GSoC: Features of the Retroshare social network plugin

Content is obviously the most important element of a social network. Currently only support for plain text is implemented. The content can have an author, but this is not required.

Future: It would be nice to have support for images. This is very easy on the backend side, but it needs a frontend which scales the image to fit on the screen. With Retroshares file transfer capabilities it would also be possible to publish large files like audio and video files. It would be nice to restrict access to content to a set of people. Retroshare is prepared for this and it only needs small changes in the social network backend. Of course this requires a user interface to sort people into circles and to select circles.

Content alone is useless without a place where it gets displayed. As explained in a previous blog post, every piece of content is stored for its own. To make content visible it has to get referenced on a wall. This happens automatically on the own wall when creating a new post. It also gets triggered by clicking the share button. A reference always has an author.

Future: maybe allow to reference content from other services. For example if Retroshare gets a Photo Share service, allow to reference a picture or photo album on the wall.

A Wall is a place where a profile text, an avatar image and references to content are stored. A user subscribes to another user to download all posts referenced on the wall. The wall owner and others can reference content on a wall.

All new posts are collected and displayed in the news feed. A news feed shows the new content, the comments and how others interact with the content. Who commented this post? Who shared this post? Currently the news feed displays posts in the order in which they where received.

Future: it is probably desired to have a more advanced logic to sort news feed entries. Imagine a user comes online after a week and gets bombed by hundred new posts. It would be possible to sort news in two dimensions: topics and rating. Example: have one tab for content from close friends, and one tab for other content. Then calculate a score to display more important content at the top. This requires a bit of backend work, but it is doable.

Users can interact with content in two different ways: they can comment it, and they can share it. Sharing creates a reference to the content on the own wall, and thus forwards the content to friends. Comments are stored with the content, so everyone who received the content will also receive the comments.

Future: one can think of other ways to interact with content. Examples are like, bookmark, vote and hide. In general these interactions are each a form of tagging. For the backend it does not make a difference if content is tagged with “GSoC14” or “like” or 3.1415. This is more a matter on the frontend side: which meaning does the tag have for the user? How does the frontend show different tags? (star, heart, thumbs up, plus sign, text, …) How can the user filter posts with specific tags?

There has to be an entry point to let the user see the people around him. If the user recognizes a known person he might want to subscribe to this person. For now there is a widget to display all identities with their name and avatar image. Of course later this list should get filtered to fit on the screen. Retroshare circles could be used to make friends lists accessible to friends. This would allow automatic circle intersection to search for people the user probably knows.
