Re: JPL Planetary Ephemeris DE405
An expression of which observations may
be subject ot copyright, but the observations themselves,
(i.e., data) are not.
It seems an expression of data or source code
may be subject to protection, but the information
and algorithm are not sunject to copyright.
The latter may have implications the patent area.
102. Subject matter of copyright: In general
(a) Copyright protection subsists, in accordance with this title, in
original works of authorship fixed in any tangible medium of expression, now

otherwise communicated, either directly or with the aid of a machine or
device. Works of authorship include the following categories:
(1) literary works;
(2) musical works, including any accompanying words;
(3) dramatic works, including any accompanying music;
(4) pantomimes and choreographic works;
(5) pictorial, graphic, and sculptural works;
(6) motion pictures and other audiovisual works;
(7) sound recordings; and
(8) architectural works.
(b) In no case does copyright protection for an original work of authorship
extend to any idea, procedure, process, system, method of operation,
concept, principle, or discovery, regardless of the form in which it is
described, explained, illustrated, or embodied in such work.
103. Subject matter of copyright:
Compilations and derivative works
(a) The subject matter of copyright as specified by section 102 includes
compilations and derivative works, but protection for a work employing
preexisting material in which copyright subsists does not extend to any part
of the work in which such material has been used unlawfully.
(b) The copyright in a compilation or derivative work extends only to the
material contributed by the author of such work, as distinguished from the
preexisting material employed in the work, and does not imply any exclusive
right in the preexisting material. The copyright in such work is independent
of, and does not affect or enlarge the scope, duration, ownership, or
subsistence of, any copyright protection in the preexisting material.

As far as copyright law is concerned, there is no difference between
data and software.
For some programming languages, there is no difference between data and
Data is fundamentally different from software: for example, there is no
"source code" for DE405.
The source code for the ephemeris is physical observations of the stars,
planets, and other bodies in it.
