Released 2005
Confirms current value. GraphDB began as OWLIM; a public OWLIM v2.8 announcement is dated October 2005, meaning the first release predates that and falls in 2005 or earlier — no earlier public announcement was found, so 2005 is treated as the release year rather than an exact first version.
