There&#x27;s some more complex and curated projects out there, among them:<p><a href="https:&#x2F;&#x2F;www.wikidata.org&#x2F;wiki&#x2F;Wikidata:Main_Page" rel="nofollow">https:&#x2F;&#x2F;www.wikidata.org&#x2F;wiki&#x2F;Wikidata:Main_Page</a>

Signup page is blanking out for me.<p>Really curious to try it. It&#x27;s a really neat idea. Has this been done before? I&#x27;ve never seen anything like it.<p>The full value of this would likely come from interesting, productive, insightful visualizations of the underlying graph that is being built.<p>Questions that come to my mind:<p>- What if you write bots that scrape Wikipedia, Twitter, etc. and output entries from semantic analysis performed on these sources?<p>- If many people write such bots, how similar would the graphs be? What are the parameters that determine graph overlap?<p>- Can you use this to tie in to the real world?<p><i>&quot;A key can be any unique string such as product barcodes, book ISBNs, email addresses, URLs, domain names, names, phone numbers ...&quot;</i><p>Interesting stuff there... A way to make this into an interesting social network is if people curated their own graphs, e.g. of books and webpages and favorite restaurants, and other people could browse these graphs in a read only mode. (perhaps they can clone it to their graphs or so and then start to edit them)<p>The temporal aspect might be interesting too. Would there be value in seeing how my graph has changed over time? When I was in academia, none of the tools to keep track of the papers I read suited me. I could see this working well for this use case scenario.<p>(if you could write a Prolog against this, would it have interesting properties?)<p>I see that a submitter just posted 7630028603780 -&gt; volume -&gt; 75ml (the first number being probably the bar code of some beverage), that&#x27;s neat.<p>Someone else just posted the following entry:<p><i>5010438013621 -&gt; ingredients -&gt; Water, sugar, mixed fruit juices from concentrate 10% (Grape, blackcurrant, raspberry), acid (Citric acid), Vimto flavouring (Includes natural extracts of fruits, herbs, barley malt and spices), colouring food (Concentrate of carrot, hibiscus), acidity regulator (Sodium citrate), preservatives (Sodium benzoate, Potassium sorbate), Vitamin C, Sweeteners (Sucralose, Acesulfame K).</i><p>Now what the site should be doing is converting this to something like:<p><i>5010438013621 -&gt; ingredients -&gt; water<p>5010438013621 -&gt; ingredients -&gt; sugar<p>5010438013621 -&gt; ingredients -&gt; vitamin C<p>... </i><p>(Outpan person&#x2F;people, I&#x27;m in SF, if you want to chat more around coffee, there&#x27;s an email is in my profile)

does silicon valley now suddenly discover the semantic web and triplestores :O<p>if you want really all the data: <a href="http:&#x2F;&#x2F;lod-cloud.net&#x2F;" rel="nofollow">http:&#x2F;&#x2F;lod-cloud.net&#x2F;</a><p>but still, neat project.

As much as I like the idea, I can already see someone called &quot;Drumpf&quot; on the front page linking attributes about Hillary Clinton and Donald Trump to their Twitter accounts and not their names. I guess if you&#x27;re after &quot;everything&quot; then curation makes no sense but you&#x27;ll end up with a bunch of nonsense.

Great concept but I can see it falling out of line very quickly, on the homepage I spotted &quot;berlin -&gt; country -&gt; germany&quot; Followed by &quot;england -&gt; capital -&gt; London&quot;<p>If you search for the key &quot;germany&quot; it has no results, if you search &quot;london&quot; it finds no results.<p>The fluidity of the data is definitely a hindrance, if you wanted to use the dataset you&#x27;d have to already know what you are looking for to find the value.

Is 55 million keys a lot for tracking &quot;everything&quot;? My expectation was that &quot;everything&quot; would need more than 55 trillion keys.

So it&#x27;s RDF without the globally unique identifiers?

So searches like &quot;Linux&quot; &quot;California&quot; &quot;lincoln&quot; &quot;Hitler&quot; &quot;Disney&quot; and &quot;red&quot; return 0 results

What sort of backend storage does this use?

Is it possible to lookup all the attributes for a given value, say Trump?

Shame it fails for the trap of natural language ambiguity. So on the front page I see &quot;England -&gt; capital -&gt; London&quot; and at a glance I thought the capital (as in money) flows from England and is accumulated in London.
