 So, good afternoon all of you, I was, I joined during your introduction, when your introduction was going on. So, I know a bit of your background. I think most of the people are from second year who have completed their second year and are going to enroll in their third year and I will introduce myself. My name is Yogan Sharma, I am designated as software engineer, I am part of the project coordination team here under Professor Fartak and Professor Kannan Madgalyan. We work on several different projects. Some of you, you had just known about like the ESOS projects, like the OER project. We are also working on an interesting project, which is named National Virtual Library of India. So, I have a good news, I have two good news, would you like to hear? So, the news is that I have this only slide in my presentation. So, mostly I will speak and I will try to interact with you all. Secondly, it is only, I think, lesser than 15 minutes for the lunch break. So, you all must be excited about it. How many of you had a good breakfast today? Raise your hands. Okay, so, I can see the hunger in the atmosphere. Good. So, you have come from like all over India, different states, different colleges. How many of your colleges have a library? Raise your hands please. I think most of the institutes have a library. Now my question is that how many of you ever visited to your libraries? Okay, a fair bit. Good. Okay. So, the ones who visited, what was the process of like finding the books in the library? Or you knew that this was the book. I want this and you directly went into the catalog section or the book section and you got it. Was it the case or you just walked in and with the thought of exploring new books and went through the catalogs and saw the library? So, I know the answer. There would have been both the cases, right? How many of your libraries are automated and you get to access a kiosk or a computer desk wherein you can search the catalog of your entire library? Do you have? Very good. I would recommend you must visit the library over here in the IIT. It's a pretty huge library and it's a very good library. You will get to access a lot of good books here as well. So I can see that the library automation has happened in a majority of the libraries. Now imagine if you want to, if you want to access the catalog of any other library beyond your own institution, has anyone done that through any of the systems, websites, modules you have? Anyone? No, right? But supposing, just think of this idea that if I want to access the library of, say, NIT Rorkela, NIT Trichy, triple IT Jabalpur, how it is possible? So, we are trying to make it possible through a platform named National Virtual Library of India. And right now, we talked about only the academic libraries. How many of you ever visited to a public library? Which hosts thousands of books, lakhs of books beyond academics, okay? So I'll brief you about this project. This project is entrusted upon IIT Bombay by the Ministry of Culture. And to start with, we are bringing the data of all the libraries, public libraries under Ministry of Culture on one single platform. This will not only help the general audience, the general masses, readers, but it will also help the research scholars across streams. Not only the technical streams, but the non-technical streams as well. Now in order to execute this project, we have another partnering institute named IGNU. If you have heard, IGNU is an open university based in Delhi. We had a former partner, CEDAC. This portal, there has been different versions of this portal. Right now, the portal is undergoing some beta testing and the portal will be ready for public in the coming months. It will be released for the general public. Now, in order to bring the catalogs or the data of so many libraries, can you just estimate the number of libraries in India, academic and public in total? How many it would be? Just a guess, a random guess. Anyone? So the good thing is, even I don't know it. It's in thousands of course, but I don't have an authentic source of information somewhere I read that it is close to 50,000 plus. Now imagine the volume of data we will have to deal with for developing such a system. It's huge, it's in petabytes. So when we are developing such a system, we also have to plan how we will be hosting it. So as part of this project, what we did, we here in IIT set up the first ever cloud with 4 to 5 petabytes of storage. So we were involved in the process right from defining its requirement to the tendering process to the procurement, to the setup, testing, commissioning and I was just going through your activities or the projects that you will be working on and some of the projects, in some of the projects you will have to deal with the cloud infrastructure as well. So it will be good for you to know a bit about the cloud technologies and probably you will be also visiting the cloud itself where it is, the infrastructure where it is hosted. So this was another part of the project and it's a pretty interesting one, you know, managing huge volumes of data, making it searchable, making it easily searchable for the user. Another thing, another activity was that when I asked you that how many of your libraries have library automation, some computer-based software-based indexes, software-based catalogs, not all of you raised the hands. So there are still libraries, specifically public libraries, which have not gone through this migration. They still maintain the hard copy index registers, catalogs. So library training for those librarians to migrate and automate their libraries is another activity of this project. So I'm sure many of your colleges are remote centers and some way associated with IIT Bombay for different capacity building programs. Through these remote centers, we conduct a capacity building program called train 10,000 librarians at a time. So we remotely conduct sessions for the library staff as well as the technical staff in libraries and help them automate and migrate to softwares such as Koa and dSpace. These softwares, Koa and dSpace, I'm not going to take a class of these softwares, I'm just in very short explaining what do they do. A library has, you know, two types of data, one is the cataloging data wherein using which referring to which you can search what all is there in the library. So that data is mostly handled by the Koa software. There are of course many softwares in the world, but Koa is an open source software and it is most widely used and accepted. So Koa is used mostly for the bibliographic data and in a library whose content are also available in a digitized format, a digitized format, I mean, in the form of say images, PDFs, eBooks, ePub books. So that data is hosted on a software named dSpace and if you search on Google Open DOAR, you will find a directory of libraries across the world whose data is being hosted on different dSpace instances and it is open to access for public. Ignu, who is one of the partners in this project, they are helping us in this migrating effort and in setting up these Koa and dSpace instances. Another challenge I will talk about, one was that the huge volumes of data that we are talking in petabytes. Another one is making that data ready for the use in this portal. A lot of data, even in our personal systems when we, you know, organize our files and things, they are not very nicely organized. We rename the files like anything. So similar cases happens in the libraries as well. When we visited some of the libraries and we got the data and we realized that majority of the data was lacking some information. So a record in a library consists of two types of information. One is the metadata. Metadata talks about who the author is, what the book is, when it was published, etc., etc., where it is located and the other is the data itself, the file itself. So this metadata part, a lot of information was missing. So IGNU is helping us in curating that data. So the flow goes like this, that we go and visit a library, we collect the data, we help them migrate, we help them automate, then we curate it, then we harvest it. For that we have written a harvester program and so as part of this portal. And then finally it renders on to the portal in an easy to use manner. So this is in a nutshell about this project, it's a pretty interesting project. Beyond libraries, we have some other, we are bringing the data of some other cultural organizations as well and we plan to bring the data of other organizations like museums and a few other organizations. But it's still in progress and it will take a lot of time. So I hope you find, found it informative and pretty soon when it will be launched for public, I hope you'll use it. So this is one of the project that we are using and I'm open to questions if you have any. It can be related to the lunch or break also. So no questions. Anyways, I'll be meeting you again in one of my presentations tomorrow and wish you good luck. Thank you.
