enapso-sparql-tools
Generic SPARQL query generator for Node.js
This package provides of the following features:
- Class Manager, ontology class cache to use OWL classes as a schema
- Prefix Manager, manages the prefixes for the named prefix notation of ontology IRIs
- Generator, SPARQL generator for class, property and annotation operations as well as CRUD-Operations for individuals
The concept is to:
- specify classes in a W3C-compliant ontology modelling tool
- import the model into a W3C-compliant semantic graph-database (e.g. Ontotext GraphDB)
- read the classes of the model into a Class Cache in a node.js application
- let the node.js application automatically generate the SPARQL queries for CRUD operations for the individuals of the specified classes (done by this library)
- Perform the generated SPARQL queries against the semantic graph-database to manage the individuals (supported by the enapso-graphdb-client package)
This package is SPARQL 1.1 compliant. It is designed to run on all SPARQL 1.1 compliant databases. The following demos use the Enapso GraphDB Client. Therefore, these examples require a running GraphDB 8.x/9.x instance on localhost at port 7200. The demos as well as the automated tests require a fully working Ontotext GraphDB repository "Test" and a user "Test" with the password "Test" being set up, which has read/write access to the "Test" Repository.

This project is actively developed and maintained. To discuss questions and suggestions with the Enapso and GraphDB community, we'll be happy to meet you in our forum at https://www.innotrade.com/forum/.
