- 1. Open (P2P) Design. Workshop How to design collaboratively an open process? Massimo Menichinelli --------------------------------------------------------------------------- September 17th / 24th 2011 Pixelversity – Pixelache, Helsinki http://www.pixelache.ac/helsinki/pixelversity/programme-2011/open-p2p- design/ Presentation available at: http://www.slideshare.net/openp2pdesign
- 3. Internet and the Web enabled mass-collaboration A version (or revision) control system is a system that tracks incremental versions (or revisions) of fles and directories over time. It allows you to explore the changes which resulted in each of those versions and facilitates the arbitrary recall of the same. As the fles in the repository are changed, the repository remembers each version of those fles. * Backup and Restore * Synchronization * Short-term undo + Long-term undo * Track Changes * Track Ownership * Sandboxing * Branching and merging Source: http://svnbook.red-bean.com/en/1.6/svn.basic.version-control-basics.html

- 7. Subversion: an open source Version Control System Subversion manages fles and directories, and the changes made to them, over time. This allows you to recover older versions of your data or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of “time machine”.

- 8. Version Control System: the vocabulary (01) * Change A change (or dif) represents a specifc modifcation to a document under version control. * Checkout A check-out (or co) is the act of creating a local working copy from the repository. A user may specify a specifc revision or obtain the latest. Also refers to the same fles. * Commit A commit (checkin, ci) is the action of writing or merging the changes made in the working copy back to the repository. Also refers to the same fles. * Head The most recent commit. Source: http://en.wikipedia.org/wiki/Revision_control
- 9. Version Control System: the vocabulary (02) * Conflict A confict occurs when diferent parties make changes to the same document. A user must resolve the confict by combining the changes, or by selecting one change. * Merge A merge or integration is an operation in which two sets of changes are applied to a fle or set of fles. * Update An update (or sync) merges changes made in the repository (by other people, for example) into the local working copy. * Working copy The working copy is the local copy of fles from a repository, at a specifc time or revision. Conceptually, it is a sandbox. Source: http://en.wikipedia.org/wiki/Revision_control

- 12. Versioning model: the copy-modify-merge solution (01) In this model, each user's client contacts the project repository and creates a personal working copy. The private copies are merged together into a new version. Source: http://svnbook.red-bean.com/en/1.6/svn.basic.version-control-basics.html
