========
* **Environment**
Environment is a set of applications managed by a single tenant. They could be related logically with each other or not.
Applications within single Environment may comprise some complex configuration while applications in different Environments are always
independent from one another. Each Environment is associated with single
OpenStack project (tenant).
.. _`sessions`:
* **Session**
Since Murano environment are available for local modification for different users and from different locations, it's needed to store local modifications somewhere.
So sessions were created to provide this opportunity. After user adds application to the environment - new session is created.
After user sends environment to deploy, session with set of applications changes status to *deploying* and all other open sessions for that environment becomes invalid.
One session could be deployed only once.
* **Object Model**
Applications are defined in MuranoPL object model, which is defined as JSON object.
Murano API doesn't know anything about it.
* **Package**
A .zip archive, containing instructions for an application deployment.
* **Environment-Template**
The Environment template is the specification of a set of applications managed by a single tenant, which are
related each other. The environment template is stored in a environment template catalogue, and it can be
managed by the user (creation, deletion, updating...). Finally, it can be deployed on Openstack by translating
into an environment.

Application Management API
==========================
All applications should be created within an environment and all environment modifications are held within the session.
Local changes apply only after successful deployment of an environment session.
Get Application Details
-----------------------
Using GET requests to applications endpoint user works with list containing all
applications for specified environment. User can request whole list,
specific application, or specific attribute of specific application using tree
traversing. To request specific application, user should add to endpoint part
an application id, e.g.: */environments/<env_id>/services/<application_id>*. For
selection of specific attribute on application, simply appending part with
attribute name will work. For example to request application name, user
should use next endpoint: */environments/<env_id>/services/<application_id>/name*
