Subject Re: [PROPOSAL] Combine ODFDOM and Simple API
Date Thu, 23 Feb 2012 10:02:19 GMT
Hi Devin,

just my 0.05CHF:

IMO, separating logically different modules promotes cleaner and clearer
dependencies. No accidental reference from ODFDOM into Simple API. Both
APIs have a different sort of client. Some may not even need Simple at
all. Lately doing a lot of OSGi I like smaller OSGi bundles (a bundle is
basically a normal JAR with additional metadata).

In the end, I think it's only a question of packaging. You could always
create a combined JAR that contains both ODFDOM and Simple. Apache Batik,
for example, provides both: multiple JARs for each module and a single
"All-JAR". However, Batik has only a single, large source tree. That
makes keeping dependencies clean a challenge. Apache FOP has a single
source tree, too, but contains multiple modules that could easily be
used outside the context of XSL-FO. Or an output format called AFP is
used only by a minority of all FOP users but it takes up a large
portion for fop.jar. Both project would profit from splitting up into
modules. It also makes the source code less threatening to newbies, I

I believe it should also be possible to create a single Javadoc run for
all subprojects. At least other projects I've seen seem to do that.

As for naming (your question (1)): you could still have odfdom.jar,
simple.jar and add odf-toolkit.jar containing everything.

BTW, the ODF Toolkit website needs an overhaul to use the new Simple API.
Even the first example on the front page uses deprecated API. BTW, since
Simple API is a new API I'm kind of surprised that it doesn't use
org.apache.odftoolkit.simple as package name. Since ODF Toolkit has a
<1.0 version number, I'd be relatively quick to remove deprecated API.
It makes finding your way around a little difficult as a newbie. Or
maybe it is possible to move the old simple API to a separate legacy
package to clean up ODFOM.
