Report template for generating final configuration files from RDF data

  • The report template is interpreted by my RDF report generating software [1]

The report template consists of:

  • control logic, e.g.:

:GenHostDetails :-
  (
    [ rep:cmd rep:for   ; rep:pattern :HostPattern ;
      rep:do
        ( [ rep:cmd rep:write ; rep:chan "dhc" ; rep:data :DHCHost ]
          [ rep:cmd rep:write ; rep:chan "dns" ; rep:data :DNSHost ]
        )
    ]
  ) .

  • query patterns, e.g.:

:HostPattern :-
  ( [ rep:var "Host" ]
    [ rep:and
      ( [ rep:uri user:hostName ]       [ rep:var "HostName" ] ),
      ( [ rep:uri rdfs:label ]          [ rep:var "HostLabel" ] ),
      ( [ rep:uri dnsa:hostDomainName ] [ rep:var "HostFQDN" ] ),
      ( [ rep:uri dnsa:hostIPAddress ]  [ rep:var "HostIP" ] ),
      ( [ rep:uri dhcp:hostMACAddress ] [ rep:var "HostMAC" ] )
    ]
  ) .

  • output templates, e.g.:

:DHCHost :-
  ( "host " [rep:var "HostName"] rep:nl
    "    {" rep:nl
    "    hardware ethernet " [rep:var "HostMAC"]  " ;" rep:nl
    "    fixed-address     " [rep:var "HostFQDN"] " ;" rep:nl
    "    }" rep:nl
  ) .
