I am somewhat of a newbee to VOS, but not to programming and
development. I am really amazed that there is such a product and so
little buzz about it yet. Hopefully, as the Semantic Web takes off
then more people will discover this platform, as it certainly fills
the bill for so many capabilities.
My question concerns the basics of getting started in development.
So for example, I wanted to write the equivalent of a "Hello World"
for the VOS that uses the vsp language. I have successfully
installed VOS and most of ODS on Gentoo Linux with the defaults. So
the VOS files reside in /usr/local/virtuoso-opensource. Since the
home page seems to run from this directory: /usr/loca/virtuoso-
opensource/var/lib/virtuoso/vsp , I created some hello world files
in the directory. I can run straight HTML from the directory
without any problem. And in the HTML file, I can include the
index_left.vsp or my own vsp file (as an iframe) if I have the
included files in the admin sub-directory. But if I try to create
another sub-directory (e.g., admin2) and include a vsp file or if I
try to include a vsp file in the home directory (not in the admin
subdirectory), then I get an error "The requested active content
cannot be displayed due to execution restriction". Obviously this
is a permissions issue, but I could not find anything fruitful in
the documentation on ACL or anywhere else and so was wondering if
anyone could point me in the right direction on how to set up
permissions and/or how to go about creating a simple "Hello World"
program that will execute some vsp code in it.
Thanks in advance for any reply.
