The Croatian Association for Open Systems and Internet (HrOpen) was established in 1992. HrOpen is a self-financed, non-profit association modelled after many other similar European associations. From 1993 to 1998, HrOpen was a member of the European Forum for Open Systems. Since 2010, HrOpen has been a member of the OpenForum Europe, an OSS advocacy group with headquarters in Brussels, Belgium.
HrOpen is tasked with promoting FLOSS technology through workshops, seminars and conferences, and providing help by consulting through expert groups. More details about the association itself are available at: www.open.hr
