Learning Layers
This project has received funding from the European
Union’s Seventh Framework Programme for research,
technological development and demonstration under grant
agreement no 318209 and from European Commision
under the grant 531262-LLP-2012-ES-KA3MP.
Scalable and easy to use framework
Novel, reliable approach for conflict resolution
Supports custom data types, e.g. JSON, XML
Good convergence time and low complexity
Key Contributions

Collaboration Engine handles the conflicts and
plugs in the various data types
Resolves occuring conflicts
Data types can be added programatically
Connectors work at protocol level
Connect peers between each other
Propagate operations to peers
WebRTC and XMPP are currently available
P2P Architecture
Enable near real-time collaboration
Solve P2P collaborative editing conflicts
Collaboration in Web browser: drawing, editing,
modeling, synchronizing, etc.
Shared Editing
YATA – shared editing in P2P architectures
Similar to Operational Transformation
Support for arbitrary data types (e.g. list-like,
tree-like, map-like, graph-like data)
Garbage collector mechanism for operations
Novel Approach: YATA
Enable near real-time collaboration in widget-
based applications
Implement support for further data types
Preserve and synchronize state across devices
