What is URIBurner?

A service from OpenLink Software, available at: http://uriburner.com, that enables anyone to generate structured descriptions -on the fly- for resources that are already published to HTTP based networks. These descriptions exist as hypermedia resource representations where links are used to identify:

  • the entity (data object or datum) being described,
  • each of its attributes, and
  • each of its attributes values (optionally).

The hypermedia resource representation outlined above is what is commonly known as an Entity-Attribute-Value (EAV) Graph. The use of generic HTTP scheme based Identifiers is what distinguishes this type of hypermedia resource from others.

Why is it Important?

The virtues (dual pronged serendipitous discovery) of publishing HTTP based Linked Data across public (World Wide Web) or private (Intranets and/or Extranets) is rapidly becoming clearer to everyone. That said, the nuance laced nature of Linked Data publishing presents significant challenges to most. Thus, for Linked Data to really blossom the process of publishing needs to be simplified i.e., "just click and go" (for human interaction) or REST-ful orchestration of HTTP CRUD (Create, Read, Update, Delete) operations between Client Applications and Linked Data Servers.

How Do I Use It?

In similar vane to the role played by FeedBurner with regards to Atom and RSS feed generation, during the early stages of the Blogosphere, it enables anyone to publish Linked Data bearing hypermedia resources on an HTTP network. Thus, its usage covers two profiles: Content Publisher and Content Consumer.

Content Publisher

The steps that follow cover all you need to do:

  • place a tag within your HTTP based hypermedia resource (e.g. within section for HTML )
  • use a URL via the @href attribute value to identify the location of the structured description of your resource, in this case it takes the form: http://linkeddata.uriburner.com/about/id/{scheme-or-protocol}/{your-hostname-or-authority}/{your-local-resource}
  • for human visibility you may consider adding associating a button (as you do with Atom and RSS) with the URL above.

That's it! The discoverability (SDQ) of your content has just multiplied significantly, its structured description is now part of the Linked Data Cloud with a reference back to your site (which is now a bona fide HTTP based Linked Data Space).


HTML+RDFa based representation of a structured resource description:

<link rel="describedby" title="Resource Description (HTML)"type="text/html" href="http://linkeddata.uriburner.com/about/id/http/example.org/xyz.html"/>

JSON based representation of a structured resource description:

<link rel="describedby" title="Resource Description (JSON)" type="application/json" href="http://linkeddata.uriburner.com/about/id/http/example.org/xyz.html"/>

N3 based representation of a structured resource description:

<link rel="describedby" title="Resource Description (N3)" type="text/n3" href="http://linkeddata.uriburner.com/about/id/http/example.org/xyz.html"/>

RDF/XML based representations of a structured resource description:

<link rel="describedby" title="Resource Description (RDF/XML)" type="application/rdf+xml" href="http://linkeddata.uriburner.com/about/id/http/example.org/xyz.html"/>

Content Consumer

As an end-user, obtaining a structured description of any resource published to an HTTP network boils down to the following steps:

  1. go to: http://uriburner.com
  2. drag the Page Metadata Bookmarklet link to your Browser's toolbar
  3. whenever you encounter a resource of interest (e.g. an HTML page) simply click on the Bookmarklet
  4. you will be presented with an HTML representation of a structured resource description (i.e., identifier of the entity being described, its attributes, and its attribute values will be clearly presented).


If you are a developer, you can simply perform an HTTP operation request (from your development environment of choice) using any of the URL patterns presented below:

  • curl -I -H "Accept: text/html" http://linkeddata.uriburner.com/about/id/{scheme}/{authority}/{local-path}


  • curl -I -H "Accept: application/json" http://linkeddata.uriburner.com/about/id/{scheme}/{authority}/{local-path}
  • curl http://linkeddata.uriburner.com/about/data/json/{scheme}/{authority}/{local-path}

Notation 3 (N3):

  • curl -I -H "Accept: text/n3" http://linkeddata.uriburner.com/about/id/{scheme}/{authority}/{local-path}
  • curl http://linkeddata.uriburner.com/about/data/n3/{scheme}/{authority}/{local-path}
  • curl -I -H "Accept: text/turtle" http://linkeddata.uriburner.com/about/id/{scheme}/{authority}/{local-path}
  • curl http://linkeddata.uriburner.com/about/data/ttl/{scheme}/{authority}/{local-path}


  • curl -I -H "Accept: application/rdf+xml" http://linkeddata.uriburner.com/about/id/{scheme}/{authority}/{local-path}
  • curl http://linkeddata.uriburner.com/about/data/xml/{scheme}/{authority}/{local-path}


URIBurner is a "deceptively simple" solution for cost-effective exploitation of HTTP based Linked Data meshes. It doesn't require any programming or customization en route to immediately realizing its virtues.

If you like what URIBurner offers, but prefer to leverage its capabilities within your domain -- such that resource description URLs reside in your domain, all you have to do is perform the following steps:

  1. download a copy of Virtuoso (for local desktop, workgroup, or data center installation) or
  2. instantiate Virtuoso via the Amazon EC2 Cloud
  3. enable the Sponger Middleware component via the RDF Mapper VAD package (which includes cartridges for over 30 different resources types)

When you install your own URIBurner instances, you also have the ability to perform customizations that increase resource description fidelity in line with your specific needs. All you need to do is develop a custom extractor cartridge and/or meta cartridge.
