Hi Richard,

Adding back in the SKOS list directly! Thanks for your reply- copied
below for the list. Makes sense re attributes/markup, and to use
explicit markup not support code. But I don't know much about the
'dir' attribute - which namespace if any that it is in, etc. From an
RDF/XML perspective, SKOS that uses it would need to use XML Literal
markup, I guess? I'd be really happy if someone from this list put
together a short best practice guide for SKOS at the modelling level,
and SKOS at the syntax (RDF/XML, RDFa, Turtle...) level. Ideally some
SPARQL queries too...
