 SteveGibson: For us, we use a lot of XML already, so being able to keep XML for me is very
important. A lot of people are saying they don't want to invent a new language - SDL. Well,
to me, this looks a lot like IBMs Stanza format, used in AIX forever, and also the configuration
format a company I used to work for came up with - purely because you specify the object you
want to create and assign the properties. I think the SDL is very readable, and would probably
use it if we didn't already use lots of XML files and *gasp* properties files.
 NareshSikha: I hope that the bulk of Hivemind Services and Configurations are written by
junior developers who are more concerned about their resume than the strength of the architecture
they are fulfilling. This will afford more time for architects and leads to solve the interesting
problems. Therefore I think '''tools''' should be delivered to help developers author valid
module definitions (Eclipse plugins are a good starting point). Then the details of the definition
are more or less irrelevant. Barring that, please, please, give junior developers a chance
to strengthen their resume by allowing for industry standard means for communicating metadata
+AchimHuegen: Now that I worked with SDL I would like to share my opinion: I don't think the
benefit of SDL is big enough to counter-balance the disadvantages. 
+The main differences to XML are the use of curly braces instead of start and end tags and
the way of quoting. The use of braces enhances readability on the one hand but reduces it
on the other hand for larger files. Apparently the verbose xml format is sometimes even helpful.
I couldn't resist to quote the main hivemodule.sdl, sorry howard ;-) :
+{{{    }  // element construct
+  } // parameters-schema
+Use of quotation marks is simply inverted, which could be a bit confusing:
+<bean name="bean2">
+  <string>testValue2</string>
+bean (name=bean2)
+  string { "testValue2" }
+The differences are subtle but must be learned by developers. Furthermore, there are still
some open questions like encoding (character sets). 
+I think, the main problem behind "too much xml" is not the xml format itself, but the definition
of verbose schemes and the shifting of programming logic to xml files. The definition of proprietary
formats by each library is no solution for these problems.
