| Exercise 2 | Basic Workspace Creation |
| Data | Zoning Data (MapInfo TAB) |
| Overall Goal | Create a workspace to translate zoning data in MapInfo TAB format to GeoJSON (Geographic JavaScript Object Notation) |
| Demonstrates | Basic workspace creation with FME Workbench |

Congratulations! You have just landed a job as technical analyst in the GIS department of your local city. Your old schoolteacher, Miss Vector, gave you a reference, so don't let her down!
On your first day you've been asked to do a simple file format translation.
We’ve outlined all of the actions you need to take; though FME's interface is so intuitive you should be able to carry out the exercise without the need for these step-by-step instructions.
1) Start FME Workbench
If it isn't open already, start FME Workbench by selecting it from the Windows start menu. You’ll find it under Start > FME Desktop 2018.0 > FME Workbench 2018.0.
If Workbench is already open, click on the Start tab above the main canvas.
2) Select Generate Workspace
In the Create Workspace part of the Start page select the option to Generate (Workspace). Alternatively you can use the shortcut Ctrl+G.
3) Define Translation
The Generate Workspace tool opens up a dialog in which to define the translation to be carried out. Fill in the fields in this dialog as follows:
| Reader Format | MapInfo TAB (MITAB) |
| Reader Dataset | C:\FMEData2018\Data\Zoning\Zones.tab |
| Writer Format | GeoJSON (Geographic JavaScript Object Notation) |
| Writer Dataset | C:\FMEData2018\Output\Training\Zones.json |
The dialog will look like this:
Remember, you can set a format by typing its name, by selecting it from the drop- down list, or by choosing “More Formats” and selecting the format from the full table of formats. For now, ignore the Workflow Options and leave the default of 'Static Schema.'
4) Generate and Examine Workspace
Click OK to close the Generate Workspace dialog. A new workspace will be generated into the FME Workbench canvas:
The list of attributes is exposed by clicking the arrow icon on each object.
5) Run Workspace
Run the workspace by clicking the run button on the toolbar, or by using Run > Run Translation on the menubar. The workspace runs and the log file reports a successful translation:
6) Locate Output
Locate the destination data in Windows Explorer to prove that it's been written as expected (don't forget the Open Containing Folder button from Exercise 1). In the next section we’ll cover how to inspect the dataset visually to ensure that it is correct.
7) Save Workspace
Save the workspace. We'll be using it in a later exercise. Remember there is a toolbar save button and on the menu there is File > Save As.
| TIP |
| When a translation is run immediately without adjustment it's known as a "Quick Translation". Because FME is a 'semantic' translator, with an enhanced data model, the output from a quick translation is as close to the source data in structure and meaning as possible, given the capabilities of the destination format. |
