Modules

Jassa-Core

This library is a swiss army knife for dealing with SPARQL queries and result sets from JavaScript. It is comprised of a set of layered modules, ranging from a (low-level) RDF API over a service abstraction layer, a SPARQL-JSON mapping layer up to a faceted browsing layer. Jassa lets you focus on application development rather than getting tangled up in SPARQL details. Note, that Jassa-Core can be used in both server- and client-side scenarios.

Jassa-UI-Angular

This module provides Angular components for working with data in SPARQL endpoints built on top of the JAvaScript Suite for Sparql Access (Jassa).

• Jassa-UI-Angular-Core
  • Provides widgets for faceted search
• Jassa-UI-Angular-Edit
  • A toolkit for making RDF editing with HTML forms easy by introducing a set of attributes.
• Jassa-UI-Angular-OpenLayers
  • A widget for connecting an Openlayers map on the fly with a SPARQL endpoint. Works with large date through use of a quad tree space partitioning approach when querying for data.
