prov 1.0.1

A library for W3C Provenance Data Model supporting PROV-JSON import/export

A library for W3C Provenance Data Model supporting PROV-JSON import/export

• Free software: MIT license

• Documentation: http://prov.readthedocs.org.

Features

This package provides an implementation of the W3C PROV Data Model in Python. It provides in-memory classes for PROV assertions and can be serialized into PROV-JSON representation. In addition, the included prov.dot module exports 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

1.0.1 (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.
