The First on-Line conference on Metadata and Semantics Research (MTSR'05) is an on-line conference aimed at a different type of interaction than that provided by conventional conferences.

The papers submitted to the conference will undergo the standard blind peer-review procedure, and after that, accepted papers will be included in on-line proceedings. On-line proceedings will be available prior to the conference to maximize opportunities for discussion.

Authors of accepted papers will have the responsibility to present their papers and answer questions in virtual sessions, with asynchronous communication, during the days of the conference. The discussions will be recorded and used as a source for improving the papers presented, which will later be published in post-proceedings after the conference.
