B) Cloud of Cards Processing Library

motivations_usages_problems_01_02


Project developed by Christian Babski (fabric | ch)


Cloud of Cards Processing Library consists in the unification of three different API dedicated to online files and folders manipulation and the development of an additional fourth one specific to the needs of the Cloud of Cards kit and the Inhabiting and Interfacing the Cloud(s) research project. The overall final package has been adapted to the Processing development language and linked to the open-source cloud software ownCloud.

Additional behaviors are included that can also be used in relation to ownCloud (or Nextcloud), for both its server and clients. These additional functions are the implemented results of the design research process, linked to an ethnographic study about the cloud user experience.

Through the use of this new library written in Processing and linked to other open-source tools, it is now easier for a wider public to experiment, sketch and develop alternative interfaces, visual or physical applications for the cloud. In particular, the communities of designers and makers that are used to the Processing language.

I&IC’s OwnCloud Core Processing Library (evolution)

Note: “I&IC OwnCloud Core Processing Library” (working title) is part of a home cloud kit, which was described in a previous post and that will be composed by four various artifacts, both physical and digital.

The kit will be distributed freely at the end of the project.

One processing project with one cloud, while the server (OwnCloud) can still be accessed by a regular interface (OwnCloud client). The upper part (white) is the “network/server side” of the project (OwnCloud), hosted on a Linux server, while the bottom (grey dots) is user or “client side”. It can consists in connected objects or environments, interfaces, visualizations of different sorts.

 

The I&IC’s Owncloud Core Processing Library is now composed of a “client side” component and “server side” component (IICloud’s Addon).

The “client side” part of the library (“user side” vs. “network/server side” in the illustrations above and below) can be used from Processing, in order to get access to OwnCloud server(s) and manipulate files. The benefit of the core library resides in the fact that it mashups all together a set of heterogeneous functionalities in one single library (it has been therefore renamed I&IC OwnCloud Core Processing Library as it is more closely related to our research).

(The reasons why an I&IC’s) OwnCloud Core Processing Library

Beside the reflection produced by the overall Inhabiting & Interfacing the Cloud(s) project and the related necessity to provide “access to tools” to a larger community (largely described in the founding document of the project and in a former post about the setting up of this library), new paradigms may arise in the global organization of servers farms. These new paradigms may in return generate new ways to organize files on cloud servers (by a different control of the redundancy principle for example, or a different use of file’s duplication, etc.), allowing for new projects.

In order to answer the stakes of the I&IC design research and to prepare such output/proposals, we have developed the OwnCloud Core Processing Library that will allow to setup a software layer on top of the hardware layer.

 

To download and learn how to use the OwnCloud Core Processing Library, we’ve prepared a post in the Cook Books section of this site.

Cookbook > How to set up Processing to use the OwnCloud Core Processing Library

We will describe how to use the OwnCloud Core Processing Library within the Processing framework, starting from a blank sketch. Library’s functions will be refined and new ones may be developped, some additional libraries will be added as well in order to propose high level functions deeper linked to the IICloud(s) project.

Toward OwnCloud Core Processing Library

The purpose of the OwnCloud Core Processing Library is to give the possibility to program “cloud functionalities” within a well known and simplified designer oriented programming language (and community): Processing.

 

Therefore, the OwnCloud Core Processing Library linked with our personal cloud merges the Open Collaboration Service (OCS) Share API with higher level functions in order to implement seamlessly “search&share files” applications written in the well known designers oriented Processing programming language. This will soon become available to everyone on the I&IC website. The workshops we are currently running / will run during the coming weeks are helping/will help us fine tune its functionalities.

 

The OwnCloud Core Processing Library allows the automation of the action of sharing files and the action of file tagging within an open source OwnCloud environment. Search&Sharing tasks can be threaded and/or interdependent, everything depending on the kind of results expected from one application to another. Thus, these actions can be driven by unmanned processes, decision-making (copy, delete, share one or several files) based on related metadata (i.e. metadata relation/link) or based on external data, dug from the Internet or networked/connected items/things.
