Research data management
Proper citation should be a significant feature of any publication that references anything created by someone else. It should also include references to any primary or secondary data sources used.
Making a data collection citable and encouraging users to cite it:
There aren't any strict standards for citing data so far. Some of the publishing houses have started to provide guidance on citing databases and everyone has to learn them one by one when publishing.
However, there are some mandatory fields:
Moosus, M.; Maran, U.; (2014): Moosus, M.; Maran, U. Quantitative structure-activity relationship analysis of acute toxicity of diverse chemicals to Daphnia magna with whole molecule descriptors. SAR and QSAR in Environmental Research 2011, 22, 7-8, 757–774.; QsarDB repository (http://qsardb.org/). http://dx.doi.org/10.15152/QDB.111

The registry of DataCite provides citation in two ways: The most used formats (APA, Harvard, MLA, Vancouver, Chicago, IEEE, BibTeX, RIS) are available just with the dataset or one can use Citation Formatter for more than 5000 extra formats.
