WHIP documentation is organized into three sections.

The metadata, namely the ‘data about data’, contains a description of all archives and variables which compose WHIP. The description includes the official name and label assigned to the variables; when the data are not self-explanatory or exhaustive, a more thorough description is also included, as well as the codes used. Moreover, there is a brief indication of the quality of the data, and when there are missing values or corrections there is a table to quantify the missing values and/or the corrections required.

A reports section, where technical reports concerning WHIP will be gathered, is forthcoming. It is an open section, which will accept contributions from users who have results related to data issues, or comparisons between WHIP and other databases.

Information concerning WHIP and its use, which cannot be filed in the meta data or technical reports, will be collected in a section of Frequently Asked Questions.
