The cjconsensus Gold-Standard data set contains the following AMR (from a sentence in the results section of Innocenti et al. 2002):
# ::id pmid_1177_7939.53 ::date 2015-03-07T10:57:15 ::annotator SDL-AMR-09 ::preferred
# ::snt Sos-1 has been shown to be part of a signaling complex with Grb2, which mediates the activation of Ras upon RTK stimulation.

(s / show-01
:ARG1 (h / have-part-91
:ARG1 (m / macro-molecular-complex
:ARG0-of (s2 / signal-07)
:part (p2 / protein :name (n2 / name :op1 "Grb2")
:ARG0-of (m2 / mediate-01
:ARG1 (a / activate-01
:ARG1 (e / enzyme :name (n3 / name :op1 "Ras"))
:condition (s3 / stimulate-01
:ARG1 (e2 / enzyme :name (n4 / name :op1 "RTK")))))))
:ARG2 (p / protein :name (n / name :op1 "Sos-1"))))
Under our current rubric, this would then be translated to the following RDF TTL code, with a fairly simple one-to-one mapping from AMR elements to RDF elements.

This is a simple script that reads the AMR using libraries from the AMRICA toolkit and then transposes the graph structure of the AMR into RDF using rdflib. We use simple heuristics to map namespaces and to generate valid RDF for the AMR as needed.
How to run the script:
$ python amr_to_rdf.py -i <input AMR file> -o <output RDF file> [-f <format>]
How to test the script:
$ python amr_to_rdf.py -i test/bio_ras_0001_1.txt -o out.rdf -f nt
