A short description on persistent identifiers and data citation from Research Data Netherlands.
Data citation is the practice of providing a reference to data, in the same way researchers routinely provide a bibliographic reference to outputs such as journal articles, reports and conference papers. Citing data is increasingly being recognised as one of the key practices leading to recognition of data as a primary research output. This is important because:
when datasets are routinely cited they will achieve greater validity and significance within the scholarly communications cycle
citation of data enables recognition of scholarly effort with the potential for reward based on data outputs
the use of data should be appropriately attributed in scholarly outputs as with other types of publication.

Citation of data brings numerous benefits for researchers and institutions. For example:
Evidence suggests that including citable data in related publications increases the citation rate of those publications
Routine citation of data will assist in gaining acknowledgement of data as a first class research output
Citations for published data can be included in CVs along with journal articles, reports and conference papers
Only citated data can be counted and tracked (in a similar manner to journal articles) to measure impact

Data citation standards are evolving and may vary across disciplines and publishers. However, ANDS has undertaken some work in this area and recommends using one of the following formats:
