CHANGELOG 
=========

DAX 1.2 -> 1.3
--------------

o There may have been some earlier adjustments from last month that
  I didn't track. I believe those were mostly bug fixes.

  - the adag@name attribute is mandatory. It will be used by the
    concrete planner as a hint to the basename of the produced cDAG
    files.

o Added missing attributes @namespace and @version to adag/job. Only the
  complete triple constitutes the primary key into the transformation
  table. The new attributes are made optional for now, because their
  counterparts in VDLx are also optional. FIXME: we may need to make
  these two attributes mandatory in all cases. 

o Removed adag/job@pfnUniverse. The universe should be specified as
  adag/job/profile with namespace of "condor", key "universe" and the
  universe as text.

  Instead of saying

	<job ... pfnUniverse="vanilla" ...>

  now use

	<job ...>
	  <profile namespace="condor" key="universe">vanilla</profile>

o Removed the "UniverseType" as consequence of the previous step.

o Removed adag/job@pfnHint. The pfnHint should be specified as
  adag/job/profile with namespace of "hints", key "application" and the
  physical filename as text.

  Instead of saying

	<job ... pfnHint="/some/path/app.exe" ...>

  now use

	<job ...>
	  <profile namespace="hints" key="application">/some/path/app.exe</profile>


o Added the "hints" profile namespace constant as consequence of
  the previous step.

o Instead of having a global element "filename" which is referenced
  by leaf elements in the adag tree, there is now a global complex
  type "FilenameType". The filename elements from previous version
  will *not* require any change. 

o The global "FilenameType" can be restricted in the special case of
  adag/job/stdio to use filename based description instead of just a
  plain name. I believe we forgot about this when we extended the
  original global filename element with the transient file handling.
  As a result, the stdio@name attribute changed to @file.

  - changed adag/job/stdin to inherit type "FilenameType" with a
    restriction on the linkage to fixed "input".
  - changed adag/job/stdout to inherit type "FilenameType" with a
    restriction on the linkage to fixed "output".
  - changed adag/job/stderr to inherit type "FilenameType" with a
    restriction on the linkage to fixed "output".

  Instead of saying

	<stdin name="lfn1"/>

  now use

	<stdin file="lfn1" link="input"/>
