 Yes, sir nice teacher pretty cool. Are you alone, or do you have some friends? Excellent and that will be one minute and 43 seconds over but we'll let you do it anyway They would Weinberger from the Harvard Innovation Lab And another of those with which I have a potential conflict of interest because they're great friends and neighbors as well over to you guys It's a thrill for our entire team to be here. I'll say it. This is an historic occasion It's a lot to the Digital Public Library of America. So it's really amazing to be here to be in the presence of these other Sprinters is my head and heart are exploding with the desire to interoperate thrilling so shelf life collaborative is proposing Two projects integrated one is library cloud, which does the heavy lifting the server underneath it and shelf life Which is it's far more gregarious application that runs on top of it. So library cloud is a metadata server. It gathers metadata from institutions libraries collections And makes it available through open APIs and as linked open data The aim of library cloud is to take everything that libraries know and make it all available to the entire web Ecosystem including other sites and services like Wikipedia that can take it up But also to developers and innovators who build perhaps recommendation engines or library analytics or other portals like like shelf life or who knows what that's the whole point So library cloud currently has about 15 million items in it Which means metadata about items. We don't collect content itself including Circulation data anonymized from the partner libraries which include three public libraries and two university libraries We also have been gathering metadata about web objects And we think of library cloud as a metadata amplifier that takes metadata adds value to it puts it out into the world Applications take it up feed it back in and every turn that metadata gets more value It gets amplified in its value Which means that the impact and value of the DP LA is also amplified So let's take a look at shelf life. This by the way is a screencast that we did not our hotel over Wi-Fi last night But it's real stuff. You can come see it in our booth or of course go to our sprint project online and Spend as much time as you want poking at it So our idea is that you would get to this site either by coming to DP LA org perhaps Or maybe you go to your local library site where an embedded DP LA shelf life widget gives Users at the local site access to the content of DP LA and also to many of its services So it's a doorway to DP LA or other apps perhaps that we interoperate with We got this is a page you see when you click on something you're interested in in this case We got here because shelf life recommended the Pluto files Because it knows about what we've been doing and at library cloud has a great deal of information about the general ecology of interest So the first thing to notice about shelf life is that it is a place We think it should be a place because we firmly believe that the DP LA is going to be a major web destination But it's also a place because Shelf life is not just a place that you go to look up something You know you want or to find something that you didn't know you want which is wonderful when that happens It's also a place to spend some time to explore the browse to navigate to Contribute to enhance to learn and to share with other people because it's social all the way through So this means it has to be accessible to everyone in fact the DP LA has to be accessible to everyone So we use the single most Common understandable simple user interface around which are shelves if you prefer The now's standard opac cover browser. We can do that too when we have covers. There are a bunch of them there So if the object that you're looking at is a book the width of the book indicates its page count Actually, its length is represents its actual length But if it's online then shelf life is a fully click-and-play Application so you click in this case we're going out to the open library In fact, we're using their embedded browser. So thank you open library for everything that you do. You're you're amazing If it's another type of media if it's a video same deal You click on it click-and-play and you can watch it the same for Audio and the same for web pages. We have 60,000 Wikipedia pages about books for example that you can click on so That's a lot of context, right These shelves are in fact special they're special in three ways and the first way is that this is our attempt to integrate Five the five collections that we have all on one infinite bookshelf now You can facet these back into their original collections because browsing by collection is a particularly useful thing to do But with shelf life you can also facet them so that you see all and only the content of your local library We think this is a pretty interesting way of combining the interests of the DP LA and local libraries Second way this is special is that the depth of the color blue indicates Community relevance or what we call shelf rank which we calculate based upon user interactions with it plus using that anonymized Data circulation data that we're getting from our contributors and the third way that this is special the shelf is that all Items occur all works of culture occur in a context in fact they incur occur in multiple contexts because human brain is very contextual That's what we do and so we allow you to pivot on say the Pluto files to see it in multiple contexts So one of the contexts is that which is carefully prepared by professional librarians as they categorize so you can click on one Of the categories or any of them and see this work with all of the other items Categorized in it by professional librarians, but we also want to combine that wisdom of libraries with the wisdom of users as well So you can see it in the context of what other users attend or how they Recommended works to bring them out of a long tail. You can also Create users can create