    [ https://issues.apache.org/jira/browse/JENA-1435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16265266#comment-16265266 ] 

Andy Seaborne commented on JENA-1435:
-------------------------------------

At least initially, this extensibility is only supported for the programmatic Fuseki server and have a programmatic configuration API. (No classpath problems.)

> This ticket is to provide a mechanism so that application code can add custom operations.
> The built-in set includes the operations usually in {{/dataset/sparql}}, {{/dataset/update}} etc. as configured by {{fuseki:service*}}. These are also available as requests on the dataset directly as {{/dataset}}. For query, either parameter {{?query=}} or a content type {{application/sparql-query}}.
> Example extensions: 
> * An RDF Patch processor
> * Upload and convert non-RDF formats
> * Extract custom output formats
> * Filtering requests before passing onto the general operation
> This extension point would support:
> * dispatch by operation name
> * dispatch by Content-Type
> Dispatch by HTTP parameters will be designed for but not enabled.
> See also JENA-1400  (extensible operation names).
