SDM-RDFizer not able to semantifying rml mapping rules files with join conditions for accents characters

[rohit252]

snap 1 snap 2 snap 3

SDM-RDFizer not creating triples for the above rml file with the join condition, here author_1.csv file contains first, last and institution name with the accents characters but when I create another csv file author_2.csv without the accent characters but with the same content as author_1.csv it is working then.

I have created a test case:

SDM-RDFizer.zip

1. After unzipping the folder, Inside the SDM-RDFizer folder there is a folder named "exam" , in the exam folder we have three csv files, rml mapping rule file and config file for the SDM-RDFizer.

2. author_reference.csv file contains id and author_id, I have used this csv file in the triplemap 1 as we can see in the above snap1.

3. author_1.csv file contains first, last and institution names with the accents characters and I am using join conditions to join triple map1 and triple map2 ( please see snap 2 )

4. After running the config file for the SDM-RdFizer, I am getting the error, please see snap3

5. But using author_2.csv if I do the same steps, then it is able to generate n triples.

Please see pics:

Hello @rohit252,

First of all thank you for using the SDM-RDFizer. Coincidentally, I was working on the reading of special characters. I fixed the problem. I ran the example you sent me I ran with no problem. Here is a portion of the resulting nt file.

Keep in mind that I only updated the code, not the library. Please test it out and tell me if the problem was solved on your end. Afterwards, I will update the library.
