SPARQL queries and work with RDF in general requires uses the concept of a short prefix string representing a URI to resolve an identifier. Prefix declaration in a query lets us use the short strings in place of constantly putting in a fully qualified and resolvable path. The wikibase.cloud folks have taken the stance that prefixes should always be explicitly declared as opposed to being in the default configuration for queries, which is good practice but a bit of a pain. Here is a rundown of the full set of prefixes for this Wikibase instance. You'll see the applicable prefixes from this exhaustive list in the query examples.
SPARQL queries and work with RDF in general uses the concept of a short prefix string representing a URI to resolve an identifier, creating the ability to refer to different resolvable knowledge representations with a short string. Prefix declaration in a query lets us use the short strings in place of constantly putting in a fully qualified and resolvable path. The wikibase.cloud instances all use a standard set of built-in prefixes and resolvers, some of which are well known and in common use.
 
They also include the standard wikidata prefixes referring to Wikidata resolution paths. Initially, in this Wikibase instance, we were documenting queries in a way that might be confusing in that we use the same standard "wd" prefixes but declared them as this Wikibase. We've since changed that convention, but you may still find references that point to the older style than the conventions shown below.
