SPARQL

SPARQL (Recursive acronym for SPARQL Protocol and RDF Query Language) is an rdf query language—that is, a semantic query language for databases—able to retrieve and manipulate data stored in RDF format.

It is utilized within the llm-wiki-cli render pipeline to populate tables based on inline graph queries.

Common prefixes

The LLM Wiki CLI automatically binds your namespace prefixes dynamically from the wiki.yaml file. The primary prefix mappings are:

• schema: https://schema.org/ (Standard schema vocabulary)
• wiki: https://wazootech.github.io/wiki/wiki/ (Your local vault namespace)
• rdf: http://www.w3.org/1999/02/22-rdf-syntax-ns# (Standard RDF attributes)

Example query types

Simple SELECT query

Extracts specific properties from your notes. For example, to list the names of all people:

PREFIX schema: <https://schema.org/>

SELECT ?person ?name WHERE {
  ?person rdf:type schema:Person .
  ?person schema:name ?name .
}

Filtered query

Uses standard string or URI filters to constrain your results. To list all articles in the wiki: namespace:

PREFIX schema: <https://schema.org/>

SELECT ?doc ?name WHERE {
  ?doc rdf:type schema:TechArticle .
  ?doc schema:name ?name .
  FILTER(STRSTARTS(STR(?doc), "wiki:"))
}

Active database summary

The table below queries the active graph to list all distinct classes currently instantiated in your vault:

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>

SELECT DISTINCT ?class WHERE {
  ?s rdf:type ?class .
  FILTER(STRSTARTS(STR(?class), "https://schema.org/"))
}
ORDER BY ?class
