Extraction with robot not working
Opened this issue · 9 comments
Dear All,
I am trying to extract some concepts of this ontology using robot. I found two files in this repository, those are: om-2-ucum.ttl and om-2.0.rdf.
With them, I edited the following commands:
robot extract --method STAR --input source_ontos/om-2-ucum.ttl --term-file onto_terms/om2_terms.txt --output extracted_modules/om2_start.owl
robot extract --method STAR --input source_ontos/om-2.0.rdf --term-file onto_terms/om2_terms.txt --output extracted_modules/om2_start.owl
Obtaining the following results:
After that, I decided to save both ontologies as owl files, using protege, but the result of this command:
robot extract --method STAR --input source_ontos/om-2-ucum.owl --term-file onto_terms/om2_terms.txt --output extracted_modules/om2_start.owl
was exactly the same as the first picture, and the result of applying the extraction command on file om-2.0.owl was the following:
to summarize robot (as protege) does not find any ontology in:
http://www.ontology-of-units-of-measurement.org/resource/om-2/
So, I wonder how to solve this issue?
I am also curious to know if you have an .owl version of this ontology, because I only found .ttl and .rdf.
Best regards
Luis Ramos
Hi Luis,
Thanx for your issue.
First of all: the link you use (http://www.ontology-of-units-of-measurement.org/resource/om-2/) is not correct. It should be: http://www.ontology-of-units-of-measure.org/resource/om-2/
Second, the screenshots of your error messages unfortunately are unreadable. Could you perhaps give the messages in some other way or using sharper screenshots?
Thanx in advance, and of course I hope that my first point already helps! :)
Cheers, Hajo
The underlying issue could be that it is not possible to retrieve the ontology without a browser:

@luisenriqueramos1977 , sorry I overlooked your last question:
I am also curious to know if you have an .owl version of this ontology, because I only found .ttl and .rdf.
No we only have an rdf version.
@BonaBeavis , thanx for your comment.
Not sure how we can solve this... Have to think about it, ask round.
What happens if you would use http://www.ontology-of-units-of-measure.org/page/om-2/ ?
Best, Hajo
With http://www.ontology-of-units-of-measure.org/page/om-2/
wget only gets a html page.
Here is a guide how to solve this: https://www.w3.org/TR/swbp-vocab-pub/
Thanx for trying. Indeed, that's not the result we want.
I have raised the topic to a colleague of mine, along with the valuable link you give.
To be continued.
A colleague of mine is looking for ways to organizing solving this problem.
We are also discussing the problem itself. Could you perhaps try http://foodvoc.org/resource/om-2?
Same thing.

Thanx. One never knows. Unfortunately it didn't help.
To be continued with my colleague.
