Create class for household identifier

[aellenhicks]

Proposed definition by @zhengj2007 in issue #62

household identifier: A symbol that denotes a specific household. (parent: IAO_0000028 symbol)

[aellenhicks]

Created a class in devel branch. (OMRSE_00000143)

Uses the above definition and as the following equivalence class restriction:
symbol and denotes some household
Where household is defined in OMRSE as:
A human or collection of humans that occupies a housing unit by storing their possessions there and habitually sleeping there thereby participating in the realization of its residence function.

Is this what you need?

[zhengj2007]

Yes it is.

However, current we are using PCO: 'household' in our application ontology. Could OMRSE work with PCO to decide keep one of 'household'? Thanks!
