   * provide a formal way to describe pointers to other //external bugs// in remote bugtrackers, set by and displayed for the persons interested in the bugs (more formal than URLs added in notes, since a //semantics// is defined for types of relations).
   * allow the use of such relations by //agents// which could automatically //monitor// such external bugs. A first use could be to notify these interested persons whenever a //status change// of the remote bug is noticed by agents, as is done by //bts-link// for the debbugs Debian bugtracker (or similar features).
 ===== Bug relationships =====
-Mantis already provides certain relationship_types in the "metadata", for property of relations between bugs. Currently however, this feature is only for linking local bugs (in the same mantis instance). Through the plugin, we propose to add additional relationship_types and also allow the current relationship_types for external bugs (also called remote bugs / external bugs ?).

Through the plugin, we propose to add additional relationship_types and also allow the current relationship_types for external bugs (also called remote bugs / external bugs ?). The new relationship_types could represent different semantics, like:
   * "See also" : meant for general URL pointing to other bugs without further semantics
   * "Forwarded upstream" : meant for distributions monitoring upstream projects for instance (and used by agents like bts-link)
+  * "External Duplicate of" : meant for duplicate bugs in other projects
 In addition, the current relationship types used for local bugs could also be used for external bugs (parent / child, etc.) It will be the administrator's duty to define the relationship types in an understandable way, and compatible with the agents capabilities (see below).
+==== Description of the data ====
 Each local bug is permitted to have multiple relationships which connect it to different external bugs. Each of these relations would have:

 The bts-link allowed to monitor a relation_type on a mantis instance will extract the previous state from the most recent entry notifying the status in its log. In case concurrent tools are running, the others will not use that log nor notify users through mantis, but they could run nevertheless, using usertags and separate notification mechanisms (described in another document).
+//Note : the following proposal is made in the frame of the [[https://picoforge.int-evry.fr/cgi-bin/twiki/view/Helios_wp3/Web/|Helios]] project working on the subject of bugtracker synchronisation.//
+Note that in waiting for this feature to be integrated in Mantis, we have devised a working version of bts-link anyway, see : http://permalink.gmane.org/gmane.comp.bug-tracking.mantis.devel/2457
