#

# cli_getCopyrightInfo.sh -- This function outputs copyright

# information based on action value (ACTIONVAL) variable.

#

# The copyright information is printed to show the fact that one

# person how creates something has the creation rights over that

# something he/she created. An so, the legal power to release his/her

# creation under the ethical terms of whatever license he/she

# considers more appropriate, in order to distribute his/her creation.

#

# Inside CentOS Artwork Repository, we print copyright information in

# the following image-related components:

#

#   1. The artistic motifs, to define the visual style of themes.

#

#      The copyright information of artistic motifs is owned by the

#      person who creates the artistic motif (i.e., the artistic motif

#      author). The copyright information of artistic motifs is

#      specified in the `authors.txt' file placed inside the artistic

#      motif directory structure. The copyright information of

#      artistic motifs is printed in imagesunder

#      trunk/Identity/Themes/Motifs/$THEME/Concept directory structure

#      only.

# 

#   2. The design models, to define the characteristics of themes.

# 

#      The copyright information of design models is owned by the

#      person who creates the design model (i.e., the design model

#      author). The copyright information of design models is

#      specified in the metadata of each scalable vector graphic that

#      make a design model on its own. The copyright information of

#      design models is not printed in images.

#

#   3. The CentOS themes, to cover each visual manifestation of The

#      CentOS Project corporate visual identity.  A CentOS theme is

#      made of many different images connected among themselves by

#      mean of a uniform visual pattern (artistic motif + design

#      model).

#

#      The copyright information of CentOS themes is owned by The

#      CentOS Project. Instead of printing the copyright information

#      over all images inside one CentOS theme, the copyright

#      information of CentOS themes is printed only on images related

#      to Anaconda progress first slides.

#

#      The copyright information printed on Anaconda progress first

#      slides is used to print the creation rights of The CentOS

#      Project over its creation (i.e., The CentOS Distribution) not

#      The CentOS Theme itself.

# 

# At this point, we've defined who own the creation rights of image

# components. Now, it is important to remark that if we need to show

# one creation copyright, in different places, all references to the

# same cration copyright information should be the same. Cannot be any

# ambiguity among them. The best way to reach this is having just one

# unique definition, and build images using that unique copyright

# definition as reference.

#     

# Another relevant point, we need to be aware of, is that related to

# the licenses. As creators has the creation rights, they have the

# right to distribute their work as their consideration.  If creators

# release their creations under the terms of a privatizing license,

# that creation will be almost useless for The CentOS Community. So,

# in order for creations to be useful in The CentOS Community,

# creators should distribution their creations under the terms of a

# license that grants the freedom of using, studying, changing and

# releasing improved versions of them. Likewise, the license should

# prevent any privatizing practice or any kind of darkness that put in

# risk the freedom of The CentOS Community.

# 

# What license should be used to distribute images (and the components

# used to build them) is a decision for The CentOS Community to take.

# The license adopted, by The CentOS Community, specifies the ethical

# terms The CentOS Community is agree to work with. It is a reference

# we all have to agree with and follow in the sake of our community

# and ourselves freedom.  That's why license selection has to be a

# collective decision, and also be constantly in question.

#

# I'm not a lawyer. So, I can't give details of something I don't know

# certainly.  All I've done so far is using my intuition and basic

# understanding of what copyright and license is. So, if you have a

# deeper understanding and experience in such legal topics, please

# feel free to make your own revisions to ideas described here.

#         

# In the sake of covering copyright information and license needs

# inside centos-art.sh script, all images produced by `centos-art.sh'

# script will be released using the copyright information of his/her

# creator (see above) and the license Creative Common

# Attribution-ShareAlike 3.0 License

# (http://creativecommons.org/licenses/by-sa/3.0/).  

#

# The Creative Common Attribution-ShareAlike 3.0 License has been

# adopted in The CentOS Wiki (http://wiki.centos.org/) and seems to be

# good as well to distribute image-specific creations under CentOS

# Artwork Repository. Of course, as licenses are always questionable,

# the one we've choosed could be changed in the future after a

# collective discussion in the CentOS mailing list, in order to better

# reflect the ethical feelings of our community.
