a1341 00:00:36.223 00:00:44.701 So going back to 1989, I wrote a memo suggesting global hypertext system.
a1342 00:01:15.334 00:01:18.001 I wrote the code, and put it out there.
a1343 00:01:18.001 00:01:21.221 Why did I do it? Well, it was basically frustration.
a1344 00:01:51.096 00:01:57.707 I would find the data may be, the information I wanted, in some new data format and they were all incompatible.
a1345 00:01:57.707 00:02:01.912 It was just very frustrating, the frustration was on all this unlocked potential.
a1346 00:02:04.689 00:02:16.990 So, if you just imagine they all being part of some big virtual documentation system in the sky, say, on the internet, then life would be so much easier.
a1347 00:03:08.953 00:03:13.056 That is the leap that was very difficult for people to make. Well, some people did.
a1348 00:03:13.056 00:03:16.718 So yes, it was difficult to explain, but it was a grassroots movement.
a1349 00:03:34.029 00:03:40.000 I asked everybody more or less to put their documents, say "Could you put your documents on this Web thing."
a1350 00:03:40.000 00:03:43.412 And you did, thanks.
a1351 00:03:56.844 00:04:00.018 Now, I want you to put your data on the Web.
a1352 00:04:18.469 00:04:20.976 Data, you can do all kinds of stuffs with the computer.
a1353 00:05:57.232 00:06:04.821 I want to think of about a world where everybody has put data on the Web, and so virtually anything you could imagine is on the Web, and I'm calling that Linked Data.
a1354 00:06:07.777 00:06:10.544 If you want to put something on the Web, there are three rules.
a1355 00:06:10.544 00:06:22.154 First thing is, that those HTTP names, those things that start with "http:", we're using them not just for documents, now we're using them for things that the documents are about.
a1356 00:06:32.503 00:06:44.581 Second rule: if I take one of these "http" names and I look it up, I go and do the Web thing with it, I fetch the data using the HTTP protocol from the Web, I will get back some data in a standard format.
a1357 00:06:58.185 00:07:06.838 Third rule is that when I get back this information, it's not just got somebody's height and weight and when they were born, it's got relationships.
a1358 00:07:06.838 00:07:10.482 Data is relationships. Interestingly, data is relationships.
a1359 00:07:48.655 00:07:57.036 The idea of Linked Data is that we get lots an lots and lots of these boxes that Hans had, and we get lots and lots and lots of things sprouting.
a1360 00:08:21.980 00:08:27.114 Chris Bizer at the Freie Universit├Ąt in Berlin was one of the first people to put interesting things up.
a1361 00:08:40.545 00:08:49.365 So he wrote a program to take the data, extract it from Wikipedia and put it into a blob of linked data on the Web; which he called dbpedia.
a1362 00:09:08.497 00:09:10.722 This is just a grassroots stuff again, OK?
a1363 00:09:13.496 00:09:16.814 Data comes in fact in lots and lots of different forms.
a1364 00:09:38.811 00:09:47.205 I'm just going to mention a few of them, so that you get the idea of the diversity of it, so that you also see how much unlocked potential.
a1365 00:09:47.705 00:09:48.292 Government data.
a1366 00:10:07.132 00:10:14.750 This is the data from all the government departments. Think about how much of that data is about how life is lived in America. It's actually useful, it's got value.
a1367 00:10:56.050 00:11:01.080 We have to ask for raw data now, and I'm gonna ask you to practice that, OK?
a1368 00:11:10.979 00:11:20.283 Practice that, it's important, because you have no idea the number of excuses people come up with to hang on to their data, and not give it to you, even though you've paid for it.
a1369 00:12:05.925 00:12:16.331 if you're looking at Alzheimer's for example, drug discovery, there is an whole lot of linked data which is just coming out because scientists in that field realize this is a great way of getting out of those silos.
a1370 00:13:25.018 00:13:27.727 In fact data is about our lives.
a1371 00:13:39.772 00:13:46.686 Data data data. Everytime you do things in a social networking site, the social networking site is taking data and using it, repurposing it.
a1372 00:14:10.600 00:14:16.509 One last type of data I will talk about, may be it's the most exciting, before I came down here I looked up on the OpenStreetMap.
a1373 00:14:16.509 00:14:18.430 OpenStreetMap is a map, but it's also a wiki.
a1374 00:14:43.406 00:14:51.149 The StreetMap is all about everybody doing their bit, and this creates an incredible resource because everybody else does theirs.
a1375 00:14:51.249 00:14:54.005 And that is what Linked Data is all about.
a1376 00:14:54.005 00:15:00.983 It's about people doing their bit to produce a little bit, and it all connecting.
a1377 00:15:31.972 00:15:39.836 It's about connecting it together, and when you connect data together, you get power in a way that doesn't happen just with the Web, with documents.
a1378 00:15:39.836 00:15:44.271 You get this really huge power out of it.
a1379 00:16:06.094 00:16:08.175 OK? So it's called Linked Data.
a1380 00:16:08.175 00:16:09.574 I want you to make it.
a1381 00:16:09.574 00:16:11.531 I want you to demand it.
a1382 00:16:14.122 00:16:22.993 Thanks.
