Retrieve previous results when the same inputs were used

[samwaseda]

from semantikon import request_values

database_graph = get_knowledge_graph(my_workflow.run(distance=1.0, time=2.0, mass=3.0))
wf_before_execution = my_workflow.serialize_workflow()
wf_before_execution["inputs"]["distance"]["value"] = 1.0
wf_before_execution["inputs"]["time"]["value"] = 2.0
wf_before_execution["inputs"]["mass"]["value"] = 3.0
print(request_values(wf_before_execution, database_graph)["outputs"])

Output: {"kinetic_energy": {"value": 0.375}}

Pull request overview

This PR introduces a new request_values function that enables retrieval of previously computed workflow results from a knowledge graph based on matching input values. This allows workflows to check if results already exist for given inputs before re-executing computations.

Key changes:

• Added request_values function that queries an RDF knowledge graph using hash identifiers to populate workflow dictionaries with cached values
• Refactored serialize_and_convert_to_networkx to accept hash_data and remove_data parameters, moving hash computation logic from get_knowledge_graph
• Updated flowrep dependency from 0.1.7 to 0.1.8 to support the new hashing functionality
