Consider: subclasses of data

the following suggestions to be discussed as alternative modelling approaches:

the following classes could be set as sub-classes of data:

• edge(HDO_00000017) definition "A connection of nodes in a graph."@en
  • alternative definition: data which connects nodes in a graph
• ontology (HDO_00000033) definition "A representational entity which uses a formal language to model knowledge by defining entities (classes) and declaring the logical relationships between them (relations)."@en
  • altenative definition: data which represents knowledge by using a formal language to define entities (classes) and declaring the logical relationships between them (relations). (this would probably get annotation of "hasOntologicalStructure" according to discussion in #40 (closed))
• ordered pair (HDO_00001032) definition "An object which contains exactly two elements in a fixed order."@en
  • alternative definition: data which consists of exactly two elements in a fixed order

the following classes could be set as sub-classes of data set:

• vocabulary (HDO_00002008) current definition "A collection of terms."@en
  • alternative definition: "A data set which consists of a collection of terms"
