Below is a Transfer File sent from Facade #1 to Facade #2, with explanations at the righthand side.
It results from execution of the handover_export API method of Façade #1.
The colors mean:
| the standard heading | |
| the transmission data | |
| the payload |

This is a special construct that is called rdf:XMLLiteral. In the Reference Data Library it has been defined as RdfXmlLiteral, a subclassOf &part2:ClassOfInformationRepresentation. In the 'containedIn' property reference is made to the transmittal that is stored in the sending façade. In the 'archiveLocation' a URL is given in which the "payload" is archived after successful transfer. In the 'content' property we now "wrap" the listing that is the actual "payload" of this Transfer File (all the above is necessary overhead). The rdf:parseType="Literal" is being used for that.
When this Transfer File is being parsed, this 'content' can simply be fetched and converted to quads in the Data section of the receiving façade. This is a task of the populate API method.

This is the template instance "vessel V-6060 is classified as horizontal vessel", as has been sent in the first transfer file from the ME03 application to its "me03" facade. It is now further shifted "up the information chain" to the "ves" facade. Note that it is completely unchanged |

Shorthand template instance ST-ves267723 is a member of an OIM specialization of generic template class ST-3401. The "temporalWhole" is defined in the Project Façade ("cons"), and referred here. The temporal part is defined here, on the fly. It shall not be explicitly declared. The (optional) "context" is some change order or the like. The information represented by this template instance began to be valid on January 20th 2008 at 10:05:00am "Zulu" time (= UTC, = GMT (give or take a few microseconds)). RDS658578 = Nominal Volume Capacity (faked ID, still) XSFL_60 is a (XML Schema)float of 60 RDS994572 = m3 (faked ID, still) |
