We are building a compressing XML database for
mobile devices (Pocket PC, Palm OS, and RIM).
The database provides local, client-side access
to XML data on mobile devices.
If you're using (or will be using) XML in a mobile
development project, we'd like to hear your
experiences and opinions -- the more opinionated, the
better. You can help us build a system that meets
your needs.
Any comments, feedback or flames can be directed
to [EMAIL PROTECTED]
Issues of particular interest to us:
+ Does your application require access to
local data on a mobile device? If so,
how much data needs to be stored locally?
Would data access mostly involve reading,
writing, or both reading and writing in
equal portions?
+ Are your mobile data storage needs best
met by a mobile XML database or the
alternatives (flat XML text files,
relational databases, application-specific
databases, etc.)?
+ Do you need to synchronize changes to XML
data between mobile devices and central
data stores? In which direction?
+ What types of application programming
interfaces (APIs) to XML data would you
find most useful on the mobile device?
DOM and XPath? From which languages?
JavaScript? VisualBasic? Java? C/C++?
C#? COM?
+ How important is data compression to
your application? Would you find a
mobile XML database capable of representing
a 3MB XML file in 900K of memory, fully
parsed and available through DOM and
XPath APIs, helpful to your off-line
applications?
+ What mobile devices are you using?
Pocket PC? Palm OS? RIM? Cell phones?
+ Do you have any experiences or war
stories that you'd like to relate regarding
XML on mobile devices? Anything that you
found particularly hard or problematic?
If you're not familiar with XML databases, one good
introduction is Ronald Bourret's summary located at:

Or an article by David McGoveran:

I have also written a white paper entitled
"XML and Handhelds: Building Mobile Applications"
located at:

Thank you in advance for your time.
