Oops! Fortunately, this is an IAU error, not mine (though you'd think I might have caught it). I replaced the BT with a RT radio_frequencies.

Yup - forgot the # all right. Corrected: now looks like

	<skos:Concept rdf:about="#53_Persei_stars">
		<skos:inScheme rdf:resource=""/>
		<skos:prefLabel>53 Persei stars</skos:prefLabel>
		<skos:broader rdf:resource="#B_stars"/>
		<skos:broader rdf:resource="#pulsating_variable_stars"/>
		<skos:definition>53 Persei stars</skos:definition>
	</skos:Concept>

Got those too. In the meanwhile, I've found various capitalization errors and stuck in some missing stuff for galaxy rotation curves (e.g. "Navarro-Frenk-White_profiles" anybody?).

Thanks for the corrections. Please keep them coming so that we can get this finished as a reasonable and reasonably complete (for our intial purposes only, of course) suggestion.

Douglas implicitly raises a good point: the text file isn't much simpler than n3 and n3 is a lot less verbose than SKOS/OWL - should the IVOA suggest vocabularies are published in n3?
