[basex-talk] Request and JSON parsing

[Günter Dunz-Wolff]

Hi there,

via RESTXQ I request a vectorstore. The response is an JSON-Object.

For example:
With the following curl:
curl https://vector.io/query-data \
  -H "Authorization: Bearer ABcFMGhetc" \
  -d '{ "data": "Du hast dem Menschen ein so freies, herrliches und üppiges 
Leben bestimmt", "topK": 2, "includeVectors": false, "includeMetadata": true }'

I'm getting this object:

{
  "result" : [ {
    "id" : "ba02277",
    "score" : 0.9949091,
    "metadata" : 
{"genre":"ba","blatt":"1810-01","autor":"Kleist","titel":"Zoroaster.","link":"https://kleist-digital.de/etc","text":"freies,
 herrliches und üppiges Leben bestimmt."}
  }, {
    "id" : "ba01711",
    "score" : 0.8891792,
    "metadata" : 
{"genre":"ba","blatt":"1810-29","autor":"Ompteda","titel":"Fragmente","link":"https://kleist-digital.de/etc","text":"So
 mit dem Menschen im Moralischen."}
  } ]
}

1.
Is the request in my RESTXQ in the right form?
http:send-request(
        <http:request
            method="post"
            href="{$prod:url}/query-data">
            <http:header
                name="Authorization"
                value="Bearer {$prod:token}"/>
            <http:body
                media-type="application/json">
                {{
                "data": "{$query}",
                "topK": 20,
                "includeVectors": false,
                "includeMetadata": true
                }}
            </http:body>
        </http:request>
        )

2. 
I'm getting a full Object (but I dont know, if its the raw JSON-Object like 
above), but I am not able, to parse it, to get a list in html.
In the documentation https://docs.basex.org/wiki/JSON_Module is an example:
let $input := '{
  "Title": "Drinks",
  "Author": [ "Jim Daniels", "Jack Beam" ]
}'
let $data := json:parse($input, map { 'format': 'xquery' })
return map:for-each($data, function($k, $v) {
  $k || ': ' || string-join($v, ', ')
})

But my Object is more complex and I don't know, how to get two and more 
datasets with $k and $v out of the object. 
I want to have the following list:
<div>
<li>
        <ul>
        <li><span>Score: </span> <span>result score</span></li>
        <li><span>Blatt: </span> <span>result blatt</span></li>
        <li><span>Autor: </span> <span>result autor</span></li>
        <li><span>Titel: </span> <span>result titel</span></li>
        <li><span>Text: </span> <span>result text</span></li>
        <li><span>Link: </span> <span>result link</span></li>
        </ul>
</li>
        <ul>
        <li></li>
        </ul>
etc.
</div>

Thanks for any help
