The metadata is the surveillance data, and it's surprisingly intimate. Metadata speaks to our relationships, our associations, what we're interested in, what's important to us. It's really who we are.
All you have to do, the data doesn’t get altered when you enter it into an Excel Spreadsheet. It retains what one of my friend's calls its status as a data nugget where the metadata is attached to that from the tag and it retains its identity wherever it ends up being used. the next step is to provide tools. I was hoping that my friend Gordon Wattenberg would be here today because this is a tool that Martin developed before he joined Google when he was over at IBM called Many Eyes and its symbolic of a wide range
Hello, professors. It's great to see how far the course has come since the first semester in which I was a student. The metadata of your phone calls-- it doesn't reveal that much about you.
And also, data that isn't the content of communication, even if you're an American, if the data is not the content of communication, if it's only the metadata, that also doesn't have Fourth Amendment protection. So using creative lawyering, the Bush Administration helped to create an innovative series of mass surveillance
And the idea went this way. So metadata is wonderful.
We heard President Obama say that a year and change ago. And metadata is fundamentally surveillance data. To me the way to think of it is just do a thought experiment.
That's all the metadata. The metadata is the surveillance data, and it's surprisingly intimate. Metadata speaks to our relationships, our associations, what we're interested in, what's important to us.
access-controlled and we want to move it to another cloud? What metadata do we have to move to the other cloud and how will it be interpreted and will that access control continue to be observed? These are all questions that don't yet have answers or maybe, in some cases, too many different answers, because we have so many different options, you know, SOAP and UDDP and all -- UDDI and so on from the Web world,
He was also taking new perspectives on thing. Teaching others to metadata using an app, that's something very different. Chance was motivated by getting a lift from a friend.
Whereas the Airbnb thing is that, don't go there, live there, this knowledge of the expertise. And then the metadata clearly is-- it's like the same city. These are all the same landmarks.
programs that took advantage of this home field advantage. Bulk collection of metadata-- that means collecting all of it, analyzing it for patterns that would hopefully uncover terrorist groups. And then going after the content of communications where the target, the direct target is someone who's a foreign person outside the United
Usually they have some purpose for doing this other than looking at everybody's information, and they use people like me, lawyers, to try to enforce policy constraints on the analysts. What about all my metadata?
like that so you can see in this case a fly at the top there and then you can see that set of labels underneath it that's the metadata in many cases we're much more interested in that data than we are to be honest in the fly we'd like a leg off the fly get the genome from it then we want the data now you can see at the moment what we do is we tend to onep
But still, even there, they would have to imitate the voice of the entire session. Another thing is-- The metadata.
So in very simple form, it's really a collection of metadata about objects that are around the world that have been curated in various ways related to America. That's in this metadata repository. There's a mechanism for ingesting it.
And the idea went this way. could use the metadata to figure out which example you wanted to take.
And the idea went this way. The notion of metadata rather than content being shared.
And the idea went this way. The notion of metadata-- if you look at the library rules, they say you're not allowed to have more than, whatever the number is,
I get a report of where he went, who he spoke to, what he did. That's all the metadata. The metadata is the surveillance data, and it's surprisingly intimate.
We get our clothes ready the night before. So we're not going to metadata necessarily, but we are going to do this quick little breathing exercise.
And the way to interpret this data is that people first adopt particular attentional states, We will just look at metadata.
To illustrate how this has happened again throughout history, I want to go to 1851, my hometown, New York, It had really incomprehensible titles and metadata.
And the idea went this way. So when you talk about metadata, I couldn't agree more.
And it's much easier to store, to search and analyze. Take an obvious example of metadata is our location data produced by our cellphones. We carry them around all the time.
I talk about things I think governments should do, things I think corporations should do, which often are government corporations. They don't affect the metadata, and they rarely affect third-party data.
technology that allows us to capture all of these things, and that's important. But now we want to go beyond metadata. So what are the happenings that are going on, and what can we do to add a little bit more context to that?
OpenStudy is a very small group that started a couple years ago that is providing free student study groups online where students who maybe are using OpenCourseWare can ask There will be some interest group in metadata, for example.
make it available to other people through metadata that they might add to it and i think lastly this is sort of the
Hello, professors. It's great to see how far the course has come since the first semester in which I was a student. And I wanted to hear your thoughts on aggregated metadata and how concerning that is, but I think you've answered that.
different similarities and also match it relative to our other metadata.
The latest science shows-- and this is going over metadata analysis with lots of different people.
There's other forms of rallying around interest groups and other metadata that brings people out to the kinds of thematics that we explore.
But what happens if you match it with some metadata, like you match it with the names of the restaurants that I have attended?
Now combine it with some other types of metadata, like combine it with the history of geographical locations of other people.
Now, I say ended, but it's important to understand, they ended the bulk collection part of the program. The NSA analysts still were given access to this metadata but on a case by case basis. It turns out that that made the program more effective.
So as we have built the digital public library, it has come with a series of releases and ultimately been a technical project to start. Second, libraries are about metadata. They are about the data that describe where the data are.
And the idea went this way. I think the series of rules that constrain what counts as metadata is really a potentially destructive thing.
It's sort of if you could look at the metadata from all of these photos, it's a pretty revealing picture of how we live.
So my most recent company is just about extracting metadata from photos.
it's amazing the expressions you get. But if you're not doing that beyond metadata, beyond this is this point in time and here's what was going on, et
OpenStudy is a very small group that started a couple years ago that is providing free student study groups online where students who maybe are using OpenCourseWare can ask Are you developing some sort of standards for the metadata so people can find and put together parts of a program that makes sense for them across multiple institutions?
quando ele estala os dedos, metade do mundo desaparece.
The key part of that is we also want to alter the metadata.
So it's important that as The Obsidian uploads all of this metadata onto the internet when you type in black man, black woman, all this--
And secondly, if you think about what a library needs to have, it needs to have this huge store metadata. Libraries spend a huge amount of time and money creating often duplicative versions of metadata. And often they also worry about the intellectual property claims of this, that maybe there are copyright interests in the metadata.
And often they also worry about the intellectual property claims of this, that maybe there are copyright interests in the metadata. I would submit that there actually aren't good copyright claims for most forms of metadata. And in fact, if libraries were much more collaborative in terms of sharing their metadata, there would be many, many fewer forms of duplicative effort.
And the idea went this way. I think the fact that there's so much more in the form of metadata-- maybe I'm using a word that itself is too restrictive, so you might help me
for so long, and draw some of the metadata about TV shows and movies into the Kindle Fire tablet.
And in this flood of information, you also see a lot of metadata or customer data.
Hello, professors. It's great to see how far the course has come since the first semester in which I was a student. But, of course, we all know that metadata at scale is profoundly-- It's both profoundly useful if you're in the National security state.
