• molgenis3_3 is not connected to svn (probably after helios installation) . molgenis4pheno is working.
• New molgenis project in molgenis4phenotypeWorkspaceHeliosCocoa32 with name molgenis ...and it's working with molgenis4pheno

External Ontology

(see relative message including Pedro Lopes, Richard Cyganiak)

• === How to connect multiple semantic systems, some using ​D2R and some purely semantic : ===

• learn basics of D2RQ mapping language, modify the mapping file that you probably created using generate-
  mapping. This is probably the file that lives in molgenis_distro (generated by d2rq) : WebContent/WEB-INF/molgenis-rdf-mapping.n3

• === For instance how to define mappings that explicitly say that a table column corresponds to an element of the FOAF ontology ? ===

• In the mapping file there is a class map corresponding to each table . Find the right class map . below the class map ,there is a property bridge for each column .

• Find the right class map. Below the class map, there's a property bridge for each column. Find the right one.
• Change its d2rq:property value to the FOAF term, e.g., foaf:name.
• You also have to make sure that the FOAF namespace is declared in the @prefix section at the very beginning of the file.

• === When there is a table column whose values map elements from the DailyMed D2R database? ===

• Instead of mapping the column to a literal with d2rq:column, use a d2rq:uriPattern that produces URIs that match the URIs in the other dataset.

next todos:

• Change its d2rq:property value to the FOAF term, e.g., foaf:name.
• You also have to make sure that the FOAF namespace is declared in the @prefix section at the very beginning of the file. *
