16:37:44 <mhausenblas> PROPOSAL: For a foreign key of any arity, the reference property IRI is of the form <Table#ref-attr1-attr2-...-attrn>. This will address ISSUE-65

16:40:31 <mhausenblas> q?
16:40:33 <mhausenblas> q+
16:40:58 <mhausenblas> Eric: both '-' and '.' are technically allowed
16:41:57 <mhausenblas> ... the downside of the dot is that it can confuse with the schema (DB/table) identifier
16:42:58 <mhausenblas> ... the downside of the dash is that you'd need to escape the attribute value
16:43:02 <mhausenblas> q?
16:45:38 <ericP> -> http://www.w3.org/2001/sw/rdb2rdf/directMapping/explicitFK the dot variant
16:45:42 <mhausenblas> Eric: we can have both options in the DM document and ask for feedback
16:46:38 <ericP> http://www.w3.org/2001/sw/rdb2rdf/directMapping/explicitFK#defn-custom-url-encode
16:47:10 <MacTed> so this is an example --    pencil:_ <TaskAssignments#ref.project.deptName.deptCity> _:c .
16:49:06 <MacTed> vs                    --    pencil:_ <TaskAssignments#ref-project-deptName-deptCity> _:c .
16:50:43 <ericP> imo, <http://foo.example/Table/attr1=value1,attr2=value2> is intuitive
16:51:11 <ericP> <http://foo.example/Table/attr1.value1-attr2.value2> is easy to abbreviate with prefixes in turtle, SPARQL, RIF,...
16:51:51 <ericP> <http://foo.example/Table/ID.-5>
16:52:23 <ericP> <http://foo.example/Table/attr1.value1.attr2.value2>
