Relationship between "time series" of the OEO and "time sampled measurement data set" of the IAO

[ap-peh]

Description of the issue

At the moment, the IAO (Information Artifact Ontology) is only partially imported into the OEO. In the definition of the entity "time series" it is indicated under "may be identical to" that "time series" may express the same as the entity "time sampled measurement data set" of the IAO. I would not see it that way. The definition of the entity "time sampled measurement data set" indicates that it is an ordered list of "time measurement data" and the associated "measurement data". The entity "time series" of the OEO on the other hand gives the possibility to add information like the resolution, the license or the start time. I would consider this as further meta information of the time series.

Ideas of solution

The entity "time sampled measurement data set" of the Information Artifact Ontology could become part of the entity "time series" via a property (maybe a new property). So then the properties "has measurement datum" and "has time stamp" of the IAO could be used to add timestamp and value.

Workflow checklist

• [ ] I discussed the issue with someone else than me before working on a solution
• [ ] I already read the latest version of the workflow for this repository
• [ ] The goal of this ontology is clear to me

I am aware that

• [ ] every entry in the ontology should have a definition
• [ ] classes should arise from concepts rather than from words

time sampled measurement data set connected with time series via a property

Connecting entity „time series“ (http://openenergy-platform.org/ontology/oeo/OEO_00030034) via property „has part“ (http://purl.obolibrary.org/obo/BFO_0000051) with entity „time sampled measurement data set” (http://purl.obolibrary.org/obo/IAO_0000584) for the entity „time sampled measurement data set” the following things from the IAO.

• Entity "time stamped measurement datum” (http://purl.obolibrary.org/obo/IAO_0000582)

Adding Identifier to entity “time series” / and all sub entities

• Entity “identifier” (http://purl.obolibrary.org/obo/IAO_0020000) via property “has part”

It was suggested to import measurement datum which is defined as: A measurement datum is an information content entity that is a recording of the output of a measurement such as produced by a device. We already have quantity value defined in the OEO: A quantity value is an information content entity defined by a numeral together with a unit of measurement to quantify an entity. So there is at least some overlap between those two and what is the relation between those? Is a measurement datum a quantity value that was determined (measured) using some measuring device?

A quantity value and a measurement datum are very similar, that's correct. But we need a possibility to connect a measurement_datum (or a quantity_value) to a specific Timestamp. The time_series in OEO contains only Timestamps / Timespans, but no reference to the corresponding measured values. So a data_set / time_series / time_sampled_measurement_data_set with a Timestamp and a Measured Datum in every step is needed.
