Are documents O3PO business entities? #1

Closed lbota closed 6 years ago

Notices, Call for Tenders, Tenders, Contracts, Orders, Invoices, etc....should they be conceptual entities (of the Conceptual Model) and therefore owl:Class(es) of the ePO Ontology?

CG says: Yes, as they carry data such as ' IssueDate,receptionDate,Language,Sender`, etc.

EST says: We should not mix "Document Metadata" with "data contained in documents". A Notice, Call for Tenders, Call for Proposal, Invitation to Tender, Contract, Order, Invoice, etc. are to be seen as "data conveyer (carrier) instances".

We want to propose using the IFLA-LRM ontology to represent them as "Works". Thus, the ePO would define epo:Notice (and subclasses "PIN", "CN", "CAN") as owl:SubClassOf lrm:Work.

We would like to discuss this with the OP's CELLAR team first, as they have produced a new CDM Ontology that reuses the ISA2's DCAT-AP Core Vocabulary as an abstract layer. We'll do it in Feb. 2018, hopefully.

This is being discussed in the Conceptual Data Model (CM) internal discussions, as part of its analysis and design. We should close this issue.
