⚇ ddot.it Relations

Some relations are so commonly used, we suggest some standard names here:

Name	Aliases	Semantics (A .. relation .. B)
`related`	`rel`, `is related`	Undirected link connecting A and B.
`same as`	`is same as`	A and B are referring to the same concept.
`is alias of`		Like `same as`, but with a clear main concept. This is like a sym-link.
`links to`	`link`, `see also`	Directed, untyped link from A to B. Default link type when four dots (`....`) are used.
`has tag`	`tag`	A has the tag B. Tags are not transitive.
`has type`	`type`, `is a`	A has the type B. Like rdf:type. Types are inherited via `has subtype`.
`has subtype`	`subtype`	The type A has a more specialised type B. Transitive relation. If it forms a cycle, all participants of the cycle are considered to be the same entity (`same as`).

prefix – When parsing a name like A:foo (starting with prefix an colon) the A: should be replaced by B. This is only needed for RDF processing. This processing is just a recommended way to interpret a ddot.it triple base. Not needed in non-RDF contexts.
