----------------------------------
Summary: UI Interface for Jena Fuseki
Key: JENA-420
URL: https://issues.apache.org/jira/browse/JENA-420
Project: Apache Jena
Issue Type: New Feature
Components: Fuseki
Reporter: Stephen Allen
Fuseki could use an overhaul / rewrite of the web interface. It would be great
to design a nice web-based GUI interface for both querying/exploring the data
and for managing Fuseki itself.
Tools and skills that may be required:
Java, HTML+CSS, Javascript, Velocity (templates used server-side in place of
JSP)
A few ideas to get started:
1) Resource Explorer
This interface allows the user to select any resource from either a list of all
triples in a graph, or from the results of a SPARQL query. After selecting the
resource, they can view all of the statements that reference the resource.
2) Improved Query Input
It would be great to enhance the query input form for both queries and updates.
Some features here that could be useful would be an IDE-like input box that
performed syntax highlighting, automatic indentation, and easy commenting out
of selected lines of text. Additionally being able to pre-populate the input
box with the user's commonly used prefixes would be great (stored in a cookie
or some such).
3) Improved Query Results
Better display of query results (especially SELECT queries). Already mentioned
was a tie-in to the Resource Explorer, so a user can easily see the statements
about some interesting resource in the results. But it would also be great to
layout and format the result table better. Even display the results on the
same page as the query input box using AJAX. Or allow the table to be resorted
after the query results have been returned. Also display the total number of
rows.
4) Query Management
View and manage currently running queries. Display how long queries have been
executing, and allow the user to cancel queries that may be taking too long.
5) Fuseki Management
There are many tasks here that would be great. Expose JVM properties via JMX
in a nice UI. Things like CPU/Memory usage, disk space remaining, etc. Allow
initiation of back-up tasks. Allow the user to download a snapshot of the
repository. Shut down the server. Possibly add and remove datasets
dynamically.
