Project description
The package supports the creation of PROV-O compliant provenance graphs.
The package requires Python 3.11.
Installation
You can install the package from the Python Package Index (PyPI):
pip install provo
Contents
The package implements the PROV-O starting point classes Entity, Activity and Agent as Python classes with methods to establish starting point properties between them instances of these classes.
Features
Compliance
The PROV-O classes Entity, Activity, and Agent are implemented as Python classes.
The PROV-O properties wasGeneratedBy, wasDerivedFrom, wasAttributedTo, startedAtTime, used, wasInformedBy, endedAtTime, wasAssociatedWith, and actedOnBehalfOf are implemented as instance methods of their according classes.
Attributes that are passes to these methods are type-checked to enforce compliance with PROV-O. itemName=ms-python.vscode-pylance).
Node Ids are checked for validity.
Accidental use of the same ID for different objects throws an error.
Ease of Use
The package implements full type hint support, thus enabling rich support from the IDE.
The classes Provence_Ontology_Graph, Entity, Activity, and Agent can be printed to terminal in a user-friendly, readable way with the default print() command.
for some quick testing, objects of the classes Entity, Activity, and Agent can be instantiated with auto-generated Ids (although it’s not recommended using this for production).
Interface to RDF via the rdflib package
The graph’s contents can be converted to an rdflib.Graph object.
The graph can be exported in various RDF serializations.
