My first cut with django used RDF files for data (this is ancien code,
django has changed since then):
[[[
from django.core import template_loader
from django.core.extensions import DjangoContext
from django.utils.httpwrappers import HttpResponse
from django.core import formfields
from rdflib.StringInputSource import StringInputSource
import time
from mobius.apps.contacts.models import contacts
from mobius import About
def index(request):
contacts_list = contacts.get_contacts()
contacts_list.sort(sortCodes)
date = time.ctime()
t = template_loader.get_template('contacts/index')
about = About()
c = DjangoContext(request, {
'contacts_list': contacts_list,
'date': date,
'pmr': about,
})
return HttpResponse(t.render(c))
]]]
get_contacts looked like this (rdflib with sparta):
[[[
def get_contacts():
store, schema_store = TripleStore(), TripleStore()
ds = DataStore()
ds.loadData(CONTACTS_HOME, store)
f = open(PMR_SCHEMA_LOC)
rdfxml= "".join(f.readlines())
f.close()
schema_store.parse(StringInputSource(rdfxml))
Thing = ThingFactory(store, schema_store)
gen = ds.findContactGenerators(store)
summaries = ds.loadContacts(gen, Thing, store)
return summaries
]]]
For models and admin usage your storage will need to meet the DBAPI
contract. I think it can be done, but with considerable effort. I think
I'd wonder why bother tho' - the main reason I cna think of is for the
CMS case where users can create
