The DCCI work preceded the work on the UWA Ontology but it is certainly the intention that DCCI will access data that is defined with reference to the common ontology, as is the case for the DDR and most likely the OMA DPE. DCCI, however, represents data via DOM technologies, so a certain amount of datatype mapping may be required, and this may be implementation dependent. For example, DCCI uses DOMString while the ontology uses xsd:string.
DCCI provides a common way to access local device information from a Web application perspective, but it does not prescribe how this access is mapped to underlying mechanisms. It is certainly possible that the queries would map to Java APIs, but obviously this would not be the case for non-Java platforms.
Members of the UWA have already engaged in their own implementations of the DCCI and can probably share via this list their thoughts on how DCCI maps to underlying platforms.
A general set of guidelines on the use of the UWA Ontology in conjunction with DCCI has not been produced, but will be considered if the demand arises.
Hope this helps.
Note: Rhys has moved on from his previous company and is no longer participating in W3C, however I hope he is still watching the lists and will be quick to point out any errors I've made.

I have a question regarding the DCCI architecture and sent already a
message to Rhys Lewis. I have just found the public mailing list and
am forwarding my question.
Thanks to everyone in advance.

Best regards,

To: rhys@volantis.com


my name is Pantelis Katsukis and I am currently working on a diploma
thesis about dynamic device descriptions at the Ludwig Maximilians
Univerisity in Munich (LMU).
I have read about the new standards DDR API, OMA DPE (or DCAP) and DCCI.
I have got one question regarding the architecture of DCCI and I hope
you can help me.

The architectures of the DDR API and the OMA DPE are publicly available.
I cannot find any document regarding the architecture of DCCI.
DCCI is accessing device information via Javascript, but how is the
information delivered from the device? Does the device provide an XML
file with the descriptions? Are specific JSRs nedded to access the
And furthermore: Are the descriptions defined in the same ontology as
the OMA DPE ontology?

I really appreciate your help.

Thank you very much and best regards,
Pantelis Katsukis
