Introducing fise, the Open Source RESTful Semantic Engine

with 5 comments


Edit: fise is now known as the Stanbol Enhancer component of the Apache Stanbol incubating project.

As a member of the IKS european project Nuxeo contributes to the development of an Open Source software project named fise whose goal is to help bring new and trendy semantic features to CMS by giving developers a stack of reusable HTTP semantic services to build upon.

 As such concepts might be new to some readers, the first part of this blog post is presented as a Q&A.

Current semantic engines can typically:

A sample Python library for the Nuxeo Content Automation JSON-RPC API

without comments

I have created a sample Python library to illustrate the use of the
Content Automation JSON-RPC API (described here:

The project, which is only illustrative and not officially supported by
Nuxeo, lives here:

Here are the functions that have been implemented so far:

def create(self, ref, type, name=None, properties=None):
def update(self, ref, properties=None):
def setProperty(self, ref, xpath, value):
def delete(self, ref):
def getChildren(self, ref):
def getParent(self, ref):
def lock(self, ref):
def unlock(self, ref):
def move(self, ref, target, name=None):
def copy(self, ref, target, name=None):
def fetch(self, ref):
def query(self, query, language=None):
def getBlob(self, ref):
def attachBlob(self, ref, blob):

And here is a sample interactive session to illustrate its use:
