The "Outputs of the NISO Alternative Assessment Project," published in 2016, presented an Altmetrics Data Code of Conduct “aiming to improve the quality of altmetric data by increasing the transparency of data provision and aggregation as well as ensuring replicability and accuracy of online events used to generate altmetrics” (section 5).
Key recommendations of this code of conduct include:
This code of conduct encourages altmetric data providers and altmetric data aggregators to share an annual public report on how they have met the above recommendations.
Altmetric providers are encouraged to provide clear and well-documented verification of:
How the data is generated, collected, and curated
How the data is aggregated
When and how often the data is updated
How the data can be accessed
How data quality is monitored
Altmetric data providers are encouraged to deliver a set of data that will be consistent over time.
To do so, they should ensure that:
The data is generated using the same methods over time
Methodology changes and their effects are documented and thoroughly explained
Data errors are well documented
Data provided to different user groups is the same
Information is provided on how the data can be independently verified
Altmetric data providers are encouraged to provide accurate data were:
Known errors are identified and corrected
Limitations of the data are communicated
The data represents what it implies to reflect
