This example demonstrates a SPARQL query against DBpedia, retrieving titles, publication dates, and page counts for books authored by David Foster Wallace. The query uses the `d:` and `dbpedia2:` namespace prefixes to access DBpedia ontology and property data, with results ordered by publication date. The code defines a `PREFIX` for the DBpedia ontology and a `SELECT` clause that binds three variables—`?title`, `?pubDate`, and `?pages`—from matching book resources. It relies on DBpedia’s SPARQL endpoint and standard RDF predicates like `rdfs:label` to fetch the displayed fields. The visualization itself is not shown in the snippet; only the query logic and data-fetching structure are provided.

SPARQL queries for the Semantic Web Working Group

This example shows three SPARQL queries that explore the Wikidata knowledge graph. One query counts paintings containing cats versus dogs to test a hypothesis about which animal appears more frequently. Another generates an ImageGrid view of Rembrandt’s artworks using the defaultView directive, while a third lists Spanish painters and sample images of their work. The queries use standard SPARQL syntax with property paths (wdt:P135/wdt:P279?), label service calls, and BIND for computed values. Results render directly in Wikidata’s query service interface.

Example SPARQL Query for DBPedia (Source: https://github.com/gklyne/asqc)

This example shows a SPARQL query that retrieves data about English musicians born in Exeter from DBPedia, returning their names, birth dates, and English-language descriptions. The query uses the DBPedia ontology and property vocabulary (such as `dbo:birthPlace` and `dbpedia:Exeter`) along with standard RDF and FOAF predicates. It filters descriptions by language using `FILTER (LANG(?description) = 'en')` to ensure English results. The query relies on the SPARQL endpoint’s built-in support for DBPedia’s RDF triples, with no additional visualization library involved.

DPLA Data

This example queries the Digital Public Library of America (DPLA) API to fetch and display search results as a simple webpage. It shows a list of image thumbnails with titles, each linked to its source item. The code uses the XQuery `fetch:text` or `fn:json-doc` functions to retrieve JSON data from the DPLA API, then parses it with `json:parse` or direct JSON navigation. It constructs HTML `<li>` elements containing an `<img>` tag and anchor, filtering out results without a thumbnail or title.

Loading data through SPARQL

This example demonstrates how to query a live SPARQL endpoint using d3.json, fetching up to 1000 records created in 1893 from the Dutch Network of Digital Heritage. The results are displayed as raw JSON text in a paragraph element. The code encodes a SPARQL query with encodeURIComponent and appends it to the endpoint URL, then parses the response with d3’s JSON loader. It relies on d3.v5 and the public API endpoint, which must remain active for the example to function.

Some books

This example visualizes a collection of 20 books from a CSV file, grouped by binding type into hardcover and paperback categories. It shows the distribution of books across these two formats, with each group’s count displayed as an attribute. The code uses XQuery 3.1 with `fetch:text` and `csv:parse` to load and parse the data from a Gist URL, then groups records by the `Binding` field and orders them alphabetically. The rendering approach is plain text output, with no graphical libraries, relying solely on XQuery’s element construction to list the grouped records.

Full Text IA

This example visualizes the full-text metadata of a book collection, showing how documents are distributed across subject categories. It loads book records from an XML database and filters out any documents tagged with the "Protected DAISY" subject. The visualization uses D3.js’s force-directed layout to position nodes, with each book represented as a point linked to its subject keywords. The code retrieves data via an XQuery query, and the rendering relies on D3’s force simulation to cluster related items, making thematic groupings visible at a glance.

Steve Baskauf's SPARQL query for ORCIDs at Vanderbilt

This visualization identifies people who are both students and employees at Vanderbilt by querying ORCID data with SPARQL, then displays their names and works as a network. It shows the overlapping creators between the two groups before revealing individual contributors. The code uses a SPARQL query with `MINUS` clauses to filter statuses and `ORDER BY` family name, running against a Vanderbilt ORCID graph. The rendering relies on standard SPARQL result processing, with no external visualization library specified; the output is a simple tabular or list-based view of the matched names and works.

Wikidata for Theological Librarians

This example demonstrates how theological librarians can use Wikidata to explore and visualize interconnected scholarly data. It shows a SPARQL query interface that retrieves information about theologians, their works, and associated religious concepts, rendered as an interactive network graph. The visualization uses D3.js’s force-directed layout to position nodes and links, with hover tooltips revealing entity details. Data is sourced live from Wikidata’s public endpoint, while the code employs the `d3.forceSimulation` API for physics-based layout and custom SVG rendering for clarity.
