Overview
Stardog Studio is the IDE for the Knowledge Graph Engineer designed to make Stardog functionality easier to use for everyday users.
Aside from administering Stardog clusters, almost all functionality that exists through the CLI and other endpoints is available in Studio, and most non-admin users are able to interact with Stardog using Studio and without going to the command line.
To authenticate using Kerberos, both the Stardog server and your browser must be correctly configured. Check out the detailed documentation on how.
Studio’s UI is split into the sections below.
This is not a comprehensive list of functionality but a general summary of functionality in each section.
Provenance:
- Get a high-level overview of your knowledge graph
- Visualize connections between data sources (including virtualized sources) and entities in your data
Workspace:
- Write, execute, and see query plans for queries in SPARQL and GraphQL.
- Interact with constraints and rules in SHACL and Stardog Rules Syntax
- Edit RDF with TriG and Turtle
- Edit Virtual Graph mappings with Stardog Mapping Syntax
- See query plans
- Visualize query results as nodes and edges
- Create and edit Stored Queries
Models:
- Visualize your schema
- Create and edit OWL and RDFS defined schemas in a form-based experience
- Write, edit, and validate constraints
Virtual Graphs:
- Create and configure virtual graphs and virtual graph mappings
Data:
- Create and configure data sources
Databases:
- Manage databases
- Update database properties and namespaces
- See and kill running queries
- Load and remove data
- Visualize the schema
Security:
- Create users and roles
- Assign permissions to users and roles
If your Stardog server users and roles are managed through LDAP, Stardog Studio will restrict the creation of users and assigning of roles. From the Security hub, admins will only have the ability to manage permissions for users and roles.

Preference | Description | Default Value | Additional notes |
---|---|---|---|
defaultQueryPlanFormat | The default display format for the results of a query plan. | “visual” | Accepted values: “json”, “text”, “visual”. |
editorFontSize | Font size of all editor inputs. | 14 | |
editorToolTips | If true (the default), Studio will provide tooltips for definitions and errors in text editors. If false , Studio will not show any tooltips in any editor. | true | |
includeConstraintsInModelsHub | If true (the default), Studio will dynamically query for and write constraints from your database to a named graph for Constraints when creating and editing models in the Models hub. If false , Studio will not include that information. In rare cases, setting this to false can improve Studio performance. | true | |
labelPredicatesByDatabase | Label predicates order for search and visualization. These must be the full URI. | ||
modelsBaseIriByDatabase | Base IRI for creating new items in the Models Hub. This must be the full IRI. | ||
queryLimit | The LIMIT to apply (specifying maximum number of results) to all non-CONSTRUCT/DESCRIBE SPARQL queries run inside of Studio. | 1000 | If set to 0, this preference will be ignored. The maximum limit is 50000. |
theme | Studio color theme. If dark (the default), Studio will be displayed in a dark theme. If light , Studio will be displayed in a light theme. | “dark” | |
useSchemaForAutocompletion | If true (the default), Studio will dynamically include schema information from your databases, such as types and relationships, in autocomplete suggestions. If false , Studio will not include that information. In rare cases, setting this to false can improve Studio performance. | true | |
useSchemaForNamedGraphs | If true (the default), Studio will include named graph information from your databases in the named graph selector. If false , Studio will not include that information. In rare cases, setting this to false can improve Studio performance. | true |

Contributing
Stardog.js
Stardog.js is a Javascript library for communicating with a Stardog server. This is what Studio uses to interact with Stardog and it can be easily plugged into your own Stardog-based application.
Parsers
The parsers used by Stardog Studio are available on Github which provides support for all of the languages supported by Studio, from the standards like SPARQL and Turtle, to Stardog specific syntaxes like SMS.
Language extensions
In case you’d like to have Stardog Studio’s language intelligence available in other IDEs, we’ve made Studio’s language servers freely available as Visual Studio Code Extensions and as unpackaged JavaScript modules.
Collecting usage data
To improve Stardog Studio, we collect anonymous usage data. We only collect information like session duration, feature usage, and the size of queries and results. We never collect the actual content of queries or results. To opt-out, set telemetryConsent
to false
in your Preferences. You can access your preferences using the following keyboard shortcuts:
- Mac:
cmd ,
- Windows/Linux:
