http://localhost:8890/conductor


#### pre-install:

These commands are suggested in the documentation

>> sudo aptitude install dpkg-dev build-essential autoconf automake libtool flex bison gperf gawk m4 make odbcinst libxml2-dev libssl-dev libreadline-dev

>> sudo aptitude install dpkg-dev build-essential

>> sudo aptitude install git

#### getting latest sources [ VOS 7]

create a directory for sources and move into it
>> mkdir -p ~/VOS7_sources/
>> cd ~/VOS7_sources/

get sources:
>> sudo git clone git://github.com/openlink/virtuoso-opensource.git

checkout latest stable branch:
>> cd virtuoso-opensource
>> sudo git checkout stable/7

#### installation

prepare installation
>> sudo ./autogen.sh

configure the installation to the path /usr/local/virtuoso, rename the tool isql in isql-v to avoid conflicts with the unix odbc existing one.
>> sudo ./configure --prefix=/usr/local/virtuoso/  --with-readline --program-transform-name="s/isql/isql-v/"
>> sudo nice make

run installation
>> sudo make install

#### configure

edit configuration file
>> sudo nano /usr/local/virtuoso/var/lib/virtuoso/db/virtuoso.ini

#### RUN!
run with a specific configuration file, not as a daemon (useful when developing/debugging)

>> cd /usr/local/virtuoso/bin
>> sudo ./virtuoso-t -df +configfile /usr/local/virtuoso/var/lib/virtuoso/db/virtuoso.ini


#### how-to enable federated queries
isql> grant select on "DB.DBA.SPARQL_SINV_2" to “SPARQL”;
isql> grant execute on "DB.DBA.SPARQL_SINV_IMP" to "SPARQL";

#### how-to clear a graph

* free disk after cleaning triples
no supporto: dump, delete the file on disk, and reload the data
