NFDI4Ing Terminology Service (TS)

[Ludee]

Description of the issue

Dear OEO authors we are pleased to inform you that we have successfully added your Open Energy Ontology to our NFDI4Ing Terminology Service. Our aim is to bring together your and other ontologies from the broad field of engineering and make them easily accessible to interested communities for use and further contribution and curation. Potential users of their ontology can thus search, browse and visualise matching entries. Furthermore, we provide a machine-readable interface (REST interface) through which these ontologies can be automatically queried and integrated into third-party applications. An example of the latter is our browser plugin TermClick, which already queries their and other ontologies from our service ad hoc.

In order to improve the discoverability of the Open Energy Ontology, we would like to ask you if you could classify your ontology for us with regard to the DFG classification? You are welcome to choose more than one suitable entry. Among others, some sub classes of the entry Energy Process Engineering might be already relevant for you?

Ps: Please feel free to forward this email to your colleagues. Please do not hesitate to contact us with questions, suggestions or criticism. PPS: We now also have a LinkedIn account to keep you up to date with the latest news. It would be nice to welcome you there

I checked the entry of the OEO and most of it seems correct. There are some minor issues I want to address:

1. Version How do we communicate and update the latest version?

2. VersionIRI We can link to the latest version: https://openenergy-platform.org/ontology/oeo/releases/oeo-full.owl We can link to specific versions like: http://openenergy-platform.org/ontology/oeo/releases/1.15.0/oeo.owl The page https://openenergy-platform.org/ontology/oeo/releases/ exists but doesn't work as expected!

3. Creator akleinau et al Use OEO Developers or the citation.cff

4. Is SKOS What does that mean? Link: https://www.w3.org/2004/02/skos/

5. DFG classification

Ideas of solution

1. Ask TIB
2. Rename oeo-full.owl to oeo-latest.owl or http://openenergy-platform.org/ontology/oeo/releases/latest/oeo.owl Create the page https://openenergy-platform.org/ontology/oeo/releases with all releases listed!?
3. All Contributors are listed under additional information
4. Who knows this?
5. The Repo https://github.com/tibonto/dfgfo doesn't exist https://github.com/tibonto/DFG-Fachsystematik-Ontology and https://terminology.nfdi4ing.de/ts/ontologies/dfgfo work Suggestions:

• dfgfo:407 "Systems Engineering"
• dfgfo:408-03 "Electrical Energy Generation, Distribution, Application"
• dfgfo:409-02 "Software Engineering and Programming Languages"

2. Rename oeo-full.owl to oeo-latest.owl or http://openenergy-platform.org/ontology/oeo/releases/latest/oeo.owl

Why renaming this file? oeo-full.owl and oeo.owl are different files. oeo-full.owl contains everything in one file while oeo.omn is a conversion of oeo.omn.

3. Use OEO Developers or the citation.cff

Or the part of the dc:contributor annotations which is not in parentheses.

5.DFG classification

It is hard to classify the OEO in this structure of disciplines as our domain is orthogonal to this structure. In my view the OEO does not fit properly in any of the categories. A key characteristic of our domain is not digging deeper and deeper in one specific topic but working inter- and transdisciplinary by combining the results various disciplines depending on the research questions and providing overarching insights. Keeping that in mind, I would also add the following to the list:

• dfgfo:42 "Thermal Engineering/ Process Engineering"
• dfgfo:112-02 "Economic Policy, Applied Economics"
• dfgfo:313 "Atmospheric Science, Oceanography and Climate Research"

There are some minor issues I want to address:

1. Version How do we communicate and update the latest version?

Seems like the version is updated automatically and linked under "VersionIRI". Is there a need to change that?

[l-emele]

If I remember correctly, the IRI http://www.openenergy-platform.org/ontology/oeo/oeo.owl redirects to the latest release.

@MGlauer : Can you confirm?

[MGlauer]

@adelmemariani is probably the right person to ask here.

The ontology IRI for the ontology should always resolve to the most recent release version. http://www.openenergy-platform.org/ontology/oeo/

If a specific version is needed, one has to use the respective VersionIRI http://openenergy-platform.org/ontology/oeo/releases/[version]/oeo.owl

[l-emele]

As far as I can see, the NFDI4Ing Terminology Service uses always the latest OEO version. At least, it is currently at version 2.4.0:

So is there anything left open from this issue or can we close it?

In OEO-DEV #112 we decided to add the OEO Developer Group and a link to the citation file.

Are these imports up to date?

"importsFrom": [
    "skos",
    "stw",
    "uo",
    "prov",
    "ro",
    "iao",
    "dcterms",
    "bfo",
    "obi",
    "stato"
],

I created an updated version of the metadata file of the TS

2025-12-05_oeo_metadata.json -> new version below!

In OEO-DEV #112 we decided to add the OEO Developer Group and a link to the citation file.

We never use the term "OEO Developer Group", instead we use "OEO Developer Team" in any context. Someone changed this in the Etherpad to "Group". Let's stick to "Team" please! @Ludee @amanda-wein @UStucky @b-gehrke @schwarzatoffis

I created an updated version of the metadata file of the TS

2025-12-05_oeo_metadata.json

Where does this file come from? Is it in the Repo? EDIT: found it on the TS page

[Ludee]

Yes, I downloaded it from the TS page to see the structure and data types.
