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.
8 +
9 +Mappings are available in the ontology by three types of RDF statements. See [[section on RDF>>doc:SPARQL-endpoint]].
10 +
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:

14 +
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, which must be passed as a CSV file. This CSV file must be set up in a particular way.
20 +
21 +The following resources are available.
22 +
23 +* [[Upload facility for CSV files>>url:||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.
24 +* [[Documentation of how to create a mapping>>url:||rel="__blank"]] (PDF, in Dutch).
25 +* [[Documentation on how to introduce context information info the CB-NL>>url:||rel="__blank"]] (PDF, in Dutch).
