Try this:
\define dropbibtex()
<$wikify name="source" text=<<actionTiddler>>>
<$set name="source"
filter="[<source>removeprefix[@book{]removesuffix[}]split[,]rest[]join[,]]"
select=0>
<$list filter="[<source>split[}]first[]trim[]removeprefix[title={]]"
variable="title">
<$list filter="[<source>split[}]]" variable="item">
<$vars f={{{ [<item>split[={]first[]trim[,]trim[]] }}} v={{{
[<item>split[={]rest[]trim[,]trim[]] }}}>
<$action-setfield $tiddler=<<title>> $field=<<f>> $value=<<v>> />
</$vars>
</$list>
</$list>
</$set>
</$wikify>
\end
<$droppable actions=<<dropbibtex>>>
<$button style="width:10em;height:10em;">drop bibtex here</$button>
</$droppable>
Notes:
* $wikify converts the dropped content into plain text, removing any
surrounding HTML syntax
* $set removes the leading "@book{", trailing "}" and first value (e.g.,
"crary2016inside")
* first $list extracts the target tiddler title value from title="..."
* second $list extracts each named item (e.g., author={Crary, Alice)
* $vars gets the fieldname (everything before the "={") and fieldvalue
(everything after the "={") from the item
* $action-setfield creates each field and value in the target tiddler
enjoy,
