1. CONNECT. TRANSFORM. AUTOMATE.
Creating Web Services with
FME Server

2. Web services

3. Create REST Web Services with FME Server

4. Web Services
 HTTP/HTTPS
 JSON or XML
 URL
 HTTP Parameters

5. Web Service Standards
 Specific URL patterns
 Specific HTTP parameters
 Specific XML and JSON payloads

6. The FME Bits
 Data Streaming service
 Workspace
 FME_SERVER_REQUEST_URI parameter
 FME_SERVER_REQUEST_HEADERS parameter
 JSON/XML Transformers

7. The Workspace
 The workspace implements the service standards
 All of the transformation abilities of FME
 FME Workbench’s ease of use

8. Three Examples
 OGC WXS
 Junaio Augmented Reality
 Subscription Management

9. FME WxS

10. Augmented Reality

11. Augmented Reality
Define a channel by providing a service URL

12. Augmented Reality
FME Server Data Streaming service URL:
 http://fmeserver.com/fmedatastreaming/junaio/sur
rey_businesses.fmw

13. Augmented Reality
Specific URL patterns defining the type of request:
 http://<host>/<service>/pois/search
 http://<host>/<service>/pois/event
 http://<host>/<service>/pois/visualsearch
 http://<host>/<service>/tools/modelencrypt
 http://<host>/<service>/tools/trackingxml

14. Augmented Reality
Specific HTTP parameters for filtering the response:
 http://<host>/<service>/pois/search?l=
(location)
 http://<host>/<service>/pois/search?p=
(search perimeter)
 http://<host>/<service>/pois/search?m=
(max features)

15. Augmented Reality
Request from Junaio Augmented Reality Browser:
 http://fmeserver.com/fmedatastreaming/junaio/sur
rey_businesses.fmw/pois/search?l=54.40,-
120.01,200&p=3000&m=40

16. Augmented Reality

17. Augmented Reality
Published Parameters Request URL

18. Augmented Reality
Specific response data format:
 AREL XML

19. Augmented Reality

20. Subscription Management
Example of Implementing a REST API

21. Let’s manage subscriptions to FME Server topics using a
web service
Subscription Management
Example of Implementing a REST API

22. Entities: devices, email addresses, WebSocket streams
Topics: places to send messages to and read messages
from
Subscriptions: agreement for an entity to receive
messages from a topic
Subscription Management
Example of Implementing a REST API

23. Let’s make it RESTful by using the URL pattern to specify
the resource to act on

24. The Subscription Manager REST API:
subscription_manager.fmw/entity/<id>/add?type=<email|apns|gcm|websockets>
subscription_manager.fmw/subscription/<topic_name>/<id>/add
subscription_manager.fmw/subscription/<topic_name>/<id>/add?confirm_token=****
subscription_manager.fmw/subscription/<topic_name>/<id>/delete
subscription_manager.fmw/subscription/<topic_name>/<id>/delete?confirm_token=**
