Diego,For the competition to be of value, we MUST first describe the competition i.e. its fundamental goals etc..

Again, that isn't news to me :) If you would deploy it on http://dbpedia.org/resource/ and back it with DBPedia SPARQL endpoint, it would be a Linked Data server which also happens to have the same (X)HTML view. What else do you expect? Please understand my comments. Bottom line, you are not the only person working on Linked Open Data tools. There are many folks working on lots of tools in this space. If you feel strongly about your product, then why not make your case democratically? For instance, at OpenLink Software, we practice what we preach. We could have replaced the green pages in 2008, but we didn't feel that was democratic. Thus, we've simply been waiting for a better time to resurrect the need for alternatives to the default DBpedia Linked Data Pages. Again, an open competition would provide a variety of benefits to the community at large. We certainly need to have DBpedia's default HTML interface (which is a Linked Data Browser in HTML) updated. Fine, lets do a competition! Good! First step would be to describe what's expected of the default Linked Data page. Ideally, that can be constructed in an TURTLE document :) Kingsley On Fri, Feb 6, 2015 at 9:00 PM, Kingsley Idehen <kide...@openlinksw.com <mailto:kide...@openlinksw.com>> wrote: On 2/6/15 2:12 PM, Martynas Jusevičius wrote: Kingsley, with all due respect, what are you talking about? What visualization? Did you look at the example? Yes, of course I looked at the example. It's an HTML page. Just like the DBpedia green pages are HTML pages. HTML pages are ultimately visualization of data encoded using HTML (Hypertext Markup Language). It is a generic Linked Data browser interface, which also can be used to publish Linked Data datasets such as DBPedia. All it uses to render the page is the RDF result it retrieves from the source. It is a Document endowed with controls (courtesy of HTML). The controls in question enable a user lookup HTTP URIs that identity the subject, predicates, and objects of relations represented using RDF statements. That's it! As to "why?" -- because it is much more user-friendly? Is that not a goal for DBPedia? And as I said "user-friendly" has nothing to do with it. Even more so when you are making an utterly subjective qualification -- in a realm that'ssupposed to be underpinned by objectivity, courtesy of entity relationsemantics comprehension. Let me hear about non-obvious capabilities that are required, and see if we can meet them. We're offering to contribute open-source code. You are not the only one that would like to offer an alternative default to the pages that visualize the entity descriptions in DBpedia's Linked Open Data Space. Hence my suggestion of an open competition, which would actually do this project a world of good, ditto the Linked Open Data community in general. The community can vote on their preferred default visualization, how about that? Totally open and objective :) Kingsley Martynas On Fri, Feb 6, 2015 at 8:00 PM, Kingsley Idehen <kide...@openlinksw.com <mailto:kide...@openlinksw.com>> wrote: On 2/6/15 11:46 AM, Martynas Jusevičius wrote: Hey all, as some of you might know, our company has been developing Graphity - an open-source Linked Data client, which provides browser functionality and more. Here's an instance of it running on Linked Data Hub, rendering DBPedia resource of Tim Berners-Lee: http://linkeddatahub.com/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FTim_Berners-Lee You can compare it with the current interface: http://dbpedia.org/page/Tim_Berners-Lee I think it is safe to say that user-friendliness is on another level. Also check out the SPARQL endpoint which contains an interactive query editor. I would like the DBPedia community to consider making Graphity the default Linked Data interface. Why? You are adding a visualization to the mix. The tool in question is already listed on the applications collection[1] page currently maintained for the project. Please remember, Linked Open Data is all about loosely-coupling the following: 1. Object (Entity) Identity 2. Object (Entity) Description Location -- basically the Name->Address indirection that's crucial to any Identity based system 3. Notation used to construct Object (Entity) Descriptions 4. Wire-Protocol used to serialize Object (Entity) Descriptionsover a network 5. Data Access Tools for interrogating, manipulating, and visualizing Object (Entity) Descriptions. DBpedia publishes 5-Star Linked Open Data. You, like many others, have built a nice data visualization tool. Great job! But that isn't a mutually exclusive endeavor relative to DBpedia (the data space), it's a nice addition to the mix :) Do we need an upgrade of the default green pages? Of course! Getting that rolled out is something that's been looping for a while because the capabilities required are a little more challenging than is obvious. Maybe, at some point, we could have a competition for the community to vote on re., new default interface. The beauty of said competition is that outlining the expectations provides a nice route to actually discussing Linked Open Data visualization matters, clearly etc.. After that, we could take things much further: enable editing mode, add custom layout modes etc. Please let me know what you think.
