nobel Prize in Physics
  Albert Einstein ā†’ is_a ā†’ physicist
  Albert Einstein ā†’ worked_at ā†’ Princeton University
  Albert Einstein ā†’ died_year ā†’ 1955
  Albert Einstein ā†’ born_year ā†’ 1879
  Albert Einstein ā†’ developed ā†’ Theory of Relativity
  Albert Einstein ā†’ born_in ā†’ Ulm, Germany

šŸ“‚ 'is_a' relationships (14):
  Albert Einstein is_a physicist
  Theory of Relativity is_a scientific_theory
  JavaScript is_a programming_language
  Guido van Rossum is_a software_engineer
  Python is_a programming_language

Updating Triples

Update an existing triple by its ID:

[7]
Created triple with ID: 9524257b-fe17-41c5-986c-406167f0069b
āœ… Updated triple:
  Mars ā†’ distance_from_sun ā†’ 227.9 million km

Deleting Triples

Delete Single Triple

[8]
Created triple with ID: 6b4bc906-3daa-469a-a644-ef33f15b2c99
āœ… Deleted triple: 6b4bc906-3daa-469a-a644-ef33f15b2c99

Delete Multiple Triples

Created 3 temporary triples
āœ… Deleted 3 triples

Working with Data Frames

Convert triples to pandas DataFrame for analysis:
