Can you be more specific? What precisely is missing from the samples  
provided at http://xmlgraphics.apache.org/fop/0.95/output.html#afp-extensions 
  ?

Yes, it was already supported in 0.95.

Andreas,

I am able to write the page segment and Overlay e.t.c in the AFP output file. But what i am looking is how to write it in the resource group. Say for example if we write a external image and give the below in config

<resource-group-file>resources.afp</resource-group-file>
<default-resource-levels goca="print-file" bitmap="print-file"/>

the image will be written in the resource group. In the same manner when i write a overlay i was not able to see it in the resource group.

Sorry, if i have to be still be more specific.

Thanks,
Bharat

Not necessary. I think I get the picture now. Thanks for the extra info.
As far as I can tell, currently, there is no support yet for similar  
functionality for the page-segment and overlay extensions (i.e. they  
will always be inlined in the AFP output file). I could be mistaken,  
though... Perhaps someone with more experience with AFP-output can  
confirm this (?)

Andreas

Hi Bharat,

Sorry for the delay in getting back to you but I'm a little swamped with
work at the moment.

As you have probably already discovered objects are placed in resource
groups using the afp:resource-level foreign attribute (see
http://xmlgraphics.apache.org/fop/trunk/output.html#afp-foreign-attributes-resource).  
Unfortunately only images and svg objects are currently supported using
<fo:external-graphic/> and <instream-foreign-object/>.  There is however
underlying support for creating overlays within resource groups in
org.apache.fop.afp.AFPDataObjectFactory.createResource (see line 226).  
So in order to achieve this feature you would need to implement a FOP
AFP extension for overlays in org.apache.fop.render.afp.extensions (see
other extension implementations in this package) and have it make use of
the afp:resource-level foreign attribute.  Then you would need to handle
this new extension in
org.apache.fop.render.afp.AFPDocumentHandler.handleExtensionObject() and
maybe also in
org.apache.fop.render.afp.AFPRenderer.renderPageObjectExtensions() for
backwards compatibility.  You would also need to make some additional
changes to resourceManager.createObject() and make a call to it, passing
it a DataObjectInfo implementation which contains details of the
overlay.  The AFPResourceManager then in turn deligates the creation of
resources to the AFPDataObjectFactory by making a call to
dataObjectFactory.createResource().

Unfortunately I do not have any time to help implement this, I only have
minimal time to spend on FOP due to other work commitments, but I would
be happy to help you further and will try to support you with the
implementation either on or off list.

Adrian.
