 Dear José Manuel Cantera ,

The Mobile Web Initiative Device Description Working Group has reviewed
the comments you sent [1] on the Last Call Working Draft [2] of the Device
Description Repository Simple API published on 4 Apr 2008. Thank you for
having taken the time to review the document and to send us comments!

The Working Group's response to your comment is included below, and has
been implemented in the new version of the document available at:

Please review it carefully and let us know by email at
public-ddwg-comments@w3.org if you agree with it or not before 5 June
2008. In case of disagreement, you are requested to provide a specific
solution for or a path to a consensus with the Working Group. If such a
consensus cannot be achieved, you will be given the opportunity to raise a
formal objection which will then be reviewed by the Director during the
transition of this document to the next stage in the W3C Recommendation


For the Mobile Web Initiative Device Description Working Group,
Matt Womer

Your comment on Get Data Version public String getDataVersion();
> Regarding the method getDataVersion of the Service interface,
> It is said

> it does have a versioning system for data then this value must change
> between calls if the implementation can not guarantee that the data is

> Proposed Amendment:
> + Remove the getDataVersion method of the Service interface

Working Group Resolution (LC-1956):
The DDWG has resolved to simplify the getDataVersion description to say
only that when the method is invoked it will return the version of the
device description data or a particular constant value (to be defined in
the specification), which would indicate that versioning of the data is
not supported. There will be no specific mention of throwing a
SystemException since such exceptions may be thrown by any method.
