After execution of the API method population_import in Façade #2 its "populations" section shows the following triples (note that the fourth column, turning these triples into "populations" section quads, is left out for real estate reasons). Note that, for this case, we assume that already one earlier population took place. This means that you will find the traces of that in that "populations" section. Below the first table we show a second table with the contents of that "populations" section after execution of the populate API method. The blobs have been converted to quads, and these quads have been used to populate the "data" section of that façade. After successful execution of the populate method the blob is archived. All archived blobs for the populations and the handovers section of the façade together can be used to recreate the façade contents in case of a disk crash or other fatality. Take notice of the fact that this section is different from that of Façade #1. The reason for that is that there is no other way to store the transmission data for the initial loading from a user application (since that in itself is not a façade). In all other situations the transmission data of a transfer are stored in the "handovers" section of the sending façade. |
The colors mean:
| the standard heading | |
| the transmission data | |
| the payload |
Quads 7 - 10 are representing an earlier (on January 17th) population.

After successful execution of the populate API method the 'content' of the RdfXmlLiteral is archived, the 'containedIn' and 'archiveLocation' properties
stay in the "populations" section.
Through that transmittal URI the transmission data can be retrieved, and from that archive location the 'content' can be retrieved.
The "populations" section of Façade #2 then looks like this:
