Update to legal notice, made Feb 2012, modified Sep 2013. We would like to clarify that we are using a convention where multiple names in the Apache copyright headers, for example // Copyright 2009-2012 Yanmin Qian Arnab Ghoshal // 2013 Vassil Panayotov does not signify joint ownership of copyright of that file, except in cases where all those names were present in the original release made in March 2011-- you can use the version history to work this out, if this matters to you. Instead, we intend that those contributors who later modified the file, agree to release their changes under the Apache license. The conventional way of signifying this is to duplicate the Apache headers at the top of each file each time a change is made by a different author, but this would quickly become impractical. Where the copyright header says something like: // Copyright 2013 Johns Hopkins University (author: Daniel Povey) it is because the individual who wrote the code was at that institution as an employee, so the copyright is owned by the university (and we will have checked that the contributions were in accordance with the open-source policies of the institutions concerned, including getting them vetted individually where necessary). From a legal point of view the copyright ownership is that of the institution concerned, and the (author: xxx) in parentheses is just informational, to identify the actual person who wrote the code, and is not intended to have any legal implications. In some cases, however, particularly early on, we just wrote the name of the university or company concerned, without the actual author's name in parentheses. If you see something like // Copyright 2009-2012 Arnab Ghoshal Microsoft Corporation it does not imply that Arnab was working for Microsoft, it is because someone else contributed to the file while working at Microsoft (this would be Daniel Povey, in fact, who was working at Microsoft Research at the outset of the project). The list of authors of each file is in an essentially arbitrary order, but is often chronological if they contributed in different years. The original legal notice is below. Note: we are continuing to modify it by adding the names of new contributors, but at any given time, the list may be out of date. --- Legal Notices Each of the files comprising Kaldi v1.0 have been separately licensed by their respective author(s) under the terms of the Apache License v 2.0 (set forth below). The source code headers for each file specifies the individual authors and source material for that file as well the corresponding copyright notice. For reference purposes only: A cumulative list of all individual contributors and original source material as well as the full text of the Apache License v 2.0 are set forth below. Individual Contributors (in alphabetical order) Mohit Agarwal Tanel Alumae Gilles Boulianne Lukas Burget Dogan Can Guoguo Chen Gaofeng Cheng Cisco Corporation Pavel Denisov Ilya Edrenkin Ewald Enzinger Joachim Fainberg Daniel Galvez Pegah Ghahremani Arnab Ghoshal Ondrej Glembek Go Vivace Inc.
