Changelog

Version 0.3.x

Version 0.3.1

Version 0.3

  • Changed ``provdb.create_*`` to ``provdb.save_*`` because we can’t guarantee that the db-adapter actual create a new node, document, relation. Maybe the adapter merges your properties into existing data, behavior is still the same.
  • Renamed files provDb.py into prov_db.py
  • Enhanced the prov:Mention support. If you create a bundle link (prov:Mention) the destination bundle entity will be automatically created. For example: ```python

from prov.tests.examples import bundles2

doc = bundles2() bundle = list(doc.get_records()).pop() #I know, the get_record function return a set, so it can happen that you get the wrong bundle here (alice:bundle5 is correct) prov_api.save_bundle(bundle) ```

  • Add ability to save relations between elements that doesn’t exist. For example, on a empty database:
doc = ProvDocument()
relation = doc.wasGeneratedBy("ex:Entity", "ex:Activity")

#Works now fine. The ex:entity and ex:Activity elements will be created automatically
provapi.save_relation(relation)
  • Removed node type “Unknown” for relations with unknown nodes. (The prov-db-adapter now detects which type the relation implicitly mean.
doc = ProvDocument()
relation = doc.wasGeneratedBy("ex:Entity", -)

# Creates a Activity with a random identifier as destions for the relation
provapi.save_relation(relation)
  • Introduced new methods

prov_db.save_relation(prov_relation)

doc = ProvDocument()

activity    = doc.activity("ex:yourActivity")
entity      = doc.entity("ex:yourEntity")
wasGeneratedBy = entity.wasGeneratedBy("ex:yourAgent")

# Save the elements
rel_id = prov_db.save_relation(wasGeneratedBy)

prov_db.save_element(prov_element, [bundle_id])

doc = ProvDocument()

agent       = doc.agent("ex:yourAgent")
activity    = doc.activity("ex:yourActivity")
entity      = doc.entity("ex:yourEntity")

# Save the elements
agent_id = prov_db.save_element(agent)
activity_id = prov_db.save_element(activity)
entity_id = prov_db.save_element(entity)

prov_db.get_element(identifier)

doc = ProvDocument()

identifier = QualifiedName(doc, "ex:yourAgent")

prov_element = prov_db.get_element(identifier)

prov_db.save_record(prov_record, [bundle_id])

doc = ProvDocument()

agent       = doc.agent("ex:Alice")
ass_rel     = doc.association("ex:Alice", "ex:Bob")

# Save the elements
agent_id = prov_db.save_record(agent)
relation_id = prov_db.save_record(ass_rel)

prov_api.save_bundle(prov_bundle)

doc = ProvDocument()

bundle = doc.bundle("ex:bundle1")
# Save the bundle
prov_db.save_bundle(bundle)

prov_db.get_elements([ProvCLS])

from prov.model import ProvEntity, ProvAgent, ProvActivity

document_with_all_entities = prov_db.get_elements(ProvEntity)
document_with_all_agents = prov_db.get_elements(ProvAgent)
document_with_all_activities = prov_db.get_elements(ProvActivity)

print(document_with_all_entities)
print(document_with_all_agents)
print(document_with_all_activities)

prov_db.get_bundle(identifier)

doc = ProvDocument()
bundle_name = doc.valid_qualified_name("ex:YourBundleName")
# get the bundle
prov_bundle = prov_db.get_bundle(bundle_name)
doc.add_bundle(prov_bundle)
