Back from OASIS WS-DD meetings and CeBIT

March 13th, 2009

We are back  from the OASIS WS-DD interop / face-to-face meeting and the CeBIT IT exhibition in Hannover.

During the WS-DD meetings (23.-26.2. hosted by Canon at their Santa Ana, CA campus) we tested the security part of DPWS with our ws4d-gsoap toolkit. The changes will be part of a new release described later. During the face-to-face we continued the standardization work to accomplish the version 1.1 of DPWS, WS-Discovery and SOAP-over-UDP specifications until June. As you can see on the issue list, most issues are solved. So the deadline at June looks good.

During the CeBIT exhibition in Hannover we introduced our new and easy to use composition tool to create new applications in device scenarios. This time our main focus was the health care scenario. Our compositione tool called pipes attracted a lot of attention. We plan to release this tool as open source soon, so you can connect your DPWS capable devices with each other, with regular web services, web 2.0 services or even other devices that don’t support DPWS!

Apart from that we look for new application domains of DPWS. One such new application domain is distributed OSGi. So we are developing an integration of our java multi edition stack (JMEDS) into OSGi. It can be used to distribute the services of an OSGi plattform, use OSGi services with DPWS clients and integrate DPWS devices into OSGi. We are planning to release this extension soon.

To sum up our plans for the near future:

  • Release version 0.8 and 0.7.1 of ws4d-gsoap. Version 0.8 supports the latest version of the WS-DD specifications and has new features like DPWS security support, scope matching support, lwIP support, fixed interoperability issues with vista and windows 7 and maybe RTnet support. Version 0.7 simply fixes basic bugs related to the build system.
  • Release ws4d-pipes
  • Release OSGi integration for JMEDS

Public Review of WS-DD Specifications

February 5th, 2009

The OASIS Web Services Discovery and Web Services Devices Profile (WS-DD) TC has recently approved the following three (3) specifications as Committee Drafts and approved the package for public review:

  • Web Services Dynamic Discovery (WS-Discovery) Version 1.1
  • Devices Profile for Web Services Version 1.1
  • SOAP-over-UDP Version 1.1

The public review started on 2 February 2009, and ends 3 April 2009. More Informationon on the WS-DD public page.

Back from OASIS WS-DD interop and face-to-face meeting

January 6th, 2009

After joining the WS-DD Technical Comitee at OASIS Ingo Lück (University of Dortmund) and Elmar Zeeb (University of Rostock) attended the WS-DD interop and face-to-face meeting that was hosted by Software AG in San Jose, CA from 8th to 11th of December.

We were able to test our WS4D-JavaMe and WS4D-gSOAP toolkits for interoperability with several implementations from Microsoft and printer vendors that are part of the WS-DD TC. More detailed Information from the WS-DD TC about the interoperability tests will be available soon.

Furthermore we were able to participate in the standardization process and contribute our knowledge and proposals for the devices profile for web services (DPWS) to the WS-DD TC.

The TC has established a firm timeline for the production of WS-DD v1.1 specifications that will be an official OASIS Standard as of June 1, 2009. The WS-DD TC is going to standardize the SOAP-over-UDP, WS-Discovery and DPWS specification. See the WS-DD TC site for more information.

DPWS, OASIS and WS-DD

November 4th, 2008

The Devices Profile for Web Services (DPWS) – forming the basis of the WS4D tools – was submitted to the Organization for the Advancement of Structured Information Standards (OASIS). The Web Services Discovery and Web Services Devices Profile (WS-DD) Technical Committee will govern future developments and initiatives related to DPWS. The WS4D initiative is in close contact with WS-DD and will follow further progress of OASIS WS-DD in order to assure interoperability.
