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 Creative Commons Namensnennung- Keine kommerzielle Nutzung- Page 7 of 14 Keine Bearbeitung 3.0 Österreich Lizenz

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.● code at http://github.com/collective/fise.client● integration buildout at http://github.com/collective/fise-buildout Creative Commons Namensnennung- Keine kommerzielle Nutzung- Page 10 of 14 Keine Bearbeitung 3.0 Österreich Lizenz

Plone IntegrationWork 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 Creative Commons Namensnennung- Keine kommerzielle Nutzung- Page 12 of 14 Keine Bearbeitung 3.0 Österreich Lizenz
