enapso Apacje Jena Fuseki Administration Toolbox for Node.js
Admin client for Apacje Jena Fusekito easily perform administrative against your RDF stores, your OWL ontologies or knowledge graphs in nodes.js applications. This client supports an easy import of existing RDF stores and ontologies to fuseki by upload via file, the creation and listing of new dataset.
Get the latest version of Apache jena Fuseki for free at https://jena.apache.org/download/index.cgi.
After successfully downloading the zip folder of apache jena fuseki unzip the downloaded folder. To run the server of apache jena fuski and it work correctly you need to configure the shiro.ini file available in folder Apache_Jena_Fuseki=> run=> shiro.ini. Open the file comment the 26 line where it restricted to localhost /$/** = localhostFilter just need to add # in start of this line and save the file.
Now to run the apache server, you need to go to apache folder and run the batch file of apache-server.bat you will see a command prompt open and your server will be start on localhost:3030 port.
The following demo for fuseki require a running fuseki instance on localhost at port 3030 for which you need to a create a dataset name Test on fuseki server for which you need to go localhost:3030 click on manage datasets=>add new dataset
This project is actively developed and maintained. To discuss questions and suggestions with the enapso and fuseki community, we'll be happy to meet you in our forum at https://www.innotrade.com/forum/.

];Create an endpoint client with fuseki to perform operation:
let graphDBEndpoint = new EnapsoGraphDBClient.Endpoint({
baseURL: FUSEKI_BASE_URL,
repository: FUSEKI_DATASET,
prefixes: DEFAULT_PREFIXES,
queryPath: FUSEKI_QUERY_PATH,
updatePath: FUSEKI_UPDATE_PATH
});Create a new dataset in your Fuseki for which we need to pass the type of dataset and name of dataset.
graphDBEndpoint
.createDataSet({
name: 'AutomatedTest',
type: 'tdb'
})
.then((result) => {
console.log(result);
})
.catch((err) => {
console.log(err);
});Create DataSet:{
"success": true,
"statusCode": 200,
"statusMessage": "OK"
}Delete a dataset in the connected fuseki instance:
graphDBEndpoint
.deleteDataSet({ name: 'AutomatedTest' })
.then((result) => {
console.log(result);
})
.catch((err) => {
console.log(err);
});Delete DataSet:{
"success": true,
"statusCode": 200,
"statusMessage": "OK"
}
Get details of all datasets of the fuseki:
graphDBEndpoint
.getAllDataSet()
.then((result) => {
console.log(result);
})
.catch((err) => {
console.log(err);

}Get a specific dataset detail by passing its name:

.then((result) => {

}Upload an ontology to Fuseki dataset and optional context (graph) automatically if upload was successful:
uploadOntology
.uploadFromFile({
fileName: '../ontologies/EnapsoOntologyRepository.owl',
graph: 'http://ont.enapso.com/repo'
})
.then((result) => {
console.log(result);
})
.catch((err) => {
console.log(err);
});pass a graph name and the fileName in which path and name of file given and it will export the given graph from dataset
graphDBEndpoint
.downloadOntology({
graph: 'http://ont.enapso.com/repo',
fileName: '../ontologies/test.owl'
})
.then((result) => {
console.log(result);
})
.catch((err) => {
console.log(err);
});Caution! This removes ALL triples of the given dataset! This operation cannot be undone! The entire dataset will be emptied, i.e. all data of this data will be removed. The dataset remains active.
graphDBEndpoint
.clearDataSet()
.then((result) => {
console.log(result);
})
.catch((err) => {
console.log(err);
});{
"success": true,
"statusCode": 200,
"message": "OK"
}Caution! This removes ALL triples of the given context! This operation cannot be undone! The entire context will be emptied, i.e. all data from this context will be removed. The datset and other contexts remain active.
graphDBEndpoint
.clearSpecificGraph({
