Specimen/collection citation should have similar currency to publications.
We need best practices that can engage all the actors and entities involved in the lifecycle of the data (for example from data collection during expeditions to different levels of data aggregation). These engagements and best practices, along with a s sustainable technical infrastructure and standards, should entail clear and consistent guidance. However in order to sustain these best practices we need tracking and reporting mechanism as it provides incentive for the citation.
Incentive can also be provided by the funding agencies. Several funding agencies already require that data need to be open and FAIR but the requirements are less specific in terms of citations and identifiers.
