CLI for Turtle Pretty-Printing (or general conversion between RDF serialization formats)

[hoijui]

I am currently evaluating different possibilities for Turtle pretty-printing, and would like to include RDF4J.
I could just write-up a tiny CLI using RDF4J for Turtle re-formatting myself, but wanted to ask if there is already something out there, so there could be more collaboration and less duplication.

Hi! Not sure about RDF4J, I'm not a maintainer here... But here's what I know of:

• Apache Jena Commands distribution includes the riot command that can convert between basically any common RDF format: https://jena.apache.org/download/index.cgi
• My jelly-cli tool is also built on Jena and is specifically optimized to work with the Jelly format (super-fast RDF serialization), but can also work with other formats: https://github.com/jelly-RDF/cli
• There is also ld-cli which is built specifically for JSON-LD and CBOR-LD formats: https://github.com/filip26/ld-cli

I've used all of these and they work great. :)

Note: jelly-cli and ld-cli offer pre-compiled binaries with very fast startup (GraalVM Native). The riot command has slower startups, but you could probably hack it to work with Graal with some effort.

I knew only about Apache Jena and riot of the ones you mentioned. will check-out the others!

• There is also the library turtle-formatter (based on Apache Jena) and owl-cli (based on turtle-formatter).
• A Rust alternative is turtlefmt.
• Some C alternative(s) can be found int the librdf ecosystem, specifically in raptor (CLI RDF serialization conversion tool).

Thanks! That's useful to know.

If you want to work with OWL, then there is also ROBOT: http://robot.obolibrary.org/

But it's less about RDF, and more about ontologies.

That is a big part of what I need it for, thanks!

The script `console.sh` that is provided in the eclipse SDK download has a convert utility.

A bit hefty ... but will try, thank you! :-)
