Dimming Light. Kate Hartshorn has taken an indefinite leave of absence from contributing her insights and thoughts here. Her time and efforts have been redirected towards a difficult, but surmountable, challenge. Until her return this weblog and its Postcards from the Revolution sister will be bereft of rare points of view and a touch of humor and class that is missing from most technical resources. When she does return it will be on a permanent basis.

Shedding Light. What are web services, and why is there so much debate about a definition? I subscribe to a large number of news services and this question arises, debate ensues, issues become murky and the process repeats itself. I go with the definition that is set forth in the W3C Web Services Architecture Requirements that states:

A Web service is a software application identified by a URI, whose interfaces and binding are capable of being defined, described and discovered by XML artifacts and supports direct interactions with other software applications using XML based messages via internet-based protocols.
That wasn't too difficult. We have a definition that is sanctioned by an internationally respected body, and until a better definition comes along why not go with it? It certainly cuts through the hype spewing forth from Microsoft, Sun and the industry experts.

If you're interested in web services architecture the following resources are essential reading:

I've by no means exhausted my thoughts on this topic, and you can be sure that it will resurface again in the near future.

Bright Light. When Kate does return I promise that I'll make sure she stays around, and her place will never be filled until that time.
