 3: Mappings are formal relations between concepts in a client system and those in the CB-NL. For example ,"Bruggen (beweegbaar)" may be specified to be the same as "Beweegbare brug". There are three kinds of relations:
 4: 
 5: * **same as**. Two concepts are actually the same, but are described differently.
 6: * **subtype of**. The concept in the context ontology is a subtype of a concept in the CB-NL. The concepts are clearly related and some computational decisions can be drawn from this relation. 
 7: * **related to**. There is a clear relation between two concepts but this is not based on identity or type. This is a weak descriptor and no computational decisions can be drawn from it. However, for human interaction this may be a relevant relation.

 9: Mappings are available in the ontology by three types of RDF statements. See [[section on RDF>>doc:SPARQL-endpoint]].

11: Mappings are displayed in the viewer. This takes the form of a relation type, a set of context names, and links to context concepts. For example, for "pump" the following context mapping are available:

15: By clicking on any context link (such as NEN2767-4: Pomp) the information available on that concept is shown.

19: Context owners may supply a mapping to the CB-NL team. For this, the team requires a formal description of this mapping. There are two ways of supplying this formal description. 
20: 
21: The first method requires the mapping to be uploaded as a CSV file. This CSV file must be set up in a particular way.
22: 
23: The following resources are available for this method:
24: 
25: * [[Upload facility for CSV files>>url:http://mapper.cbnl.org/upload||rel="__blank"]] (external link). This checks the contents and returns a ZIP file with the processed results, that can be passed to the CB-NL team for introduction into the CB-NL.
26: * [[Documentation of how to create a mapping>>url:http://mapper.cbnl.org/xslweb/CBNL-Mapper/html/data/20150223%20Mapping%20maken%20voor%20CBNL.pdf||rel="__blank"]] (PDF, in Dutch).
27: * [[Documentation on how to introduce context information info the CB-NL>>url:http://mapper.cbnl.org/xslweb/CBNL-Mapper/html/data/20150217%20Mapping%20in%20viewer.pdf||rel="__blank"]] (PDF, in Dutch).

29: The second method is to use a separate mapping tool (user interface in Dutch), which can be found here: [[http:~~/~~/mappingtool.cbnl.org>>url:http://mappingtool.cbnl.org/]]/.
