5. Alternative Flavors: REST vs. SOAP
 HTTP by itself: GET,
POST, PUT, DELETE
 REST design pattern
 Good for browser-
based apps (e.g.
JavaScript)

6. Alternative Flavors: REST vs. SOAP
 SOAP over HTTP
 Leverage WS-*
standards
 Web protocols
incidental to design
of apps

7. Benefits
 Everyone speaks web: get data with platforms,
languages where DDS port is impractical
– Novel embedded platforms, e.g. Android
– Scripting languages, e.g. JavaScript, Python, Perl
 No software to deploy: “application” is just a web site
 No waiting for discovery: pub and sub from ephemeral
clients
– e.g. simple command-line tools
 Easily build web service mash-ups
– Combine data from DDS, other web services into single view
– e.g. Google Maps example

8. State of the Union
 Early-Access Release available on portal
– Windows and Linux, 32-bit
– SOAP and REST support
– Proof-of-concept access control
– Deploy with built-in web server or in Java EE container
– Code examples
– Standard doc set: Getting Started, Manual, Release Notes
– Video of Google Maps demo on the web (thanks, Rajive)
 “Web-Enabled DDS” in-process at OMG
– RTI, PrismTech, Thales working together
– Next proposal revision due end of this year
