ROSSETE RDF

This application is intended to convert the data stored in a database/CSV/JSON/XML/etc to RDF using a RML mapping file or list of them.

Note

If you find any issue or knows something that can be improved or added, feel free to create an issue in the github or contact me so it can be addressed.

Usage

To run this application, you need to run the following CLI command.

    rossete-rdf.exe [FLAGS] [OPTIONS] --output <OUTPUT> --MAPPINGS <MAPPINGS>

For more information, you can use the help flag (-h|--help). If you use it, the following prompt will appear with the possible custom usage options and others.

Rossete RDF Generator 0.1.0
Rubén Cid Costa
This application is intended to generate a rdf file from one or varios datasets in different formats and a RML mapping.

USAGE:
    rossete-rdf.exe [FLAGS] [OPTIONS] --mappings <MAPPINGS> --output <OUTPUT>

FLAGS:
    -w, --clear      Delete the database if it was created while reading the databases
    -h, --help       Displays this message
    -V, --version    Prints version information

OPTIONS:
        --config <FILE>          Sets a custom config file to create the main settings of the program
        --mappings <MAPPINGS>    Used mapping in the process of generated rdf. Values: Folder or a file
        --output <OUTPUT>        File name where the output file is written

The app doesn't work with maps with the same name. And it assumes that the following RML prefixes:

PREFIX	URL
rr:	http://www.w3.org/ns/r2rml#.
rml:	http://semweb.mmlab.be/ns/rml#.
ql:	http://semweb.mmlab.be/ns/ql#.

Example

In this repository, there is an example with the mappings that are used in the RML Documentation of the following link: LINK.

To run it, you can run the following command with the application:

rossete-rdf.exe --mappings ./examples/mappings --config config_example.json --output output.ttl

This command will create a Turtle File with the generated RDF.

Requirements

To use this executable, you need to install rust and cargo in your computer, so you can compile this repository. To check if you have them, use this commands:

   rustc --version  // To check if you have Rust Programming Language Installed
   cargo --version  // To check if you have Cargo Package Manager Installed

To compile it, you can use the following command in your terminal and you have Rust and Cargo Installed.

cargo build --release // This will create an executable in the newly created target/release folder

You can take the binary as a standalone binary and move it whereever you want to.
