Jesus Rodriguez's WebLog

Thanks to all the folks who attended to my presentation Taming Web Services Interoperability at Oracle Open World. I've really enjoyed presenting for an Oracle-centric audience and we got some great reception and feedback . I will make the demos available next week as soon as I finish packaging them up.

On a side note, I would really like to thank to the Oracle folks who made possible to host one of the most diverse and impressive SOA tracks that I've seen on any conference so far. The session this year were distributed across some, if not all, of the most important SOA topics such as: Security, Federation, Governance, Interoperability, Complex Event Processing, Business Activity Monitoring and our always beloved ESB :).

I am really looking forward to presenting on next year's edition

This weekend I am heading to San Francisco to speak at Oracle Open World(OOW). The topic ( take a guess :) )Web Services interoperability between WCF and Oracle WebLogic. This time, I have the pleasure of sharing stage with Pyounguk Cho, Product Manager of the Oracle SOA Suite. We plan to show a real application that highlights some interesting WS-* WLS-WCF inteperability scenarios in terms of security, trust, reliable messaging, mtom and... JMS!!!  Also, this is not the only WCF session at OOW!!!!!, my good buddy Kent Brown (WCF Product Manager) will be  presenting a session about WS-AtomicTransaction interoperability...yeap it works ;).

After my session you should be able to find me at the SOA area so if you are attending to OOW and you want to chat about Oracle or Microsoft SOA technologies feel free to swing by or drop me an email at jesusmrv@gmail.com.

If you are a regular reader of this weblog you know I've been a big fan of the Resource Description Framework (RDF) for the last few years. One of my interests on RDF is its potential use on RESTful services. Unfortunately, from a practical standpoint, RDF hasn't caught up to alternative standards like the Atom Publishing Protocol (APP).  However the W3C folks keep doing a phenomenal job evolving RDF.

Yesterday, the W3C consortium published two new specs that truly highlight the flexibility of RDF: the HTTP vocabulary in RDF specification provides a way of representing the HTTP protocol elements using RDF. I find this really useful on scenarios like protocol analysis on which you need to query different HTTP elements such as headers or parameters. Additionally, W3C has also published the Representing Content in RDF specification which provides an RDF representation for the most common Web content type such as text or xml.

WS-Discovery is one of those few WS-* protocols that fills a very special gap in today's distributed programming scenarios. WS-Discovery proposes a lightweight, non-centralized mechanism for dynamically discovering services in a distributed environment. Its applicability is especially important on sensors and devices networks where nodes change location constantly.  Typically, WS-Discovery is used in combination with UDP in order to broadcast discovery messages to different nodes.

In recent days, OASIS formed a new committee for defining a subset of the WS-Discovery set of specifications that can be applied on control devices.  I am more and more skeptical about the work on WS Standards lately, but I think this committee can have a positive impact in the adoptions of WS-Discovery.
