With a recent version of pip:
pip3 install git+https://github.com/ProjetPP/PPP-datamodel-Python.git
With an older one:
git clone https://github.com/ProjetPP/PPP-datamodel-Python.git
cd PPP-datamodel-Python
python3 setup.py install
Use the --user
option if you want to install it only for the current user.
You can use any of the classes in the ppp_datamodel
package: Triple
,
Resource
, and Missing
. They all have a nice constructor, getters for
their attributes, and serialization methods, etc.
An example:
>>> import ppp_datamodel
>>> my_triple = ppp_datamodel.Triple(subject=ppp_datamodel.Resource(value='George Washington'), predicate=ppp_datamodel.Resource(value='birth date'), object=ppp_datamodel.Missing())
>>> print(my_triple.as_json())
{"type": "triple", "predicate": {"type": "resource", "value": "birth date"}, "subject": {"type": "resource", "value": "George Washington"}, "object": {"type": "missing"}}
>>> my_triple.predicate
<PPP node "resource" {'value': 'birth date'}>
You can also deserialize them:
>>> ppp_datamodel.AbstractNode.from_json('{"type": "resource", "value": "George Washington"}')
<PPP node "resource" {'value': 'George Washington'}>
>>> ppp_datamodel.AbstractNode.from_json('{"type": "resource", "value": "George Washington"}') == ppp_datamodel.Resource(value='George Washington')
True
For a list of their accepted attributes, see the PPP data model specification