collections and our collections are very simple dead easy to do You just select some objects you say make a collection you add it to an existing one You create a new one very very simple straightforward and powerful and useful we think but if you notice down here It says Chicago starry nights. That is in fact an extra murals collection is created by them And when you click on it, we'll take you to extra murals launch it and then you can use their beautiful beautiful browser So we provide a lot of context with shelf life. That's what it's about But the context for works is not just other works the context is people as well and so shelf shelf life is social all the way through social social social So you can for example, you can rate it you can Drop in some stars. You can like it. You can follow it and following establishes a longer-term relationship with the object so that you get notified when for example, there are new reviews or the author has published a new work or Discussion you are in has been added to or maybe Neil deGrasse Tyson is going to show up at your local library and do a book chat So these are all ways in which we have emphasized the social we think that's hugely important There's one more way here though you look these balloons on the right indicate that there's been some social activity around the object You click we drop you in immediately in place where you can comment read Start up a new topic and we've been thinking this is a possibility that perhaps Comments from librarians ought to be highlighted because we want to make sure that we gather as much of what libraries know and as much as Users crowds communities know as well and make it all available So There's much much more. This is just a little taste We encourage you to come to our booth or go online to see the whole thing But we hope that it gives you a sense of where we're going with this this Shelf life library cloud are real they work they scale But this is just the beginning of figuring out what this vision is and that's figuring out that vision It's something that we have to do together and we would love to do together with sprint partners with everybody here but the real opportunity we think for the DP LA is Not simply to connect people to work. So that's hugely that's revolutionary That's amazing. That will change the world But culture doesn't consist of people interacting with works the real opportunity we think for the DP LA is to connect people to people Through works because that's how you create culture. That's how it is created. That's how it Grows that's how it's enhanced. That's how it enters our lives That's how culture comes to matter to us and we think that is fully within the mission and the hope that we've heard today Of the digital public library of America, thank you So our team is is joining us as they come down. Yes a question up here Okay, great. Hi, my name is Laura Parsons and my question is Obviously, you're gonna gather a lot of user data using this. I'm wondering what your plans would be for that Which aspect of plans what we're gonna do with it a privacy issues Yes, both of those things There are plenty of things to do with it You can we have all seen examples know of examples of sites on the web that do amazing things with Knowing what users are doing opt-in opt-in. Let me say that again opt-in From library thing even Amazon does amazing things with it as well But you know, there's lots of reader sites that do things as well Obviously Amazon is not an opt-in example In terms of the policy that we think is determined by the DP LA we tend towards Opting in we default to protecting user privacy any of the circulation data that what we take into library cloud For example is entirely anonymized no identifiers date stamp is only to a day The IDs are entirely randomized so But the policy is up to the PLA Good hard questions buried there David other questions Because library thing knows a huge Library thing which we love and who is one of our partners first of all buying is interesting proposition But leave that aside library thing which we love many of us are users here I'm sure knows a huge amount what use about what users know what their preferences are what they're saying how in fact We're getting social we have social metadata from from them already. So for example in library cloud We know how many times a work is mentioned in the library cloud discussion not who just how many times that's really interesting Library cloud for all of its wonderfulness doesn't know what libraries know it knows what readers know and it's fabulous at that but we want to make sure that none of the Wisdom or the metadata of libraries is left behind It's great Zach Great work. It's incredible. It's amazing. What very well done. Okay. Thank you I love it. I mean I'm working on something similar and I had one suggestion for you Which is consider integrating social ranking with everything? I know you have a recommendation With stars and things like that But for comments and I like your idea of giving special emphasis to librarians comments and you could do something where you You allow readers to Rank up The best comments so that you're only exposed to you know the highest quality things I mean one of the problems that the internet is so chaotic and almost too democratic and so DPLA this effort we need to figure out a way to balance democracy with a kind of curation which librarians are best at It's a wonderful question a huge set of possibilities This is a problem that's been addressed by lots of different sorts of thinking and the key thing I think is to remember that Maybe remembers the wrong word cuz they didn't say this is an open system and especially with library cloud If you want a for example a different Recommendation engine you don't like the way you like you have different preferences Wonderful that is the best thing ever Fabulous well you guys are wonderful and thank you. I know this was a huge team effort as all of them were so Please join me in thanking the whole team
