Remove redundant date time parameters

[junrongYu]

There are 31 date time parameters in DAWE vocabulary, but some can be replaced by TERN Ontology classes (end search can be prov:endedAtTime), some cannot (search time - it is a duration parameter). We are not sure which one protocols team want to preserve.

Here all date time parameters can be fetched by the following steps:

1. Open https://graphdb.tern.org.au/
2. Select repository as dawe_vocabs_core
3. At the left-hand side category, select SPARQL
4. Run the query

PREFIX tern: <https://w3id.org/tern/ontologies/tern/>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
select ?moduleLabel ?parameterLabel ?definition ?type {
    ?module skos:member ?parameter ;
            skos:prefLabel ?moduleLabel .
    ?parameter tern:valueType ?type ;
               skos:prefLabel ?parameterLabel ;
                skos:definition ?definition .
    filter (?type in (tern:DateTime, tern:Date))
}
order by ?parameterLabel

There are some duplicated parameters in the result because they are used in different modules or submodules. 1st column shows which module this parameter belongs to, e.g. Fire Attributes means the parameter is in the protocol Fire. 2nd column is the parameter name, 3rd column is the parameter definition, 4th column is the parameter type, Date or DateTime.

Date is https://linkeddata.tern.org.au/viewers/tern-ontology?uri=https://w3id.org/tern/ontologies/tern/Date DateTime is https://linkeddata.tern.org.au/viewers/tern-ontology?uri=https://w3id.org/tern/ontologies/tern/DateTime

From meeting: use prov start and end time properties

duration - do we really need it since we already know the start and end time

This is the list of date time attributes:

Hi @edmondchuc , could you please have a look at the above table? Here, all the data and time related attributes are listed and I think all of them can be replaced by prov start and end time properties, except for those bold one.

[edmondchuc]

Hi @junrongYu, prov:startedAtTime and prov:endedAtTime are the date time values of the start and end of activities. Therefore, I think it's only applicable to the ones such as "survey start datetime" and "survey start time". The other ones like "recovery date" and "date of pan trap establishment" I think are not applicable.

[junrongYu]

Hi @edmondchuc ,thanks! How about these attributes, are they like start and end time?

datetime	The date and time of the active search of invertebrate sampling (auto recorded).	tern:DateTime

leaf-litter sampling date	The date of leaf-litter sampling	tern:Date
leaf-litter sampling time	The time of leaf-litter sampling	tern:DateTime

observation datetime	The date and time when observation/s were made.	tern:DateTime

[edmondchuc]

Yeah they look suitable.

[junrongYu]

Cool thanks! For these attributes, do we just delete them all?

[edmondchuc]

I think so, as long as we don't lose information. For example, the first one, datetime - The date and time of the active search of invertebrate sampling (auto recorded)., in a Sampling activity, we specify the start and end time with prov:startedAtTime and prov:endedAtTime and for the "active search of invertebrate sampling" part, we express that by linking to the correct method via the property sosa:usedProcedure. So looks like should be fine to delete them since all the information will be retained properly.

[junrongYu]

and for the "active search of invertebrate sampling" part, we express that by linking to the correct method via the property sosa:usedProcedure

Hi @edmondchuc , will sosa:usedProcedure be designed in the App? Or should we add it to our vocabulary now? like add it to the attribute or property concept, metadata for properties etc.

[edmondchuc]

If you look at tern:Sampling or tern:Observation, you will see there's a property on the class called sosa:usedProcedure. This is defined in SOSA, see https://www.w3.org/TR/vocab-ssn/#SOSAusedProcedure.

Thanks! I understand now. I'll delete these attributes.

Attributes to be deleted:

datetime, end search, leaf-litter sampling date, leaf-litter sampling time, observation datetime, start search, survey start datetime, survey start time, survey end time.
