HI Jamey,
The "vad_sticker.dtd" file in the Virtuoso source code (and the
documentation at http://docs.openlinksw.com/virtuoso/VAD.html)
appears to indicate that file resource elements in vad stickers will
accept a "source_uri" attribute.
When this attribute is populated, I would expect the VAD_PACK
procedure to use it to determine where to obtain the actual file
contents. But it does not appear to do so. From my reading of the
code, VAD_PACK defers to VAD_TEST_CREATE, which does not have any
logic to use the "source_uri" attribute (and instead always derives
the source path from the target path). Is that a bug? Or am I
misunderstanding the DTD and documentation?
I'm attaching a modified version of the VAD_TEST_CREATE procedure to
illustrate my question. It likely isn't entirely correct (since
this is my first time attempting to modify Virtuoso procedures), but
it does handle a simple case where the "source_uri" attribute is set
for a file resource. (The modified portions involve the "s5"
variable.)
We will be looking into this issue shortly.
Patrick
