Some people might find the N3 serialization useful.

It simply lists the subject, predicate and object followed by a period.

It is somewhat easier to interpret, and can be easy to make. You can even
create this with apps like FileMaker Pro.

You can then take this N3 form and convert it to RDF using online tools or
standard libraries.

Many if not most of the triple / quad stores can read in the n3 form

Here is an example that links a species concept to a geographical location.
(in both directions)
