In the directory for each database are three files findex.db, rindex.db and arcindex.db.
You can run rdfDB from the command line like this :
shell>nohup ./rdfdb &It will print out the version number.
There is a perl library to issue queries and get answers which can be downloaded from here. The perl library needs to be made into a DBI driver. I am also planning on providing a C client library.
rdfDB connections are very lightweight and can easily be created and terminated. rdfDB is multi-threaded and each connection gets its own thread. Right now, a new thread is created for each connection, but I plan to switch to a connection pool soon.
Queries are terminated with the string "</>". The response is zero or more lines, followed by the line
<result-code> </>The result codes are described here. The result code 0 represents successful completion of the request. The last line is the only one which may contain </>.
