With regard to wikidata infoboxes, it is either
* that the usual technical APIs implemented as parser functions must be learned by every Wikipedian
* or that simple interwiki transclusions are entered via the emerging WYSIWYG tools for Wikipedia
With regard to the content of wikidata infoboxes, it is either
* that nothing is annotated -- all such (semantic web) queries are driven resolutely towards wikidata
* or that infobox triples are annotated via HTML/a -- article content can optionally have HTML/a markup
In short it is either
* no wikipedias can be considered part of the semantic web
* or all wikipedias stand at the center of the semantic web
