The document discusses integrating the FISE semantic framework with Python and Plone. It introduces FISE, Python, Zope, and Plone and describes creating a Python API for FISE that hides its HTTP aspects. The API uses libraries like rdflib and restkit. Code is hosted on GitHub. Integrating FISE indexing and querying with Plone collections is discussed. A demo of the integration is presented.

7. FISE Python API
Goals
● offer a pythonic API to all FISE features exposed
by its RESTFul API
● hide as much as possible the HTTP aspect
● use a widely used, well tested and scaleable
foss-library for RESTFul http connections
● full test coverage with Python doctests
● provide an zc.buildout based installation which
includes FISE itself and the tests

8. FISE Python-API
fise.client
Wanna smell code? Doctest style:
FISE „engines“
1 >>> from fise.client import FISE
2 >>> fise = FISE('http://localhost:8080/')
3 >>> somedoc = u"This is an example text."
4 >>> fise.engines(somedoc)
5 '<rdf:RDF...</rdf:RDF>n'
6 >>> fise.engines(somedoc, format='rdfjson')
7 '{"...}'
8 >>> fise.engines(somedoc, parsed=True)
9 <Graph identifier=... (<class 'rdflib.Graph.Graph'>)>

9. FISE Python-API
fise.client
FISE „store“
1 >>> generated_id = fise.store.add(somedoc)
2 >>> fise.store[existing_id] = somedoc
3 >>> fise.store[generated_id] == somedoc
4 True
5 >>> fise.store.metadata(existing_id)
6 '<rdf:RDF...</rdf:RDF>n'
7 >>> fise.store.metadata(existing_id, parsed=True)
8 <Graph identifie... (<class 'rdflib.Graph.Graph'>)>
9 >>> fise.store.page(generated_id)
10 '<html>...</html>'

10. FISE Python API
Implementation Details
● uses restkit as rest library
● uses rdflib to transform results to Python object
graphs,
● uses SuRF library (on top of rdflib) for Sparql
queries.

12. Plone Integration
Work done so far:
● „indexing“ in FISE after creation and changes of
content-objects.
Whats missing?
● query facility
– Zope plugin index to FISE sparql endpoint
– Integration with Collections
● passing the site-structure and DC to FISE.
● asynchronous processing
