gcis:Project, Model as property #96

Closed justgo129 closed 9 years ago

justgo129 commented 9 years ago

Like https://github.com/USGCRP/gcis-ontology/issues/95 this is a spinoff of #12. Here, the turtle for models, in addition to projects, incorrectly uses classes as properties: https://github.com/USGCRP/gcis/blob/master/lib/Tuba/files/templates/model/object.ttl.tut

Example with instance data: http://data.globalchange.gov/model/ccsm3.thtml

I was unable to locate a candidate "property" relating a model to a Project like CMIP5 within dbpedia.

Similarly with relating a model run to a model: https://github.com/USGCRP/gcis/blob/master/lib/Tuba/files/templates/model_run/object.ttl.tut

To verify, we are looking for a property to relate reference a project instance from a model instance.

What are the semantics here? Did the project create the model, use the model, something different?

justgo129 commented 9 years ago

As an example, we're trying to relate ccsm3 (model) with CMIP3 (project), and vice-versa. I'd say the model is part of the project (okay, the running of the model is part of the project). I'm not sure dcterms:isPartOf or dcterms:hasPart would be adequate.

FYI, gcis:Project is a subclass of prov:Agent. Should I say a model can be used in many projects through model runs.

zednis commented 9 years ago

I do not think either dcterms:isPartOf or dcterms:hasPart are appropriate.

Also, our conceptual modeling here will be dependent on the resolution of #17.

If we resolve #17 with the addition of the class gcis:ModelRunOutput (subclass of prov:Entity) then we can use PROV to say that the ModelRunOutput was attributed to the Project (note: I am assuming we are wanting to say that the project created the model run output, not that they project has used the model run output to do something else)

justgo129 commented 9 years ago

Sounds good. I'll defer to the judgement of @rewolfe and @bduggan on this one.

justgo129 commented 9 years ago

Seeing no opinion to the contrary, please go ahead and perform the steps described in your latest comment, @zednis.

justgo129 commented 9 years ago

Also @zednis just as a point of information, this may also allow us to resolve #12, as the only other instances of that issue are visible at:

https://github.com/USGCRP/gcis/blob/master/lib/Tuba/files/templates/model/object.ttl.tut https://github.com/USGCRP/gcis/blob/master/lib/Tuba/files/templates/model_run/object.ttl.tut https://github.com/USGCRP/gcis/blob/master/lib/Tuba/files/templates/project/object.ttl.tut

Basically, the material relevant to the discussions of the relationships between a model, model_run, and project.

justgo129 commented 9 years ago

Now that #17 is resolved (thanks, @xgmachina), let's make the changes suggest by @zednis. We can then close this issue and #12.

justgo129 commented 9 years ago

@zednis when you get a chance please inform whether we close this issue. Thanks!

zednis commented 9 years ago

I believe this ticket is closeable.

justgo129 commented 9 years ago

Thanks, @zednis. Closed #96 given merged https://github.com/USGCRP/gcis/pull/235.
