This document summarizes the agenda and projects presented at the FME Hackathon 2020 focused on the theme of "Connections". Four projects were highlighted that demonstrated innovative uses of FME to create connections: 1) an augmented reality application to connect remote colleagues, 2) predictive COVID-19 modeling to aid school reopening plans, 3) an application to find connections between workspaces and transformers, and 4) an augmented reality application to virtually interact with FME founders. Participants voted for their favorite project for prizes supporting mental health charities.

3. The Theme:
“Connections”
2020’s been rough.
We’ve learned that staying connected to
those around us is more important than
ever.
In line with this, our theme for this year’s
Hackathon was “Connections”, where
we focused on celebrating users coming
together to ideate, experiment and build
solutions.

4. Watch for innovative
FME Solutions & Tips
In this webinar, we will:
● Highlight some awesome
solutions that our FME user
base came up with
● Teach you some FME tips &
tricks along the way

5. Welcome to our
User Judges!
You are an important part of
today. Here’s some criteria to
consider while judging:
● Extent to which project
creates connections
● Use of FME and range of
FME functionality

6. What’s at Stake: Prizes!
● Donation to the World Federation for Mental Health
● $500 donation to a charity of the winning teams choice
● FME Swag pack

Project 1:
Connecting with Colleagues

8. Connecting with Colleagues
Working at home can be lonely… but so can working
in an empty office!

9. ConnectingwithColleagues

10. Summary
● Simple, but effective. Usable anywhere.
● Uses latest AR technology.
● Scalable and expandable. Great potential:
○ Status balloons
○ Contact details
○ Full office directory
○ Emergency response tool
Connecting with Colleagues

11. Project 2:
Predictive Analysis of COVID-19 cases
by Regional Education Coordinators
in the City of Rio de Janeiro with FME
Debora Simas, Rodrigo Ferrão, Victor Barone
GeoInsights Rio

12. Predictive Analysis of COVID-19 in Rio de Janeiro
Problem
● Brazil has the second highest number cases of COVID-19 of any other country
● Regional Education Coordinators (RECs) are responsible for strategic planning of
schools in the municipalities
● 11 RECs are responsible for returning to classes post-pandemic
Solution
● Use FME and R to create a predictive analysis model for each educational region to
help with planning the safe return to classes

13. Predictive Analysis of COVID-19 in Rio de Janeiro
Data Preparation
● Download the COVID-19 case data
● Download Census data
● Clean Census data
● Calculate Death Rate, Fatality Rate, Incidence Rate
RCaller
● Predictive analysis done using Random Forest model

Project 3: Applications Connection Finder

17. Application Connection Finder
Requirement
● If I edit a custom transformer, to test it I need to know where that transformer is
used.
● If I edit a workspace, to test it I need to know if it is used in a sequence of
workspaces.
Connections
● Find connections between workspaces that are called from other workspaces
● Find connections between custom transformers that are called from other
workspaces

18. Application Connection Finder

19. Application Connection Finder
Step 1
● Retrieve workspaces from Server (all HTTPCallers):
○ Get Token: @Value(Server)/fmetoken/generate.json
○ Get Repositories: @Value(Server)/fmerest/v3/repositories
○ Get Workspace List: @Value(Server)/fmerest/v3/repositories/@Value(repository)/items
○ Retrieve Workspaces: @Value(Server)/fmerest/v3/repositories/@Value(repository)/items/@Value(workspace)
Step 2
● Read workspace contents:
○ FeatureReader: FMW Workspace Format

20. Application Connection Finder
Step 3
● Find workspaces with an FMEServerJobSubmitter transformer:
○ TestFilter: @Value(transformer_type) = FMEServerJobSubmitter
● Find workspaces called by an FMEServerJobSubmitter
○ TestFilter: @Value(transformer_parameter_name = WORKSPACE_NAME)
○ TestFilter: @Value(transformer_parameter_value) HAS A VALUE
● Return workspace IDs
Step 4
● Find Custom Transformers embedded inside a Workspace
○ TestFilter: @Value(transformer_type) = SubDocumentTransformer
● Match Custom Transformers inside a workspace to Custom Transformers from Server:
○ FeatureMerger: TransformerName (Workspace) = TransformerName (Custom Transformer)

21. Application Connection Finder
Summary
● Fills a gap in the range of FME functionality
● Makes excellent use of the FMW Format reader
● Could easily be adapted to produce HTML reports streamed via Server
● Has potential to add other connections later (and not limited to FME)
○ Workspaces used in Server automations
○ Workspaces called from other applications, like ArcGIS
○ Workspaces using ArcGIS services

22. Project 4:
