A library for W3C Provenance Data Model supporting PROV-JSON and PROV-XML import/export
Free software: MIT license
Documentation: http://prov.readthedocs.org.
Features
An implementation of the W3C PROV Data Model in Python.
In-memory classes for PROV assertions, which can then be output as PROV-N
Serialization and deserializtion support: PROV-JSON and PROV-XML.
Exporting PROV documents into various graphical formats (e.g. PDF, PNG, SVG).
Uses
This package is used extensively by ProvStore, a respository for provenance documents.
History
1.2.0 (2014-12-19)
Added: prov.graph.prov_to_graph to convert a ProvDocument to a MultiDiGraph
Added: PROV-N serializer
Fixed: None values for empty formal attributes in PROV-N output (issue #60)
Fixed: PROV-N representation for xsd:dateTime (issue #58)
Fixed: Unintended merging of Identifier and QualifiedName values
Fixed: Cloning the records when creating a new document from them
Fixed: incorrect SoftwareAgent records in XML serialization
1.1.0 (2014-08-21)
Added: Support for PROV-XML serialization and deserialization
A ProvRecord instance can now be used as the value of an attributes
Added: convenient assertions methods for ProvEntity, ProvActivity, and ProvAgent
Added: ProvDocument.update() and ProvBundle.update()
Fixed: Handling default namespaces of bundles when flattened
1.0.1 (2014-08-18)
Added: Default namespace inheritance for bundles
Fixed: NamespaceManager.valid_qualified_name did not support prov.model.XSDQName
Added: Convenience prov.read method with a lazy format detection
Added: Convenience plot method on the ProvBundle class (requiring matplotlib).
Changed: The previous add_record() method renamed to new_record()
Added: The new add_record() function which takes one argument, a ProvRecord, has been added
Fixed: Document flattening
Added: hash function added to ProvRecord (at risk: to be removed as ProvRecord is expected to be mutable)
Added: extra_attributes added to mirror existing formal_attributes
1.0.0 (2014-07-15)
The underlying data model has been rewritten and is incompatible with pre-1.0 versions.
References to PROV elements (i.e. entities, activities, agents) in relation records are now QualifiedName instances.
A document or bundle can have multiple records with the same identifier.
PROV-JSON serializer and deserializer are now separated from the data model.
Many tests added, including round-trip PROV-JSON encoding/decoding.
