Re: Progress toward making RDF easier?

This XSLT target will be considerably easier if you start with a nested RDF/XML than if you start with flattened TriX (or flattened RDF/XML for that matter).

If you want convenience, you want nesting; if you want completeness at the cost of more complex XSLT, you want a flat structure.

Agreed: my XML replicates the structural aspect of RDF/XML:

        </arc>
        <arc IRI="rdfs:label">

        </arc>
        <arc IRI="dcterms:description">
            <literal>Wordsworth's memorial. - Undated. - b/w postcard. - 88 x 138mm.</literal>
        </arc>
        <arc IRI="dcterms:title">
            <literal>Wordsworth's memorial</literal>
        </arc>
        <arc IRI="crm:P108i_was_produced_by">
            <node IRI="http://collections.wordsworth.org.uk/Object/WTcoll/id/1990.19.85.4/Production/1"<http://collections.wordsworth.org.uk/Object/WTcoll/id/1990.19.85.4/Production/1>/>
        </arc>
    </node>
so the XSLT transforms are no more complex than those starting from RDF/XML.
