A copyright question
Here is a copyright question...
I came across some code for generating a guid unique over IEEE 802
address space and a time of 35 years.
The URL is http://www.theserverside.com/patterns/thread.jsp?thread_id=4976
The author is listed as Adrian Maclean, but I could find no way of
contacting them.
The code implements a standard IEEE algorithm.
What is the viability of using including this code in a greater whole
and donating the whole to the ASF?
I'm guessing it's a no-go, but could use some info from more
license-aware people.

Ok, still interested in answer, but probably will use java.rmi.dgc.VMID
for guid generation, especially since I would assume the referenced
code's use is no go because
1) ServerSide has copright to all site content
2) The authors name is on the code and no license is expressly stated,
so it probably defaults to the author retains all rights
I wish forums would have a policy stating "By posting code to this forum
you agree that the code shall be licensed under the Apache License", or
something similar.

Tim,
I like the idea of working on this, especially as a set of Cornerstone
services used by a UUIDService to generate UUIDs. At this time however
I am just using vmid to fill my immediate need. I have two apps that
need to be finished before I do the UUID services. If you don't mind
waiting I'll work with you on this.

Hello Bill,
I started on something quite a few months ago:
commons-lang welcomed adapting a UUID implementation.
The problem I ran into was - the consensus at the time was to use the Tyrex
UUID for various reasons (also found in Castor with slight changes.) And
elsewhere in exolab projects.
I started the discussion wanting to get the Axis uuid moved into commons.
http://marc.theaimsgroup.com/?l=jakarta-commons-dev&w=2&r=1&s=UUID&q=b
But since I want this as a pure Apache license class for the sake of reuse
in apache projects I did not know how to take from one license source Exolab
and put under ASL. I tried contacting Assaf Arkin; rather info@exolab.org
to see about a contribution put no luck.
--
Would you leave the original license in the file?
But then all ASF source must have the ASF license.
Would you pre-pend both licenses?
Add the Tyrex license to the distribution?
Reduce a modified Tyrex jar to distribute with only the 3 classes
and the license and uuid.properties? And call it something else?
--
FYI just noticed Turbine has org.apache.turbine.util.db.UUIdGenerator
that allows for a properties file with the MAC address.
(That was one of the requests from commons-lang.)
--
When I didn't get answers to these questions I toyed with creating
an implementation modeled after the Tyrex version. I planned to allow the
clock thread to die after some timeout between calls. No idea if that's
a smart thing or not; I also didn't understand the need to re-synchronize
with the System time? Can threads sleep longer than you say tell them - I
mean
I know load and thread priority come into play, but I thought not that long.
Anyhow, not feeling confident in what I was doing I decided to abandon it.
I know attachments sometimes don't make it, but I'll try to attach a rough
**draft** here. If you have interest in continuing this feel free or we can
work on
it together. I don't have a much time but I can make some somewhere and I'll
learn some stuff.
It would be nice to follow through on the original thought and get something
to
commons-lang identifiers; so all these UUID that are about might live in
commons.
Let me know your thoughts.
