RE: *URGENT* -- Call for support



Thanks Eric for sharing your views on Ozone. I am fairly new to the world of 
Java and XML and don't feel qualified to offer much guidance on the future 
path for Ozone but would like to share my thoughts.

The work that Falko and others on the Ozone team have done is very 
impressive and the core Ozone engine appears to be quite solid. Yet there 
does not seem to be a great deal of interest in Ozone and I was thinking 
about what might help broaden the appeal of Ozone.

Related to this I found your comments on JDO quite interesting. JDO 
compliance looks like a necessary capability to be a serious entry in the 
Java dbms market. (for an intro to JDO see 
http://www.javareport.com/html/from_pages/view_recent_articles_jr.cfm?ArticleID=688 
)

Falko, do you have a sense of how much work it would take to make Ozone JDO 
compliant?

It seems alignment with JDO might help broaden Ozone's appeal. For a 
prospective user having minimum dependence on a single product can be a real 
plus.

The need for a query capability comes up periodicaly on this list. Although 
it pretty sketchy at this point, the JDO spec attempts to address the query 
issue in a way that is query language neutral. I think that having even a 
minimal query capability would be a real plus for Ozone. Given clear goals, 
specifications and constraints this is an area where I could contribute.

On the surface it isn't obvious how the proposed JDO query approach would be 
useful if Ozone were being used as an XML repository. I agree with Eric's 
statement that 'xml is definitely not a storage format, it's only an 
exchange format'. To me it seems some of the issues raised here concerning 
XML and Ozone may be due to an inappropriate use of the technology.

Falko, as I mentioned at the end of last year over the next couple of weeks 
I'll be putting together a writeup of our experiences to date with Ozone. 
(They've been very positive!). Last week I gave the first demo at our core 
distributers conference of our new product which will use Ozone. A few weeks 
before the conference I was given a requirement for some major new 
capabilities that required significant structural changes to the database. 
The changes were made and worked. I wouldn't even want to try that with a 
RDBMS under the app.

cheers,

don
