# Data ## Overview This directory contains routes related to **user-owned data items** (UserData). It provides endpoints to retrieve or delete a specific UserData entry by its identifier, and includes deeper routes to execute actions attached to a given data item (notably SPARQL query execution). ## Modules ### 1. User data item (`{id}.js`) This module handles operations on a single UserData entry identified by `id`. It supports retrieving the full entry and deleting it. Delete operations enforce access control: a user can delete the entry only if they own it or if the entry is marked as writable; otherwise the API returns **403 Forbidden**. ### 2. User data execution (`{id}/exec.js`) This module executes the action associated with a UserData entry. It currently focuses on executing stored **SPARQL queries**: it loads the query from the UserData content, optionally applies templated parameters (e.g., `limit`, `offset`, and custom variables), enforces user-level query filtering, and returns the query result in the requested output format. ```{toctree} :maxdepth: 5 :caption: Contents {id}/index ``` ## Files in this directory - `{id}.js`
