QUESTION
I am trying to use FnO functions in RML mapper (I like to do a string_split
like here).
This is how my folder looks like:
I am executing java -jar "rmlmapper.jar" -m mapping-cuisines.ttl -o output-cuisines.ttl -s turtle
However, when I try implementing a <#FunctionMap>
i get the following error message:
ANSWER
Answered 2021-Mar-17 at 15:39I tried out your mapping file and it works correctly.
Your current mapping file transforms the data in the spicy
to upper case
and generates the specified RDF triples.
Since the function grel:toUpperCase
is included in the RMLMapper by default,
you don't need to functions.ttl
to specify these functions.
This is only necessary if you want to add your own custom functions.
An overview of all included functions in the RMLMapper can be found here: https://rml.io/docs/rmlmapper/default-functions/
- Download the latest RMLMapper from our Github repository: https://github.com/RMLio/rmlmapper-java/releases
- Run it as:
java -jar -m mapping.rml.ttl
- I get the output which is listed below.
mapping.rml.ttl

I want to recieve the time in seconds between the two runs where I type y
in the python shell.
I am sorry earlier I did not specify what I want it to be. Basically this is the program I am testing to implement in another big program (bigger than this one).
Here is what I want the output to be:
First I will run the program and it will ask if I want to borrow and I will click y
.
After that I will run the program again and it will ask me to return, again I will click y
and it should return the time in seconds for which I borrowed. the cycle will continue.
This is the program which I need for a library management system.
