Data-centric projects, among them, often require integration of disparate data source formats and collection methods, leading to complex data management architectures and policies. This article is an extended version of an article presented at the 1st International Conference on Big Data Analytics and Applications (BDAA\u20192025). It explores design decisions, organisational principles, and technological solutions to address these challenges by focusing on data integration of data sources and the hybridisation of data services. This experience was gathered while working on DiverSea, a project dedicated to the analysis of biodiversity dynamics along European coastlines\u2014ranging from the Black Sea to the Mediterranean and the North Sea. While grounded in established technologies, the project\u2019s takeaways offer valuable insights for environmental data projects across aquatic, terrestrial, and atmospheric domains.<\/jats:p>","DOI":"10.3390\/a19020154","type":"journal-article","created":{"date-parts":[[2026,2,16]],"date-time":"2026-02-16T08:38:39Z","timestamp":1771231119000},"page":"154","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Data Management and Data Services in Large Collaborative Projects\u2014DiverSea Experience"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4361-4830","authenticated-orcid":false,"given":"Vassil","family":"Vassilev","sequence":"first","affiliation":[{"name":"GATE Institute, Sofia University, 5 James Bouchier Blvd, 1164 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0205-585X","authenticated-orcid":false,"given":"Georgi","family":"Petkov","sequence":"additional","affiliation":[{"name":"GATE Institute, Sofia University, 5 James Bouchier Blvd, 1164 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Boris","family":"Kraychev","sequence":"additional","affiliation":[{"name":"GATE Institute, Sofia University, 5 James Bouchier Blvd, 1164 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stoyan","family":"Haydushki","sequence":"additional","affiliation":[{"name":"GATE Institute, Sofia University, 5 James Bouchier Blvd, 1164 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4474-515X","authenticated-orcid":false,"given":"Stoyan","family":"Nikolov","sequence":"additional","affiliation":[{"name":"GATE Institute, Sofia University, 5 James Bouchier Blvd, 1164 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Viktor","family":"Sowinski-Mydlarz","sequence":"additional","affiliation":[{"name":"School of Computing and Digital Media, London Metropolitan University, 166-220 Holloway Road, London N7 8DB, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9700-8351","authenticated-orcid":false,"given":"Ensiye","family":"Kiyamousavi","sequence":"additional","affiliation":[{"name":"GATE Institute, Sofia University, 5 James Bouchier Blvd, 1164 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikolay","family":"Shivarov","sequence":"additional","affiliation":[{"name":"GATE Institute, Sofia University, 5 James Bouchier Blvd, 1164 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-7459-4010","authenticated-orcid":false,"given":"Denitsa","family":"Stoilova","sequence":"additional","affiliation":[{"name":"GATE Institute, Sofia University, 5 James Bouchier Blvd, 1164 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,15]]},"reference":[{"key":"ref_1","unstructured":"Vassilev, V., Petkov, G., Kraychev, B., Haydushki, S., Sowinski-Mydlarz, V., Nikolov, S., and Shivarov, N.
