 So, if you've been browsing the repository list on Next.Late, you might have seen a repository called CdavLibrary and wondered what the heck is that. So we'll talk what it is, why we need it, what it can do for us and what it can do for you as a developer as well, and how you can get involved in development. So, what is CdavLibrary? It's basically a JavaScript ClientLibrary for Cardf and Cardf, so you can easily integrate it into your app, you just have to point it to the dava endpoint of Next.Cloud and you can easily grab all the calendars and address books of the user. This library will also be the core of the Next.Generation contacts and calendar apps. Obviously, like everything we do at Next.Cloud, it's completely open source and free software, so it's HGPL licensed and our aim is that it's easy to use. So, as I said, you just hand over the path to the dava server to the constructor and you can easily access everything you need. It's not in single purpose but yet powerful, so it will help you to solve the issues you have with color and it will easily give you access to everything. Why we need it, yes, so at the moment, calendar and tasks are basically using their own color implementation. The Cardf library used by context is not that well maintained and also not extensible enough, so we thought, hey, Cardf and Cardf are pretty similar, why don't we join forces and build our common library that also provides Next.Cloud sharing and publishing capabilities. So what it can do right now already, it can do Cardf and Cardf, it will be able to do sharing and publishing very soon and what's coming up in the near future is kind of scheduling and availability so that you can easily access free busy data from within that library and we are also aiming for implementing collection synchronization so that you can easily get like the diffs and what's new on the server when you use that library. But it's also something it can do because we want to keep it single purpose. It can't do any parsing of iCalendar or vCard whatsoever, that's still your job as an app developer then. So yes, how to get involved if you are interested, John and me are going to meet up later upstairs if you are at the conference right now or you can just ping us in IRC either in Next.Cloud Calendar or Next.Cloud Contacts or you can simply open a ticket in the CEDAF library. Thank you. .
