Device Information Database [message #8908]

Hi

First of all, sorry for the crosspost. But i have a question in which
project device information access should be managed.

My first idea was the dsdp-tm project, but looking through the use cases
and the newsgroup of dsdp-tm astonished me a bit. Non of the
sub-projects in dsdp addresses device information that is fundamental
for multi-device development(at least at JavaME-Development).

I think about an abstraction of accessing multiple device-information
databases like (J2ME-Polish-Device-Database, WURFL, J2ME-Device-Database
, see
http://en.wikibooks.org/wiki/Programming:J2ME:MIDP_Device_Da tabases for
more.)

Possible there can be an abstraction, that all(or may be some)
mobile-phone manufactors can contribute data to.

Kind regards
Sebastian

Hello Sebastian,

could you elaborate a little bit what kind of use you'd want to make
from an integrated device information database?

My feeling is that for device platforms outside the mobile java
space, the hardware is perhaps just too different to fit into a
generic scheme for such device information, such that a tooling
could make use of it.

In case I'm right, the MTJ project might be the right place for
discussing this. Or does anybody know about a similar public available
database for hardware other than Java platforms?

Thanks,

Hello Martin

OK, The ideas comes as a think about a contribution for MTJ and how this
contribution should access the availiable device informations. And i
think it is not a good way that a part of MTJ accesses a device database
directly without any defined standard interface. But where to place the
definition of that interface? Maybe it is an Java independent topic. But
i have the same problem to see the need of an device information
database outside of MTJ. I am not yet very familiar with development of
- Windows Mobile
- PalmOS
- BREW
- native Symbian OS.
- ...

But i can imagine that developers for other devices than JavaME having
comparable needs for a device database.
Has the device a camera, and can it be accessed?
Does the device support alpha-transparancy?
Does it natively support bluethooth?

If not, than i looking forward to get more experience in programming
those devices and will continue the discussion in MTJ-Newsgroup only.

Are here some developers who have the need of a device information database?

Hope to hear that there is no need for an device information database
for mobile devicess outside JavaME.

Kind regard
Sebastian

E.g. people developing mobile web applications need such a database. The
"Mobile Web Initiative" (http://www.w3.org/Mobile) at w3c has a working
group which will develop an interface for existing device description
databases and a base vocabulary for such a database. See the "Device
Description Working Group" (http://www.w3.org/2005/MWI/DDWG) for details.

There are a lot of them. Thats why we maintain the J2ME Polish device
database :)

Ricky

Ok. Only one other interest. MWI/DDWG seems to be more for
WAP-Development and seems to be in an early state.

I think it is more an MTJ than an general DSDP Topic.
If there are any interrests in of the DSDP-Project-Team, they can look
at the MTH Maillinglists for additional discussion on that. I will try
to put a proposal of new Use Case at MTJ, if it does not fit in an
existing one.
