Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

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. Get the latest version of GraphDB for free at https://www.ontotext.com/products/graphdb/.

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/.
