org.gephi.project.api.Workspace
Workspace interface that internally stores, through its Lookup, various information and instances.
Workpace is a top concept in Gephi because all models that modules possesses are usually divided by workspace, for instance one GraphModel per workspace. Therefore this class has a Lookup mechanism to let modules store their model in the workspace's lookup and query it when needed.
To know how you can manage loading and saving data in Gephi project files, see {@link WorkspacePersistenceProvider}.
How to associate new data model to the workspace
In your new module, listen to {@link WorkspaceListener} and call add()method when initialize:
```
public void initialize(Workspace workspace) { workspace.add(new MyDataModel()) } 
```
When a workspace is selected, retrieve the workspace's data model:
```
public void select(Workspace workspace) { MyDataModel model = workspace.getLookup().lookup(MyDataModel.class); } 
```
