Tag query

The query tag performs a query on a dataset and returns a Pandas DataFrame. Here are parameters of the query tag:

Name	Description
`dataset`	Name of a dataset to query (default `kb`)
`datastore`	Data backend. `duckdb` and `rdflib` are available for now. (by default, `rdflib`)
`isfilepath`	A bool value to denote if the given data is a file path or not (default `True`, which denotes the given data is a file path)

Example 1: the given string is not a file path

{% query "test", datastore="rdflib", isfilepath=False %}
    SELECT ?s ?p ?o
    WHERE {
        ?s ?p ?o
    }
    ORDER BY ?s ?p ?o
{% endquery %}

Example 2: the given string is a file path

{% query "test", datastore="rdflib", isfilepath=True %} query_file {% endquery %}

Here is the query_file's content:

SELECT ?s ?p ?o
WHERE {
    ?s ?p ?o
}
ORDER BY ?s ?p ?o
