The Milestone MS283 summarises the results of the Third EU BON Training Event and its evaluation based on the participants feedback. This training was in fact part of the training for Global Biodiversity Information Facility (GBIF) Node Manager organized by the GBIF and held in Madagascar, Antananarivo on 4-5 of October 2015. The EU BON representative (Larissa Smirnova, MRAC) was invited to facilitate the sample data publishing session and MRAC has been also entrusted to write a manual summarizing the best practice for publishing sample data (lead by Patricia Mergen). The training event addressed a core topic for GBIF: the publishing of biodiversity data online. Diverse data types were covered and sample-based data were introduced. The accent was made on the hands-on sessions using the new version of the GBIF Integrated Publishing Toolkit (IPT v.2.3) which was adapted in collaboration with EU BON to enable the flow of sample-based data in support of Essential Biodiversity Variables (EBVs.
