Every format holds the same triples. The Turtle is the converter's output, and the others are translated from it. The IRIs are placeholders until a persistent home is agreed.

Single resources

Every element, isotope and declaration has its own page and Turtle file, and its IRI opens that page. For example, the page of hydrogen-1 links to H-1.ttl. GitHub Pages cannot choose a format per request, so software should add .ttl to an IRI, or read the <link rel="alternate"> of the page.

Mappings

ciaaw.sssom.tsv maps the elements and isotopes of the current data to their Wikidata items (skos:exactMatch, matched on atomic number and number of neutrons) and to ChEBI (skos:closeMatch). It is an SSSOM mapping set in the TSV serialisation: a YAML header in comment lines, then one mapping per row. The license (CC0) covers the mappings only, not the CIAAW values.

Revision example

A small sample after an invented revision of hydrogen. See the revision example.
