8 years ago The things which concerns me is the JSON. As such, I've run example3 (https://github.com/RMLio/RML-Processor/tree/master/src/test/resources/example3) from RML Examples you gave me,
In this example (example3), it gives a mapping file example3.rml.ttl and a sample output from this mapping file example3.outpu1.ttl
I've performed the RML Mapping with the same mapping file example3.rml.ttl using the command "java -jar rml-mapper.jar -m example3.rml.ttl -o example3.output1.ttl".
The output file example3.output1.ttl is completely different from the given output example3.output.ttl though the very same mapping file has been used with the same sources.
In fact, no tripples is being generated from the VenueMapping trippleMap whose source is a json

8 years ago Firstly, the examples you see are unit tests for the RML-Processor. That being said, the jar for the RML-Mapper can not be generated if the examples do not generate proper output. So, the example 3 returns the expected output so it is correct.
Moreover, I just tried it locally and using the command java -jar target/RML-Processor-0.2.jar -m /home/andimou/RML-Mapper/RML-Processor/src/test/resources/example3/example3.rml.ttl -o /home/andimou/RML/Output/norbakerally/example.ttl -f turtle
Could you copy-paste the exact command that you run?

8 years ago I understand that the generation cannot happen, but it's not generating the same output for me,
the command i'm using is java -jar /home/bakerally/Documents/tutorials/2016/rml/mapper/RML-Mapper/RML-Processor/target/RML-Processor-0.2.jar -m example3.rml.ttl -o example3.ttl -f turtle
You can see the generated output i'm getting at https://github.com/noorbakerally/rml-examples/blob/master/example3/example3.ttl which contains the exact example from the RML Processor,

8 years ago Would you like to try example 4? It's the same and let me know what's going on?

commented
8 years ago Example4 works fine but Example3 still doesn't work, The difference between Example3 and Example4 is the Input Source JSON Format, is there anything like it's tailored to a specific type of JSON Format ?

commented
8 years ago I noticed that example 3 is not included at the unit tests any more so consider it as deprecated. If example 4 works for JSON files, I think you have examples running for all three cases (CSV, XML, JSON).

8 years ago In the Specs, at the beginning, 3 examples were given, 2 of them are not working making it confusing how to operate systemically,
In the github repo at https://github.com/noorbakerally/rml-examples/blob/master/venue_example, I replicated the JSON example given at the beginning and run it with the command
java -jar /home/bakerally/Documents/tutorials/2016/rml/mapper/RML-Mapper/RML-Processor/target/RML-Processor-0.2.jar -m venue.rml.ttl -o venue.ttl -f turtle
It generated an empty file
In https://github.com/noorbakerally/rml-examples/tree/master/transport_example, it's the same example given for the transport xml at the beginning of the specs,
running the processor on the mapping file returns an empty turtle file with the command below: java -jar /home/bakerally/Documents/tutorials/2016/rml/mapper/RML-Mapper/RML-Processor/target/RML-Processor-0.2.jar -m transport.rml.ttl -o transport.ttl
So right now, I'm big confused about the problems and how it works, i went through both documentation R2RML and RML, if these example work, I can proceed systemically and clear I can the confusions
do you have an idea about the problems ?

8 years ago I don't know if there is a problem with the JSON conversion, but there is an example you provided in slide 21 at http://www.slideshare.net/andimou/dimou-rdf-mappinglanguage?related=1, I replicated the example here https://github.com/noorbakerally/rml-examples/tree/master/stock, this example is also not working and generating an empty turtle file
pheyvaer
I was going through the RML Specs and i tried the examples found at the beginning of the the Specs Document at http://rml.io/spec.html.
I created a small github repo for the examples at https://github.com/noorbakerally/rml-examples.
Status:
For the JSON example, I used the following command
java -jar RML-mapper.jar -m venue.rml.ttl -o venue.rdf
The commands executes and completes without any error. But the venue.rdf generated is empty. The output of the command is found below:
