Announces vs. RefersTo

[csnyulas]

When mapping eForms to ePO, we encountered several situations where it was not clear, or not easy to define, when to use "announces" vs. "refersTo" properties to link procedure, lot, planned part, various roles and review objects to different type of notices. The problem had a reasonably clear solution when we dealt with only competition and result notices, but it got very difficult when we had to adopt our mappings to handle correctly the use of these properties for all these 7 notice types:

• epo-not:CompetitionNotice
• epo-not:ResultNotice
• epo-not:PlanningNotice
• epo-not:DirectAwardPrenotificationNotice
• epo-not:ContractModificationNotice
• epo-not:PreMarketConsultationNotice
• epo-not:CompletionNotice

We need help to specify precisely the correct property to use in case of all the above notice types, for the following field

field / node	"announces" property	"refersTo" property	related entity type
BT-04-notice	epo:announcesProcedure	epo:refersToProcedure	epo:Procedure

The table below shows which predicates to use

Hello I'm reviewing this table and I just want to confirm a few things. Are the URIs listed here the corresponding URIs for the columns in the table?

Notice Type	URI
PreMarketConsultation	epo:PreMarketConsultationNotice
Planning	epo:PlanningNotice
Competition notice	epo:CompetitionNotice
DAP	epo:DirectAwardPrenotificationNotice
Result	epo:ResultNotice
Modification	??? Maybe? epo:ContractModificationNotice
Completion	epo:CompletionNotice
Notice (fallback)	Fallback to Notices not listed above

Could you kindly update these names to precise prefixed URIs for the corresponding concepts?

Also, I came across a property named preparesForPotentianProcurementObject. Is "Potentian" a typo? Should it be "Potential"?

If available, could you also point me to any documentation that explains what is the purpose of having different verbs?

Lastly, do all of these verbs inherit from epo:refersTo?

Many thanks !

Hi,

• Names were updated to the apropriate ePO classes.
• Cannot find the property preparesForPotentianProcurementObject in ePO 5.0.0, or ePO 4.2.0 Ontology or glossary. Can you specify where you found it?
• https://docs.ted.europa.eu/epo-home/REFumlconv2020.html#_relations
• No these verbs do not inherit epo:refersTo.

I see 'preparesForPotentianProcurementObject' in the image provided above, it's in yellow.

[AchillesDougalis]

I see, thanks for the catch.

I'm having trouble interpreting this table.

It shows that for the tuple epo:CompetitionNotice - epo:Reviewer, the verb is listed as N/A. However, when I look up the data in Cellar, I find that an epo:CompetitionNotice sometimes use the property epo:announcesRole to reference an epo:Reviewer.

Indeed, in the eForms, it is like that. Table updated.
