“ As an illustration, the 'author' field in the infobox is coded like this:
| label2 = Author{{#if:{{{authors|}}}|s}} | data2 = {{#invoke:WikidataIB |getValue |P50 |name=author |fetchwikidata={{{fetchwikidata|}}} |suppressfields={{{suppressfields|}}} |{{{authors|{{{author|}}}}}} }} The property to be fetched is the first unnamed parameter. In this case it is author (P50) .
The name of the field is passed in |name= and that name is checked against the blacklist and the whitelist. To always suppress the author field in a particular article, an editor will set |suppressfields=author in the infobox. ”

“ If there is a sitelink to an article on the local Wiki, it returns the sitelink as plain text, otherwise nothing getSiteLink gets the plain text link to an article on a given wiki getLabel returns the Wikidata label for the local language as plain text. If there is no label in the local language, it returns the entity-ID getAllLabels fetches the set of labels and formats it for display as wikitext labelorid returns the label with all wikitext removed, or the entity-ID if no label getDescription returns the article description for the Wikidata entity if the local parameter is "Wikidata". ”

“ The coordinates from Wikidata are parsed and passed to Template:Coord which returns the display as if it were called manually. The blacklist of fields that are never to be displayed, and the whitelist are implemented in the same way as for getValue using |suppressfields= and |fetchwikidata= The format parameter sets the display format to decimal or dms. Any value beginning with "dec" sets decimal; anything else sets dms. The display parameter sets the display position to "inline", "title" or "inline, title". Default is nothing (so uses default for {{Coord}}, currently "inline") . ”

“ For example, one field may set |list=hlist where a series of short words is expected; whereas another field could use |list=ubl where an unbulleted vertical list of several words on each line is required. ”
