  Numerous ontologies include richer relationships that can be used for this purpose, at various levels of domain-specificity.  For example, the use of skos for terminologies (e.g. exact matches), or the use of SIO for genomics (e.g. 'has phenotype' for the relationship between a variant and its phenotypic consequences).  The semantics of the relationship do not need to be 'strong' - for example, 'objectX  wasFoundInTheSameBoxAs objectY' is an acceptable qualified reference
 
  Similarly, dbxrefs must be predicated with a meaningful relationship  what is the nature of the cross-reference?
 
  Finally, data silos thwart interoperability.  Thus, we should reasonably expect that some of the references/relations point outwards to other resources, owned by third-parties; this is one of the requirements for 5 star linked data.""" ;
