2. Open Data Definitions
 Open Licensing
 Machine Readable
 Open Format
 Bulk Access
 Discoverable
 (http://okfn.org/opendata/)
 (http://opendefinition.org/od/)

3. Open Formats
 Shapefile
 CSV
 GeoJSON
 TopoJSON?
(Yes, there are other options)

4. Bulk Access
 Self-Host
 Socrata
 CKAN/DKAN
 GitHub? Yes, GitHub

5. File Geodatabase to Socrata
 Writing to
https://communities.socrata.com/catalog/rhok-st-louis
 Just a reader and a writer
 Edit writer feature types
 Pay attention to your geometry column

6. We get a little bit crazy
 Three different datasets
 Vague attribute names
 Some records are in the wrong projection!

7. This is Not Alternative Universe
St Louis County

8. File Geodatabase to GeoJSON
Live Demo!
Live Demo!
Live Demo!

9. ArcSDE to GeoJSON
We get more than a little bit crazy
 One Writer to rule them all
 Remove all sorts of attributes
 Use fme_feature_type to fanout
(Not crazy enough to do this live)

10. But we can do this live!
 Modify ToSocrata workbench to write GeoJSON
1. Copy transformers and dynamic GeoJSON writer
from last workbench
2. Remove the SubstringExtractor
3. Edit writer Advanced Properties
 Destination
 Fanout Attribute
4. Run?

11. So you have an error…
 Remember to set your Dynamic Properties too!
 This error fixed by adding Schema Sources

12. Bringing into GitHub (simple)
 Go to GitHub repository online
 Create a new file
 It’s text! Copy-paste!
 Save with .json extension
 Go to your file and see the pretty!

13. Bringing into GitHub (less simple)
 Use a client
https://windows.github.com/
https://mac.github.com/
 Or use git
 Zip big files! (or post-process with TopoJSON)
https://github.com/mbostock/topojson

14. Wishlist
 Publish to GitHub
 API
 Git?
 README.md writer
 Write a text file in markdown
 TopoJSON writer
 Publish Metadata to Socrata
 Might be a bit more complicated

15. Thank You!
