Re: [bdbxml] I want to store binary content in my DBXML

The trick is that I'm trying to use BDBXML as my file format for my
application and I want to use the BDBXML/BDB API's to access it all. I
want to be able to transport the whole contents of my applications
"Document" as one file without any heavy duty repackaging efforts on my
part, I want to promote the BDBXML API as the API for Application
developers to use when accessing my files (instead of authoring my own API).

This is why it'd be advantageous to store them in the DB along with the
XML. From a storage standpoint, I could tolerate them being in something
like Base64 because theres lots of standard Base64 conversion libraries
to get them back out in various languages. I just think that it might be
better if I went down to the level of Berkeley DB as opposed to being
Base64 text in a BDBXML document since Base64 increases the storage
requirements by a ratio of 4:3, it'd be better to be able to store the
bytes in their native encoding (or even compressed) to save space.

This is a library application and there are allot of XML formats that
like to include the ability to hold binary Base64 encoded content as
values. But mostly they are just for transport, not storage.

Does this make any sense?

thanks for your advice,
Mark
