PEP allows for the storage and retrieval of tabular data. Conceptually, it provides a single table consisting of rows and columns.

The intersection of a row and column is called a cell. Cells do not have an identifier of their own. Instead, when storing or retrieving data, users can identify cells by specifying the associated column name and row identifier.

Access cannot be managed at the cell level: rows and columns are the smallest units for which access can be granted or revoked. Data Administrator should take this into account in their column management. If (at some point) data are to be disseminated separately, they must be stored in separate cells. Consequently, separate columns must be made available. |

# Retention

After data has been stored into a PEP cell, downloaders can retrieve that data from there. When new data are stored into the same cell, new downloads will receive the updated version instead. But the old data are never discarded: PEP retains a complete record of all data that has ever been stored into the system. This allows PEP to reconstruct its data set as it was at any time in the past. Such "snapshots" are intended to be made accessible to users for download (although the functionality has not yet been created). This allows the exact same data to be retrieved multiple times, which is usable e.g. for scientific replication studies. |
