expand_less As corporate reporting frameworks, standards, legislation, and entity structures constantly change, what companies are disclosing and are expected to disclose, is constantly changing too. Therefore, it is virtually impossible to keep all data up to date. A metric question that had lots of data one year, might be barely disclosed in another year. 
It is also important to note that by design, Wikirate is an imperfect database in the sense of data “completeness”. The reason being that as a wiki, we allow anyone to create questions that they believe companies should have an answer to. That means the amount of answers available for that question can vary a lot.
That said, current and consistent company data is absolutely worth striving for.
All data on Wikirate is associated with a specific calendar year and includes a timestamp of when the information was last updated. While most data is published annually (following financial year cycles), some data types might be produced quarterly, or rather every couple of years, or even at irregular intervals (like violations data).
Semi and fully structured datasets, collected through automated techniques like API integrations and scraping, are updated by the Wikirate Team on a regular schedule.
The regularity of updates for data coming in through bespoke Research Projects on Wikirate is dependent on a few different factors, including the availability of funds and the fit with research and campaigning interests of the Community.
For research data that is produced off-platform and is added in bulk by project partners, the Wikirate Team reaches out to encourage updates when new data is published.
Ultimately, the best way to ensure that data associated with your organization or the topics and companies that interest you is kept current, is to create a profile on Wikirate and maintain the data yourself.
