FME Objects Python API 5 Using FME Objects Python API to Provide Platform Independent Translations Project Overview  Geoscience Australia  plays a critical role by producing first-class geoscientific information and knowledge. This can enable the government and the community to make informed decisions about the exploration of resources, the management of the environment, the safety of critical infrastructure and the resultant wellbeing of all Australians.

FME Objects Python API 6 Using FME Objects Python API to Provide Platform Independent Translations Project Overview  Geographic Data Management Division  Solution Name - Geoflex  Project Leader - Tony Hunter  Formats Supported  ESRI Shape File (.shp,.shx,.dxf)  Personal Geodatabase  Mapinfo Native Format (.tab), Mapinfo Data Interchange Format (.mif), and  Geographic Mark-up Language (.gml)

FME Objects Python API 7 Using FME Objects Python API to Provide Platform Independent Translations Project Overview  Requirements  Be platform independent i.e. the core extraction process is able to execute on both Windows and Unix Operating Systems  Allow a User to Select the Feature Dataset to be extracted  Allow a User to Extract the datasets to on 3 scales  National  State/Province  Map Tile  Custom Symbology Developed by GA to be applied to the Output Datasets  Dynamically update the list of Feature Datasets that are available for extraction through interrogating the underlining Spatial DBMS schema

FME Objects Python API 8 Using FME Objects Python API to Provide Platform Independent Translations Platform Independent Translations with FMEObject for Python  Method  FME Workbench to Develop the Translation Process

FME Objects Python API 14 Using FME Objects Python API to Provide Platform Independent Translations  Save the pasted output as one or more.fmi files  Use the FMEFactoryPipeline.addFactoriesFrom File() method to include your translation pipeline.fmi files into your PyFMEObjects Script.

FME Objects Python API 15 Using FME Objects Python API to Provide Platform Independent Translations  WHY???  Reduce possible errors in your script  Special Characters \n – New line \r – Carriage Return \w – White Space \t – Tab !!!  Special characters MEAN something in both Python and FME Mapping Files

FME Objects Python API 16 Using FME Objects Python API to Provide Platform Independent Translations  Allows you to solve other bugs  Logical  Programmatic  Data Flow  Logical –  If…Then…Else  Do…Loop  Switch…Case

FME Objects Python API 17 Using FME Objects Python API to Provide Platform Independent Translations  Allows you to solve other bugs  Logical  Programmatic  Data Flow  Programmatic –  Incorrect Method use  String Manipulation  Reading Multiple Source Datasets

FME Objects Python API 18 Using FME Objects Python API to Provide Platform Independent Translations  Allows you to solve other bugs  Logical  Programmatic  Data Flow  Data Flow –  Combination of Logical and Programmatic Errors  Unexpected output

FME Objects Python API 19 Using FME Objects Python API to Provide Platform Independent Translations  Once you have your Python script reproducing the same output as Workbench, its time to Embed your Factories  …which is also where the fun begins!!

FME Objects Python API 20 Using FME Objects Python API to Provide Platform Independent Translations  First of all…  Use the Python Lists i.e.  stringListVariable = [‘green’, ‘eggs’, ‘and’, ‘ham’]  Cuts out the possibility of naughty special characters sneaking their way into your Factory Definition  i.e. DON’T USE THE “””green eggs and ham“”” strings – it tells Python to use the string as it is, Naughty Special Characters and all

FME Objects Python API 23 Using FME Objects Python API to Provide Platform Independent Translations  Why Use Python?  Great ‘Whipitupability’  It is an ‘interpreted’ language  Its free and powerful!!! With a great open source community  Supported by ESRI and FME  You can write your own transformers for FME
