Usage
=====
Simple PROV document
--------------------
.. code:: python
import prov.model as prov
import datetime
document = prov.ProvDocument()
document.set_default_namespace('http://anotherexample.org/')
document.add_namespace('ex', 'http://example.org/')
e2 = document.entity('e2', (
(prov.PROV_TYPE, "File"),
('ex:path', "/shared/crime.txt"),
('ex:creator', "Alice"),
('ex:content', "There was a lot of crime in London last month"),
))
a1 = document.activity('a1', datetime.datetime.now(), None, {prov.PROV_TYPE: "edit"})
# References can be qnames or ProvRecord objects themselves
document.wasGeneratedBy(e2, a1, None, {'ex:fct': "save"})
document.wasAssociatedWith('a1', 'ag2', None, None, {prov.PROV_ROLE: "author"})
document.agent('ag2', {prov.PROV_TYPE: 'prov:Person', 'ex:name': "Bob"})
document.get_provn() # =>
# document
# default <http://anotherexample.org/>
# prefix ex <http://example.org/>
#
# entity(e2, [prov:type="File", ex:creator="Alice",
# ex:content="There was a lot of crime in London last month",
# ex:path="/shared/crime.txt"])
# activity(a1, 2014-07-09T16:39:38.795839, -, [prov:type="edit"])
# wasGeneratedBy(e2, a1, -, [ex:fct="save"])
# wasAssociatedWith(a1, ag2, -, [prov:role="author"])
# agent(ag2, [prov:type="prov:Person", ex:name="Bob"])
# endDocument
PROV document with a bundle
---------------------------
.. code:: python
import prov.model as prov
document = prov.ProvDocument()
document.set_default_namespace('http://example.org/0/')
document.add_namespace('ex1', 'http://example.org/1/')
document.add_namespace('ex2', 'http://example.org/2/')
document.entity('e001')
bundle = document.bundle('e001')
bundle.set_default_namespace('http://example.org/2/')
bundle.entity('e001')
document.get_provn() # =>
# document
# default <http://example.org/0/>
# prefix ex2 <http://example.org/2/>
# prefix ex1 <http://example.org/1/>
#
# entity(e001)
# bundle e001
# default <http://example.org/2/>
#
# entity(e001)
# endBundle
# endDocument
document.serialize() # =>
# {"prefix": {"default": "http://example.org/0/", "ex2": "http://example.org/2/", "ex1": "http://example.org/1/"}, "bundle": {"e001": {"prefix": {"default": "http://example.org/2/"}, "entity": {"e001": {}}}}, "entity": {"e001": {}}}
