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

Mark,

There are a few options:

1.  As Steve suggested, use Berkeley DB for the binary content.
You can even create another DB database in the same file as
the container, and they will not interfere with one another.
This answers the question you pose, below.
You'd have to deal with backup/restore, but that's manageable.

2.  Use base64 inside XML documents.

3.  Use BDB XML metadata.  It is possible to create binary
metadata, and also create metadata-only documents.

Regards,

George
