To reinforce this community, these projects often rely on happenings centred around data creation and curation activities. We suggest an integrated framework to directly assess online community member performance in a quantitative manner and applied it to the case study of OpenStreetMap. A set of mappers who participated in both field and remote mapping-related happenings was identified. To measure the effects of happenings, we computed attributes characterising the mappers\u2019 contribution behaviour before and after the happenings and tested for significant impacts in relation to a control group. Results showed that newcomers to OpenStreetMap adopted a contribution behaviour similar to the contribution behaviour typical for the respective happening they attended: When contributing after the happening, newcomers who attended a remote mapping event tended to concentrate on creating new data with lower quality but high quantity in places foreign to their home region; newcomers who attended a field mapping event updated and enhanced existing local data with high accuracy. The behaviour of advanced mappers stayed largely unaffected by happenings. Unfortunately, our results did not reveal a positive effect on the community integration of newcomers through happenings.<\/jats:p>","DOI":"10.3390\/ijgi10030164","type":"journal-article","created":{"date-parts":[[2021,3,14]],"date-time":"2021-03-14T22:13:10Z","timestamp":1615759990000},"page":"164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["The Impact of Community Happenings in OpenStreetMap\u2014Establishing a Framework for Online Community Member Activity Analyses"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3018-2565","authenticated-orcid":false,"given":"Moritz","family":"Schott","sequence":"first","affiliation":[{"name":"Institute of Geography, GIScience, Heidelberg University, 69120 Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7393-9903","authenticated-orcid":false,"given":"Asher Yair","family":"Grinberger","sequence":"additional","affiliation":[{"name":"The Department of Geography, The Hebrew University of Jerusalem, 91905 Jerusalem, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1825-9996","authenticated-orcid":false,"given":"Sven","family":"Lautenbach","sequence":"additional","affiliation":[{"name":"HeiGIT at Heidelberg University, 69120 Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4916-9838","authenticated-orcid":false,"given":"Alexander","family":"Zipf","sequence":"additional","affiliation":[{"name":"Institute of Geography, GIScience, Heidelberg University, 69120 Heidelberg, Germany"},{"name":"HeiGIT at Heidelberg University, 69120 Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,14]]},"reference":[{"key":"ref_1","unstructured":"Ghosh, R.A., Aigrain, P., Andradas, R., Badin, R., Bernard, R., D\u00edaz, L.C., David, P., Due\u00f1a, S., Dunnewijk, T., and Glott, R.
