Re: [xml-dev] Long overdue update to the UBL to UN Layout Key free rendering environment

Not that I know of.

But ... this approach isn't standardized anywhere.  I'm using my own 
Crane namespace for the XMP metadata RDF section that contains the 
XML in clear text.

Since XMP content cannot contain structured XML, only fielded XML, 
the XML instance is reconstituted from the XDM in a single XMP field 
as clear text and not as markup, thus requiring the second step of 
serializing the clear text as markup.  Thankfully this is easy in 
XSLT.  So I use Python to extract the XMP (if I'm not using Acrobat) 
and XSLT to create the parsed content.

And I make these tools freely available so that the process is auditable.

I hope to publish a revision today that more accurately reflects the 
actual input document syntax rather than the reconstituted input 
document syntax in the XMP clear text.

I won't announce the revision here, but I have an RSS feed of 
releases of all of our free developer resources and so revisions can 
be found using this:


Do you have ideas, Stephen, for anything catchy to call this?

I'm hoping this will be of interest to others, but I haven't had any 
feedback to know if the efforts were worthwhile.

If anyone working on standardizing PDF is interested in standardizing 
a scheme for embedding XML in a PDF file, I'll gladly change what I'm doing.

Thanks, Stephen.
