Glossary
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).
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.

Multiple sessions could be opened for one environment simultaneously, but only one session going to be deployed.

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
