SPARQL support is an SPARQL client / SPARQL query editor works on web browser.
Auto-Completion : "Ctrl+Space" or "Tab", Submit : "Ctrl+Enter"

Set endpoint

## endpoint                                                   * 1st line only

Or sparql-doc format (refer to the following 'Beta' section)


Complement indents, variable names and prefixes with the "Ctrl+Space" or "Tab" key.

?h|             -->   ?hoge|
r|              -->   rdf:|                                                       * lower case
F|              -->   FILTER (|)                                                  * upper case
PREFIX obo:|    -->   PREFIX obo: <>|              * 1
<id>|           -->   <>|                                  * 2

*1 Prefix URIs will be taken from
*2 Private abridgement of URIs. Default has only this example. User is able to add in the comment line.(format : # id:<>)

Copy code and prefixes in other query.

e.g.) copy the 2nd query prefixes
PREFIX #2|    -->   PREFIX rdf: <>     * 3
                    PREFIX rdfs: <>
                    PREFIX dct: <>
e.g.) copy the 1st query
COPY #1|      -->   omit

*3 run in the 1st line of textarea.

Other completion

##|  ->   ## endpoint|                                 * 1st line only (recently used endpoints)
Def|  ->   DEFINE sql:select-option "order"|                                       * (for Virtuoso)

Tabbed Interface

Available multiple queries management by the '+' and the '-' button in the upper right corner. Queries are retained when the browser is restarted.
"Ctrl+Shift" : move to neighbor tab ("Ctrl+Alt+Shift", "Ctrl+[1-9]")
"Ctrl+[+/-]" : add/remove tab(w/o Shift)


Change the mode to click the 'i' button in the upper right corner.
Output results in new element in the current window.
Complement variable names start with '$'.(by the tab key)

$p|             -->   rdf:type
                -->   rdfs:subClassOf
                -->   piero:inRpairInSideA
                -->   piero:inRpairInSideB


Submit with "Ctrl+Enter"

- SPANG like shortcut.

# spang -S tax:9606 -L 100;|    -->   # spang -S tax:9606 -L 100;                 *4, 5
                                      SELECT *
                                      WHERE {
				        tax:9606 ?p ?o .
		                      LIMIT 100|

*4 supported options: -S (subject), -P (predicate), -O (object), -L (limit), -N (count), -G (graph list), -F (from a graph)
*5 rewrite under the command line.

- Font

# font-size: 20px;
# font-family: Courier;

- Clear all queries

# clear_sparql_queries;                                 * 1st line only

- Proxy SSL mixed content (permanent)

# mixed-content-proxy: true;                            * true (default), false

Access to endpoints which are not https via '' server from SPARQL support on https.


Multi-line comments for debug
- skip through from '=begin' to '=end' (available '=b' and '=e', support in the innerMode only)

=b multi-line
   comments =e

sparql-doc format

# @title example
# @endpoint
# @param city=Tokyo
# @param hoge=fuga

PREFIX dbpedia: <>
PREFIX dbo: <>
  dbpedia:{{city}} ?p ?o .

Proxy SSL mixed content and CORS blocking (temporary)
- via ''. sparql-doc format in comment.

# @temp-proxy true

Predicate search
- show predicates and sample of objects: "?subject ??" (reverse search: "?subject ^??", support in the innerMode only)

## endpoint
PREFIX dbpedia: <>
PREFIX dbo: <>
  dbpedia:Tokyo dbo:isPartOf ?parent .
  ?parent ??

----- results bindings -----

dbo:utcOffset	"+9"
dbo:timeZone	dbpedia:Japan_Standard_Time
dbo:length	1.3e+06
rdfs:label	"Honshu"

How to Use


Abailable in SPARQL support.


Available in the textarea of any site such as virtuoso web interface, by using UserScript manager.

Set target URLs in "// @include" line
(or DL modified js)

require: userscript manager (web browser extension)


Available in user own site by embedding code.

require: CodeMirror

SPARQList support is a markdown editor for SPARQList. (SPARQList is a REST API server which executes a SPARQL query, transform the result into formatted data.)
SPARQList support provides the execution environment of SPARQL and JavaScript in a step-by-step.

Drop-down list of SPARQLet contents being edited.
    • new SPARQLet
Create a new SPARQLet content.
    • remove SPARQLet
Remove showing SPARQLet content.
    • read markdown
Read a SPARQLet markdown format used in SPARQList server. (Available SPARQLet URL (req. CORS headers in the SPARQList server))
    • add step
Add a step (such as Parameters, SPARQL, JavaScript) to the SPARQLet.
Drop-down list of the environment modes of the step. (Handlebars: output only)
Rename a sparqlet step
    • copy markdown
Copy the markdown of the showing SPARQLet to the clipboard.

Recommended browsers: Google Chrome (v67+), Firefox (v61+), Safari (v11+), Microsoft Edge(v42+)

Endpoint browser is a web service to search RDF data in the endpoint using visualised network graph. User can select nodes and execute SPARQL queries from the GUI.

Start browsing

endpoint: URL of the target endpoint
entry: URI of start node (or literal)


browsing: browse RDF data in the endpoint by click nodes
subgraph to SPARQL: construct SPARQL query from the network graph
remove node: remove graph nodes
