Title: Ontology Manager
-The Stanbol Ontology Manager provides a controlled environment for managing
ontologies, ontology networks and user sessions for semantic data modeled after
them. It provides full access to ontologies stored into the Stanbol persistence
layer.
+The Stanbol Ontology Manager provides a __controlled environment__ for
managing ontologies, __ontology networks__ and user sessions for semantic data
modeled after them. It provides full access to ontologies stored into the
Stanbol persistence layer. Managing an ontology network means that you can
activate or deactivate parts of a complex model from time to time, so that your
data can be viewed and classified under different "logical lenses".
This is especially useful in [Reasoning](reasoners.html) operations.
+
+## Usage Scenarios
+
+### User networks
+
+In your CMS, you might be interested in figuring out the trust and
acquaintance network of its users. This can be a combination of the _asserted_
network (i.e. what other users are included in the contact or friend list of a
given user) with the _inferred_ network (e.g. exclude those who are in the
contact list of a blacklisted user). The latter can be derived from the user
activities over the user-generated content of your CMS (e.g. blogs posts, forum
posts, reviews, tweets, ratings).
+
+Both types of networks can be modelled as ontologies. Models can be build on
the _class_ level, or _TBox_ (e.g. everyone who is an Administrator is also a
User, and collaborates with every other Administrator of the same system) and
on the _instance_ level, or _ABox_ (e.g. John is a friend of Mary, who created
blog post bp345263 on 3/10/2012 at 15:10). These models can all be stored using
the Store facility of the Ontology Manager.
+
+Using a [reasoner](reasoners.html) you can classify all the knowledge loaded
on Stanbol, but this can be a time-consuming process due to classifying
knowledge we are not interested in for this task.
[OntoNet](ontologymanager/ontonet.html) allows you to select only the
"interesting" parts of your knowledge base. For example, if the
knowledge contains classifications of animal species, you may want to
deactivate that model when reasoning on user networks. Likewise, you may want
to consider the user profiles _today_, rather than who was a user's friend five
years ago. Therefore, on the instance level you will exclude the profile
history and only consider today's snapshot.

+A Web __Ontology__ in computer and information science is a shareable
conceptual model of a part of the world <a href="#ref1">[1]</a>. This model
describes concepts terms of their characteristics and their relations with
other concepts.

- Store - create, read, update and delete operations on single
ontologies stored in Stanbol. These operations can be performed on entities,
axioms, and whole ontologies.
